# ASiCSigner Component

The ASiCSigner class creates associated signature containers.

## Syntax

```text
secureblackbox.ASiCSigner
```

## Remarks

ASiCSigner provides functionality for creating and updating Associated Signature Containers (ASiC). ASiC containers are used to bind together data, signed objects, and electronic signatures or timestamps, and store them in a standardized, cross-platform ZIP-compatible file.

ASiC has gained wide use across European countries (as part of eIDAS regulation) and beyond. Alongside other AdES formats (CAdES, XAdES, PAdES), it provides convenience of storing sets of heterogeneous data objects within a compatible container, providing data retention, self-sufficiency, and high interoperability options.

ASiC uses CAdES, XAdES, and RFC3161 timestamps as its building blocks, effectively allowing to expand these formats beyond their single-object limitation.

ASiCSigner supports all the ASiC capabilities as defined in the respective [ETSI standards](https://ec.europa.eu/digital-building-blocks/sites/display/DIGITAL/Standards+and+specifications) (ETSI EN 319 162), in particular:

- ASiC-S (simple) and ASiC-E (extended) signature profiles.
- CAdES- and XAdES-based signatures.
- RFC 3161 timestamps.
- All ETSI signature profiles (including B-B, B-T, B-LT, B-LTA).
- Short-term, long-term, and archivable signatures.
- Complete chain of trust validation process, using local, global, nation-specific (EUTL), or custom trust.
- Signing with local, remote, and hardware-based private keys.
- Creating new containers or updating/extending existing ones.
- Online and offline modes.

The component is being actively maintained and updated to account for ongoing developments in AdES world. For more than 10 years, our engineers have been active participants of ETSI Plugtests events, to make sure that our e-Signature infrastructure is compliant and highly interoperable.

ASiCSigner supports several work modes that differ in complexity, allowing for both 'quick' and 'flexible' use. The simple mode assumes providing the [SourceFiles](#sourcefiles-property-asicsigner-component), the [OutputFile](#outputfile-property-asicsigner-component), the SigningCertificate, and calling the one-pass [Sign](#sign-method-asicsigner-component) method. In this case the component will use its intelligence to create the most appropriate signature with the given parameters over the provided files.

More complex tune-up may involve fine-grained adjustment of properties of the NewSignature object, providing custom validation material (certificates, OCSPs, CRLs), setting up customized timestamping handlers for non-standard TSAs, or using a pre-defined signature [Profile](#profile-property-asicsigner-component). You can also choose to work with the container step-by-step, by splitting the one-pass operation into individual [Open](#open-method-asicsigner-component)/[CreateNew](#createnew-method-asicsigner-component), [Sign](#sign-method-asicsigner-component), and [Close](#close-method-asicsigner-component) calls.

```text
ASiCSigner signer = new ASiCSigner();

signer.setSourceFiles("./MyFile.txt \n./MySecondFile.txt"); // set path of the file/files you want to sign
signer.setOutputFile("./SignedFile.scs"); // set path where the output should be saved

signer.setSigningCertificate(new Certificate("./test.pfx","test")); // set the signing certificate
signer.setExtended(true); // since we are signing multiple documents we set extended to true

// set the signature type
signer.getNewSignature().setSignatureType(ASiCSignature.castCAdES);

signer.sign();
```

Returns the raw certificate data in DER format.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) CertBytes(CertIndex int32) ([]byte, error)
```

## Remarks

Returns the raw certificate data in DER format.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-asicsigner-component) property.

This property is read-only.

## Data Type

**[]byte**

# CertCA Property ([ASiCSigner](#asicsigner-component) Component)

Indicates whether the certificate has a CA capability.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) CertCA(CertIndex int32) (bool, error)
```

## Default Value

false

## Remarks

Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled.

Set this property when generating a new certificate to have its Basic Constraints extension generated automatically.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-asicsigner-component) property.

This property is read-only.

## Data Type

**bool**

# CertCAKeyID Property ([ASiCSigner](#asicsigner-component) Component)

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) CertCAKeyID(CertIndex int32) ([]byte, error)
```

## Remarks

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. [CertificateManager](#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [CertSubjectKeyID](#certsubjectkeyid-property-asicsigner-component) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-asicsigner-component) property.

This property is read-only.

## Data Type

**[]byte**

# CertType Property ([ASiCSigner](#asicsigner-component) Component)

Returns the type of the entity contained in the Certificate object.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) CertType(CertIndex int32) (int32, error)
```

## Possible Values

```text
0   // Unknown1   // X509Certificate2   // X509CertificateRequest
```

## Default Value

0

## Remarks

Returns the type of the entity contained in the [Certificate](#Type_Certificate) object.

A [Certificate](#Type_Certificate) object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate.

Use the [CertificateManager](#CertificateManager) struct to load or create new certificate and certificate requests objects.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-asicsigner-component) property.

This property is read-only.

## Data Type

**int32**

# CertCRLDistributionPoints Property ([ASiCSigner](#asicsigner-component) Component)

Contains a list of locations of CRL distribution points used to check this certificate's validity.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) CertCRLDistributionPoints(CertIndex int32) (string, error)
```

## Default Value

""

## Remarks

Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-asicsigner-component) property.

This property is read-only.

## Data Type

**string**

# CertCurve Property ([ASiCSigner](#asicsigner-component) Component)

Specifies the elliptic curve associated with the certificate's public key.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) CertCurve(CertIndex int32) (string, error)
```

## Default Value

""

## Remarks

Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

func (obj *ASiCSigner) CertKeyBits(CertIndex int32) (int32, error)
```

## Default Value

0

## Remarks

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the [CertPublicKeyBytes](#certpublickeybytes-property-asicsigner-component) or [CertPrivateKeyBytes](#certprivatekeybytes-property-asicsigner-component) property would typically contain auxiliary values, and therefore be longer.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-asicsigner-component) property.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) CertSubjectKeyID(CertIndex int32) ([]byte, error)
```

## Remarks

Contains a unique identifier of the certificate's cryptographic key.

Subject Key Identifier is a certificate extension which allows a specific public key to be associated with a certificate holder. Typically, subject key identifiers of CA certificates are recorded as respective CA key identifiers in the subordinate certificates that they issue, which facilitates chain building.

The [CertSubjectKeyID](#certsubjectkeyid-property-asicsigner-component) and [CertCAKeyID](#certcakeyid-property-asicsigner-component) properties of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.

The *CertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [CertCount](#certcount-property-asicsigner-component) property.

This property is read-only.

# ExternalCryptoKeyID Property ([ASiCSigner](#asicsigner-component) Component)

The ID of the pre-shared key used for DC request authentication.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) ExternalCryptoKeyID() (string, error)func (obj *ASiCSigner) SetExternalCryptoKeyID(value string) error
```

## Default Value

""

## Remarks

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use [ExternalCryptoKeySecret](#externalcryptokeysecret-property-asicsigner-component) to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example:

```text
  signer.ExternalCrypto.KeyID = "MainSigningKey";
  signer.ExternalCrypto.KeySecret = "abcdef0123456789";
```

## Data Type

**string**

# ExternalCryptoKeySecret Property ([ASiCSigner](#asicsigner-component) Component)

```

## Default Value

1

## Remarks

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

Certificate Revocation Lists (CRLs) and Online Certificate Status Protocol (OCSP) responses serve the same purpose of ensuring that the certificate had not been revoked by the Certificate Authority (CA) at the time of use. Depending on your circumstances and security policy requirements, you may want to use either one or both of the revocation information source types.

|  |  |  |
| --- | --- | --- |
| crcNone | 0 | No revocation checking. |
| crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL | 2 | All provided CRL endpoints will be checked, and all checks must succeed. |
| crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. |
| crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. |
| crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. |
| crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. |
| crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. |

This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

NOTE: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

NOTE: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

## Default Value

""

## Remarks

Use this property to provide the address of the Time Stamping Authority (TSA) server to be used for timestamping the signature.

SecureBlackbox supports RFC3161-compliant timestamping servers, available via HTTP or HTTPS.

If your timestamping service enforces credential-based user authentication (basic or digest), you can provide the credentials in the same URL:

http://user:password@timestamp.server.com/TsaService

For TSAs using certificate-based TLS authentication, provide the client certificate via the TLSClientChain property.

If this property is left empty, no timestamp will be added to the signature.

Starting from summer 2021 update (Vol. 2), the *virtual* timestamping service is supported, which allows you to intervene in the timestamping routine and provide your own handling for the TSA exchange. This may be handy if the service that you are requesting timestamps from uses a non-standard TSP protocol or requires special authentication option.

To employ the virtual service, assign an URI of the following format to this property:

virtual://localhost?hashonly=true&includecerts=true&reqpolicy=1.2.3.4.5&halg=SHA256&ignorenonce=true

Subscribe to [Notification](#notification-event-asicsigner-component) event to get notified about the virtualized timestamping event. The EventID of the timestamping event is TimestampRequest. Inside the event handler, read the base16-encoded request from the EventParam parameter and forward it to the timestamping authority. Upon receiving the response, pass it back to the component, encoded in base16, via the TimestampResponse config property:

component.Config("TimestampResponse=308208ab...");

Note that all the exchange with your custom TSA should take place within the same invocation of the Notification event.

The *hashonly* parameter of the virtual URI tells the component to only return the timestamp message imprint via the EventParam parameter. If set to false, EventParam will contain the complete RFC3161 timestamping request.

The *includecerts* parameter specifies that the requestCertificates parameter of the timestamping request should be set to true.

The *reqpolicy* parameter lets you specify the request policy, and the *halg* parameter specifies the hash algorithm to use for timestamping.

The *ignorenonce* parameter allows you to switch off client nonce verification to enable compatibility with TSA services that do not support nonce mirroring.

All the parameters are optional.

# TLSRevocationCheck Property ([ASiCSigner](#asicsigner-component) Component)

Specifies the kind(s) of revocation check to perform.

## Syntax

*Go Syntax*

```

## Default Value

1

## Remarks

Specifies the kind(s) of revocation check to perform.

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

|  |  |  |
| --- | --- | --- |
| crcNone | 0 | No revocation checking. |
| crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL | 2 | All provided CRL endpoints will be checked, and all checks must succeed. |
| crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. |
| crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. |
| crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. |
| crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. |
| crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. |

This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

NOTE: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

NOTE: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

# TrustedCertCount Property ([ASiCSigner](#asicsigner-component) Component)

The number of records in the TrustedCert arrays.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) TrustedCertCount() (int32, error)func (obj *ASiCSigner) SetTrustedCertCount(value int32) error
```

## Default Value

0

## Remarks

This property controls the size of the following arrays:

- [TrustedCertBytes](#trustedcertbytes-property-asicsigner-component)
- [TrustedCertHandle](#trustedcerthandle-property-asicsigner-component)

The array indices start at *0* and end at *TrustedCertCount - 1*.

## Data Type

**int32**

# TrustedCertBytes Property ([ASiCSigner](#asicsigner-component) Component)

Returns the raw certificate data in DER format.

## Syntax

*Go Syntax*

```text

The *TrustedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [TrustedCertCount](#trustedcertcount-property-asicsigner-component) property.

This property is read-only.

## Data Type

**[]byte**

# TrustedCertHandle Property ([ASiCSigner](#asicsigner-component) Component)

Allows to get or set a 'handle', a unique identifier of the underlying property object.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) TrustedCertHandle(TrustedCertIndex int32) (int64, error)func (obj *ASiCSigner) SetTrustedCertHandle(TrustedCertIndex int32, value int64) error
```

## Default Value

0

## Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation.

```text
  pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
```

The *TrustedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [TrustedCertCount](#trustedcertcount-property-asicsigner-component) property.

## Data Type

**int64**

# ValidationMoment Property ([ASiCSigner](#asicsigner-component) Component)

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) ValidationMoment() (string, error)func (obj *ASiCSigner) SetValidationMoment(value string) error
```

## Default Value

""

## Remarks

Use this property to specify the moment in time at which signature validity should be established. The time is in UTC. Leave the setting empty to stick to the default moment (either the signature creation time or the current time).

The validity of the same signature may differ depending on the time point chosen due to temporal changes in chain validities, revocation statuses, and timestamp times.

## Data Type

**string**

# AddFile Method ([ASiCSigner](#asicsigner-component) Component)

Use this method to add a file to the archive.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) AddFile() error
```

## Remarks

This method allows you to add multiple files to the archive.

There are several ways in which you can provide files to ASiCSigner:

- Assign a file list to [SourceFiles](#sourcefiles-property-asicsigner-component) property.
- Assign the file name to [SourceName](#sourcename-property-asicsigner-component), and the file body to [SourceBytes](#sourcebytes-property-asicsigner-component) or SourceStream.

 All files assigned to the above properties will be added to the archive automatically: you don't need to call AddFile to add them.

If, however, you need to add more than one in-memory file, or add more than one bunch of files using [SourceFiles](#sourcefiles-property-asicsigner-component), AddFile may be of good use. Effectively, it saves the file data provided through the above properties in ASiCSigner, releasing these properties for the next file(s). For example:

```text
  signer.SourceName = "file1.txt";
  signer.SourceBytes = Encoding.UTF8.GetBytes("Human progress is not measured by industry.");
  signer.AddFile(); // this saves the above data in the component, allowing you to add the next file

  signer.SourceName = "file2.txt";
  signer.SourceBytes = Encoding.UTF8.GetBytes("It is measured by the value you place on a life.");
  signer.AddFile(); // this adds the second file

  signer.SourceName = "file3.txt";
  signer.SourceBytes = Encoding.UTF8.GetBytes("An unimportant life. A life without privilege.");
  // You don't need to AddFile() the final file: this will be picked by ASiCSigner from the properties automatically
```

# Close Method ([ASiCSigner](#asicsigner-component) Component)

Closes an opened container.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) Close(SaveChanges bool) error
```

## Remarks

Use this method to close a previously opened container. Set *SaveChanges* to true to apply any changes made.

# Config Method ([ASiCSigner](#asicsigner-component) Component)

Sets or retrieves a configuration setting.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) Config(ConfigurationString string) (string, error)
```

## Remarks

Config is a generic method available in every struct. It is used to set and retrieve [configuration settings](#config-settings-asicsigner-component) for the struct.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, access to these *internal properties* is provided through the Config method.

To set a configuration setting named *PROPERTY*, you must call *Config("PROPERTY=VALUE")*, where *VALUE* is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a [configuration setting](#config-settings-asicsigner-component), you must call *Config("PROPERTY")*. The value will be returned as a string.

# CreateNew Method ([ASiCSigner](#asicsigner-component) Component)

Creates a new ASiC container.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) CreateNew() error
```

## Remarks

Use this method to create a new container file.

The container will be kept in memory until written down with [Close](#close-method-asicsigner-component) method.

# DoAction Method ([ASiCSigner](#asicsigner-component) Component)

Performs an additional action.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) DoAction(ActionID string, ActionParams string) (string, error)
```

## Remarks

DoAction is a generic method available in every struct. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insensitive) of the action is provided in the *ActionID* parameter.

*ActionParams* contains the value of a single parameter, or a list of multiple parameters for the action in the form of *PARAM1=VALUE1;PARAM2=VALUE2;...*.

Common ActionIDs:

|  |  |  |  |
| --- | --- | --- | --- |
| Action | Parameters | Returned value | Description |
| ResetTrustedListCache | none | none | Clears the cached list of trusted lists. |
| ResetCertificateCache | none | none | Clears the cached certificates. |
| ResetCRLCache | none | none | Clears the cached CRLs. |
| ResetOCSPResponseCache | none | none | Clears the cached OCSP responses. |

# ExtractAsyncData Method ([ASiCSigner](#asicsigner-component) Component)

```text
func (obj *ASiCSigner) ExtractFiles(SigLabel string) error
```

## Remarks

Use this method to extract all files covered by the signature *SigLabel* to [OutputPath](#outputpath-property-asicsigner-component). Set *SigLabel* to "" to extract all the files included in the container.

# Open Method ([ASiCSigner](#asicsigner-component) Component)

Opens an existing container for signing or updating.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) Open() error
```

## Remarks

Use this method to open a container for signing or updating. When finished, call [Close](#close-method-asicsigner-component) to complete or discard the operation.

# Reset Method ([ASiCSigner](#asicsigner-component) Component)

Resets the class settings.

## Syntax

*Go Syntax*

```text

# SelectInfo Method ([ASiCSigner](#asicsigner-component) Component)

Select signature information for a specific entity.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) SelectInfo(EntityLabel string, InfoType int32, ClearSelection bool) error
```

## Remarks

Use this method to select (or filter) signature-related information for a specific signature element.

Provide the unique label of the entity that you are interested in via the *EntityLabel* parameter. Use one of the following filters, or their combination, to specify what information you are interested in:

|  |  |  |
| --- | --- | --- |
| sitEntity | 1 | Select the current entity |
| sitParentEntity | 2 | Select the parent entity of the current entity |
| sitTimestamps | 4 | Select all timestamps covering the current entity |
| sitSignatures | 8 | Select all signatures covering the current entity |
| sitSigningChain | 16 | Select the signing chain of the current entity |
| sitEmbeddedCertificates | 256 | Select all certificates embedded in the current entity |
| sitEmbeddedCRLs | 512 | Select all CRLs embedded in the current entity |
| sitEmbeddedOCSPs | 1024 | Select all OCSP responses embedded in the current entity |
| sitEmbeddedRevInfo | 1792 | Select the whole pack of embedded revocation information (certificates, CRLs and OCSPs) |
| sitUsedCertificates | 4096 | Select all the certificates used to validate this entity's chain |
| sitUsedCRLs | 8192 | Select all the CRLs used to validate this entity's chain |
| sitUsedOCSPs | 16384 | Select all the OCSP responses used to validate this entity's chain |

This method is useful if you would like to read/display detailed information about a particular signature or timestamp.

# Sign Method ([ASiCSigner](#asicsigner-component) Component)

Signs the chosen files and packs them into an ASiC archive.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) Sign() error
```

## Remarks

Use this method to create a new ASiC signature container in accordance with the component setup.

# SignAsyncBegin Method ([ASiCSigner](#asicsigner-component) Component)

Initiates the asynchronous signing operation.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) SignAsyncBegin() (string, error)
```

## Remarks

When using the DC framework, call this method to initiate the asynchronous signing process. Upon completion, a pre-signed copy of the document will be saved in [OutputFile](#outputfile-property-asicsigner-component) (or OutputStream). Keep the pre-signed copy somewhere local, and pass the returned string ('the request state') to the DC processor for handling.

Upon receiving the response state from the DC processor, assign the path to the pre-signed copy to [InputFile](#inputfile-property-asicsigner-component) (or InputStream), and call [SignAsyncEnd](#signasyncend-method-asicsigner-component) to finalize the signing.

Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the SigningCertificate property.

Use the *ExternalCrypto.AsyncDocumentID* property to supply a unique document ID to include in the request. This is helpful when creating batches of multiple async requests, as it allows you to pass the whole response batch to [SignAsyncEnd](#signasyncend-method-asicsigner-component) and expect it to recover the correct response from the batch automatically.

*AsyncState* is a message of the distributed cryptography (DC) protocol. The DC protocol is based on the exchange of async states between a DC client (an application that wants to sign a PDF, XML, or Office document) and a DC server (an application that controls access to the private key). An async state can carry one or more signing requests, comprised of document hashes, or one or more signatures produced over those hashes.

In a typical scenario you get a client-side async state from the SignAsyncBegin method. This state contains document hashes to be signed on the DC server side. You then send the async state to the DC server (often represented by the DCAuth struct), which processes it and produces a matching signature state. The async state produced by the server is then passed to the [SignAsyncEnd](#signasyncend-method-asicsigner-component) method.

# SignAsyncEnd Method ([ASiCSigner](#asicsigner-component) Component)

Completes the asynchronous signing operation.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) SignAsyncEnd(AsyncReply string) error
```

## Remarks

When using the DC framework, call this method upon receiving the response state from the DC processor to complete the asynchronous signing process.

Before calling this method, assign the path to the pre-signed copy of the document obtained from the prior [SignAsyncBegin](#signasyncbegin-method-asicsigner-component) call to [InputFile](#inputfile-property-asicsigner-component) (or InputStream). The method will embed the signature into the pre-signed document, and save the complete signed document to [OutputFile](#outputfile-property-asicsigner-component) (or OutputStream).

Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the SigningCertificate property.

Use the *ExternalCrypto.AsyncDocumentID* parameter to pass a specific document ID if using batched AsyncReply. If used, it should match the value provided on the pre-signing ([SignAsyncBegin](#signasyncbegin-method-asicsigner-component)) stage.

*AsyncState* is a message of the distributed cryptography (DC) protocol. The DC protocol is based on the exchange of async states between a DC client (an application that wants to sign a PDF, XML, or Office document) and a DC server (an application that controls access to the private key). An async state can carry one or more signing requests, comprised of document hashes, or one or more signatures produced over those hashes.

In a typical scenario you get a client-side async state from the [SignAsyncBegin](#signasyncbegin-method-asicsigner-component) method. This state contains document hashes to be signed on the DC server side. You then send the async state to the DC server (often represented by the DCAuth struct), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.

# SignExternal Method ([ASiCSigner](#asicsigner-component) Component)

Signs the document using an external signing facility.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) SignExternal() error
```

## Remarks

Use this method to create an ASiC signature using an external signing facility for the cryptographic computations. SignExternal delegates the low-level signing operation to an external, remote, or custom signing engine. This method is useful if the signature has to be made by a device accessible through a custom or non-standard signing interface.

When all preparations are done and hash is computed, the struct fires [ExternalSign](#externalsign-event-asicsigner-component) event which allows to pass the hash value for signing.

# Timestamp Method ([ASiCSigner](#asicsigner-component) Component)

Use this method to add timestamp.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) Timestamp(SigLabel string, TimestampType int32) error
```

## Remarks

Call this method to timestamp the signature. Use the [TimestampServer](#timestampserver-property-asicsigner-component) property to provide the address of the TSA (Time Stamping Authority) server which should be used for timestamping. Use the *TimestampType* parameter to specify the type of timestamp to create Available options:

# Upgrade Method ([ASiCSigner](#asicsigner-component) Component)

Upgrades existing CAdES or XAdES signature to a new level.

## Syntax

*Go Syntax*

```text
func (obj *ASiCSigner) Upgrade(SigLabel string, UpgradeKind int32) error
```

## Remarks

CAdES and XAdES standard defines a number of different 'levels' or 'forms' of signatures which can be used for different purposes. Use this method to upgrade CAdES or XAdES signature to a new form or level specified by *UpgradeKind*.

# ContainerLoaded Event ([ASiCSigner](#asicsigner-component) Component)

This event is fired when the container has been loaded into memory.

## Syntax

*Go Syntax*

```text
// ASiCSignerContainerLoadedEventArgs carries the ASiCSigner ContainerLoaded event's parameters.
type ASiCSignerContainerLoadedEventArgs struct {...}

func (args *ASiCSignerContainerLoadedEventArgs) Cancel() bool
func (args *ASiCSignerContainerLoadedEventArgs) SetCancel(value bool)

// ASiCSignerContainerLoadedEvent defines the signature of the ASiCSigner ContainerLoaded event's handler function.
type ASiCSignerContainerLoadedEvent func(sender *ASiCSigner, args *ASiCSignerContainerLoadedEventArgs)

func (obj *ASiCSigner) GetOnContainerLoadedHandler() ASiCSignerContainerLoadedEvent
func (obj *ASiCSigner) SetOnContainerLoadedHandler(handlerFunc ASiCSignerContainerLoadedEvent)
```

## Remarks

The handler for this event is a good place to check for any existing signatures and validate them if required.

Set *Cancel* to true to terminate document processing on this stage.

# Error Event ([ASiCSigner](#asicsigner-component) Component)

Information about any errors that occur during signing or archiving.

## Syntax

*Go Syntax*

```text
// ASiCSignerErrorEventArgs carries the ASiCSigner Error event's parameters.
type ASiCSignerErrorEventArgs struct {...}

func (args *ASiCSignerErrorEventArgs) ErrorCode() int32
func (args *ASiCSignerErrorEventArgs) Description() string
// ASiCSignerErrorEvent defines the signature of the ASiCSigner Error event's handler function.
type ASiCSignerErrorEvent func(sender *ASiCSigner, args *ASiCSignerErrorEventArgs)

func (obj *ASiCSigner) GetOnErrorHandler() ASiCSignerErrorEvent
func (obj *ASiCSigner) SetOnErrorHandler(handlerFunc ASiCSignerErrorEvent)
```

## Remarks

The event is fired in case of exceptional conditions which occur during signing or archiving of data.

*ErrorCode* contains an error code and *Description* contains a textual description of the error.

# ExternalSign Event ([ASiCSigner](#asicsigner-component) Component)

Handles remote or external signing initiated by the SignExternal method or other source.

## Syntax

*Go Syntax*

```text
// ASiCSignerExternalSignEventArgs carries the ASiCSigner ExternalSign event's parameters.
type ASiCSignerExternalSignEventArgs struct {...}

func (args *ASiCSignerExternalSignEventArgs) OperationId() string
func (args *ASiCSignerExternalSignEventArgs) HashAlgorithm() string
func (args *ASiCSignerExternalSignEventArgs) Pars() string
func (args *ASiCSignerExternalSignEventArgs) Data() string
func (args *ASiCSignerExternalSignEventArgs) SignedData() string
func (args *ASiCSignerExternalSignEventArgs) SetSignedData(value string)

// ASiCSignerExternalSignEvent defines the signature of the ASiCSigner ExternalSign event's handler function.
type ASiCSignerExternalSignEvent func(sender *ASiCSigner, args *ASiCSignerExternalSignEventArgs)

func (obj *ASiCSigner) GetOnExternalSignHandler() ASiCSignerExternalSignEvent
func (obj *ASiCSigner) SetOnExternalSignHandler(handlerFunc ASiCSignerExternalSignEvent)
```

## Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of *Data* to the signer, obtain the signature, and pass it back to the struct via the *SignedData* parameter.

*OperationId* provides a comment about the operation and its origin. It depends on the exact struct being used, and may be empty. *HashAlgorithm* specifies the hash algorithm being used for the operation, and *Pars* contains algorithm-dependent parameters.

The struct uses base16 (hex) encoding for the *Data*, *SignedData*, and *Pars* parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following:

```text
signer.OnExternalSign += (s, e) =>
{
       var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable);
       var key = (RSACryptoServiceProvider)cert.PrivateKey;

       var dataToSign = e.Data.FromBase16String();
       var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1");
       e.SignedData = signedData.ToBase16String();
};
```

# FileExtractionStart Event ([ASiCSigner](#asicsigner-component) Component)

Signifies the start of a file extraction process.

## Syntax

*Go Syntax*

```text
// ASiCSignerFileExtractionStartEventArgs carries the ASiCSigner FileExtractionStart event's parameters.
type ASiCSignerFileExtractionStartEventArgs struct {...}

func (args *ASiCSignerFileExtractionStartEventArgs) FileName() string
func (args *ASiCSignerFileExtractionStartEventArgs) FileSize() int64
func (args *ASiCSignerFileExtractionStartEventArgs) ModDate() string
func (args *ASiCSignerFileExtractionStartEventArgs) Extract() bool
func (args *ASiCSignerFileExtractionStartEventArgs) SetExtract(value bool)

func (args *ASiCSignerFileExtractionStartEventArgs) DestFile() string
func (args *ASiCSignerFileExtractionStartEventArgs) SetDestFile(value string)

// ASiCSignerFileExtractionStartEvent defines the signature of the ASiCSigner FileExtractionStart event's handler function.
type ASiCSignerFileExtractionStartEvent func(sender *ASiCSigner, args *ASiCSignerFileExtractionStartEventArgs)

func (obj *ASiCSigner) GetOnFileExtractionStartHandler() ASiCSignerFileExtractionStartEvent
func (obj *ASiCSigner) SetOnFileExtractionStartHandler(handlerFunc ASiCSignerFileExtractionStartEvent)
```

## Remarks

This event fires for every file located in the archive and matching the ExtractionMode setting before it is to be extracted.

*DestFile* indicates the path where the file will be saved to. You can alter the destination path here, by providing an alternative extraction path.

Set *DestFile* to an empty string and provide a stream object via the OutputStream property if you prefer to save the data to a stream instead of file.

If *DestFile* is set to an empty string and OutputStream is unassigned, the file will not be extracted.

Alternatively, you can request the extracted content to be saved into a byte array. To do this, leave *DestFile* and OutputStream empty, and keep the *Extract* parameter enabled.

Please take care when extracting large files into byte arrays, as those may consume large amounts of memory.

Note: if *DestFile* already exists, the struct will overwrite it. To prevent overwriting of existing files, subscribe to this event, and change *DestFile* when needed.

# Notification Event ([ASiCSigner](#asicsigner-component) Component)

This event notifies the application about an underlying control flow event.

## Syntax

*Go Syntax*

```text
// ASiCSignerNotificationEventArgs carries the ASiCSigner Notification event's parameters.
type ASiCSignerNotificationEventArgs struct {...}

func (args *ASiCSignerNotificationEventArgs) EventID() string
func (args *ASiCSignerNotificationEventArgs) EventParam() string
// ASiCSignerNotificationEvent defines the signature of the ASiCSigner Notification event's handler function.
type ASiCSignerNotificationEvent func(sender *ASiCSigner, args *ASiCSignerNotificationEventArgs)

func (obj *ASiCSigner) GetOnNotificationHandler() ASiCSignerNotificationEvent
func (obj *ASiCSigner) SetOnNotificationHandler(handlerFunc ASiCSignerNotificationEvent)
```

## Remarks

The struct fires this event to let the application know about some event, occurrence, or milestone in the struct. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the *EventID* parameter. *EventParam* contains any parameters accompanying the occurrence. Depending on the type of the struct, the exact action it is performing, or the document being processed, one or both may be omitted.

This struct can fire this event with the following *EventID* values:

|  |  |
| --- | --- |
| AddReference | A reference is being added to the archive. The EventParam parameter contains the path. Use the event handler to tune-up the reference parameters. One such parameter, represented by the RefMimeType config property, is the MIME type of the referenced file object. |
| AddDataObjectFormat | TBD |
| AddXMLReference | TBD |
| ContainerLoaded | Notifies the application that the ASiC container has been loaded. This is a backward-compatibility-only notification: use OnContainerLoaded event instead. |
| RetrieveQualifyingProperties | TBD |
| BeforeTimestamp | This event is fired before a timestamp is requested from the timestamping authority. Use the event handler to modify TSA and HTTP settings. |
| TimestampError | This event is only fired if the struct failed to obtain a timestamp from the timestamping authority. The EventParam parameter contains extended error info. |
| TimestampRequest | A timestamp is requested from the custom timestamping authority. This event is only fired if [TimestampServer](#timestampserver-property-asicsigner-component) was set to a virtual:// URI. The EventParam parameter contains the TSP request (or the plain hash, depending on the value provided to [TimestampServer](#timestampserver-property-asicsigner-component)), in base16, that needs to be sent to the TSA. Use the event handler to send the request to the TSA. Upon receiving the response, assign it, in base16, to the TimestampResponse configuration property. |

# SignatureFound Event ([ASiCSigner](#asicsigner-component) Component)

Signifies the start of signature validation.

## Syntax

*Go Syntax*

```text
// ASiCSignerSignatureFoundEventArgs carries the ASiCSigner SignatureFound event's parameters.
type ASiCSignerSignatureFoundEventArgs struct {...}

func (args *ASiCSignerSignatureFoundEventArgs) Index() int32
func (args *ASiCSignerSignatureFoundEventArgs) EntityLabel() string
func (args *ASiCSignerSignatureFoundEventArgs) IssuerRDN() string
func (args *ASiCSignerSignatureFoundEventArgs) SerialNumber() []byte
func (args *ASiCSignerSignatureFoundEventArgs) SubjectKeyID() []byte
func (args *ASiCSignerSignatureFoundEventArgs) CertFound() bool
func (args *ASiCSignerSignatureFoundEventArgs) ValidateSignature() bool
func (args *ASiCSignerSignatureFoundEventArgs) SetValidateSignature(value bool)

func (args *ASiCSignerSignatureFoundEventArgs) ValidateChain() bool
func (args *ASiCSignerSignatureFoundEventArgs) SetValidateChain(value bool)

// ASiCSignerSignatureFoundEvent defines the signature of the ASiCSigner SignatureFound event's handler function.
type ASiCSignerSignatureFoundEvent func(sender *ASiCSigner, args *ASiCSignerSignatureFoundEventArgs)

func (obj *ASiCSigner) GetOnSignatureFoundHandler() ASiCSignerSignatureFoundEvent
func (obj *ASiCSigner) SetOnSignatureFoundHandler(handlerFunc ASiCSignerSignatureFoundEvent)
```

## Remarks

This event tells the application that signature validation is about to start, and provides the details about the signer's certificate via its *IssuerRDN*, *SerialNumber*, and *SubjectKeyID* parameters. It fires for every signature located in the verified document or message.

The *CertFound* parameter is set to True if the struct has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the KnownCertificates property.

Signature validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the  and  properties respectively.

Use the *ValidateSignature* and *ValidateChain* parameters to tell the verifier which stages to include in the validation.

# SignatureValidated Event ([ASiCSigner](#asicsigner-component) Component)

Marks the completion of the signature validation routine.

## Syntax

*Go Syntax*

```text
// ASiCSignerSignatureValidatedEventArgs carries the ASiCSigner SignatureValidated event's parameters.

func (obj *ASiCSigner) GetOnSignatureValidatedHandler() ASiCSignerSignatureValidatedEvent
func (obj *ASiCSigner) SetOnSignatureValidatedHandler(handlerFunc ASiCSignerSignatureValidatedEvent)
```

## Remarks

This event is fired upon the completion of the signature validation routine, and reports the respective validation result.

Use the *IssuerRDN*, *SerialNumber*, and/or *SubjectKeyID* parameters to identify the signing certificate.

*ValidationResult* is set to 0 if the validation has been successful, or to a non-zero value in case of a validation failure.

|  |  |  |
| --- | --- | --- |
| svtValid | 0 | The signature is valid |
| svtUnknown | 1 | Signature validity is unknown |
| svtCorrupted | 2 | The signature is corrupted |
| svtSignerNotFound | 3 | Failed to acquire the signing certificate. The signature cannot be validated. |
| svtFailure | 4 | General failure |
| svtReferenceCorrupted | 5 | Reference corrupted (XML-based signatures only) |

# TimestampFound Event ([ASiCSigner](#asicsigner-component) Component)

func (obj *ASiCSigner) GetOnTimestampFoundHandler() ASiCSignerTimestampFoundEvent
func (obj *ASiCSigner) SetOnTimestampFoundHandler(handlerFunc ASiCSignerTimestampFoundEvent)
```

## Remarks

This event fires for every timestamp identified during signature processing, and reports the details about the signer's certificate via its *IssuerRDN*, *SerialNumber*, and *SubjectKeyID* parameters.

The *CertFound* parameter is set to True if the struct has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the KnownCertificates property.

Just like with signature validation, timestamp validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the  and  properties respectively.

Use the *ValidateSignature* and *ValidateChain* parameters to tell the verifier which stages to include in the validation.

# TimestampRequest Event ([ASiCSigner](#asicsigner-component) Component)

Fires when the class is ready to request a timestamp from an external TSA.

## Syntax

*Go Syntax*

```text
// ASiCSignerTimestampRequestEventArgs carries the ASiCSigner TimestampRequest event's parameters.
type ASiCSignerTimestampRequestEventArgs struct {...}

func (args *ASiCSignerTimestampRequestEventArgs) TSA() string
func (args *ASiCSignerTimestampRequestEventArgs) TimestampRequest() string

func (obj *ASiCSigner) GetOnTimestampRequestHandler() ASiCSignerTimestampRequestEvent
func (obj *ASiCSigner) SetOnTimestampRequestHandler(handlerFunc ASiCSignerTimestampRequestEvent)
```

## Remarks

Subscribe to this event to intercept timestamp requests. You can use it to override timestamping requests and perform them in your code.

The *TSA* parameter indicates the timestamping service being used. It matches the value passed to the [TimestampServer](#timestampserver-property-asicsigner-component) property. Set the *SuppressDefault* parameter to true if you would like to stop the built-in TSA request from going ahead. The built-in TSA request is also not performed if the returned *TimestampResponse* parameter is not empty.

# TimestampValidated Event ([ASiCSigner](#asicsigner-component) Component)

# TLSCertNeeded Event ([ASiCSigner](#asicsigner-component) Component)

Fires when a remote TLS party requests a client certificate.

## Syntax

*Go Syntax*

```text
// ASiCSignerTLSCertNeededEventArgs carries the ASiCSigner TLSCertNeeded event's parameters.
type ASiCSignerTLSCertNeededEventArgs struct {...}

func (args *ASiCSignerTLSCertNeededEventArgs) Host() string

func (obj *ASiCSigner) GetOnTLSCertNeededHandler() ASiCSignerTLSCertNeededEvent
func (obj *ASiCSigner) SetOnTLSCertNeededHandler(handlerFunc ASiCSignerTLSCertNeededEvent)
```

## Remarks

This event fires to notify the implementation that a remote TLS server has requested a client certificate. The *Host* parameter identifies the host that makes a request, and the *CANames* parameter (optional, according to the TLS spec) advises on the accepted issuing CAs.

Use the TLSClientChain property in response to this event to provide the requested certificate. Please make sure the client certificate includes the associated private key. Note that you may set the certificates before the connection without waiting for this event to fire.

This event is preceded by the [TLSHandshake](#tlshandshake-event-asicsigner-component) event for the given host and, if the certificate was accepted, succeeded by the [TLSEstablished](#tlsestablished-event-asicsigner-component) event.

# TLSCertValidate Event ([ASiCSigner](#asicsigner-component) Component)

This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.

This event is fired during a TLS handshake. Use the TLSServerChain property to access the certificate chain. In general, structs may contact a number of TLS endpoints during their work, depending on their configuration.

*Accept* is assigned in accordance with the outcome of the internal validation check performed by the struct, and can be adjusted if needed.

# TLSEstablished Event ([ASiCSigner](#asicsigner-component) Component)

Fires when a TLS handshake with Host successfully completes.

## Syntax

*Go Syntax*

```text
// ASiCSignerTLSEstablishedEventArgs carries the ASiCSigner TLSEstablished event's parameters.
type ASiCSignerTLSEstablishedEventArgs struct {...}

func (args *ASiCSignerTLSEstablishedEventArgs) Host() string
func (args *ASiCSignerTLSEstablishedEventArgs) Version() string
func (args *ASiCSignerTLSEstablishedEventArgs) Ciphersuite() string
func (args *ASiCSignerTLSEstablishedEventArgs) ConnectionId() []byte
func (args *ASiCSignerTLSEstablishedEventArgs) Abort() bool
func (args *ASiCSignerTLSEstablishedEventArgs) SetAbort(value bool)

// ASiCSignerTLSEstablishedEvent defines the signature of the ASiCSigner TLSEstablished event's handler function.
type ASiCSignerTLSEstablishedEvent func(sender *ASiCSigner, args *ASiCSignerTLSEstablishedEventArgs)

func (obj *ASiCSigner) GetOnTLSEstablishedHandler() ASiCSignerTLSEstablishedEvent
func (obj *ASiCSigner) SetOnTLSEstablishedHandler(handlerFunc ASiCSignerTLSEstablishedEvent)
```

## Remarks

The struct uses this event to notify the application about a successful completion of a TLS handshake.

The *Version*, *Ciphersuite*, and *ConnectionId* parameters indicate the security parameters of the new connection. Use the *Abort* parameter if you need to terminate the connection at this stage.

# TLSHandshake Event ([ASiCSigner](#asicsigner-component) Component)

Fires when a new TLS handshake is initiated, before the handshake commences.

## Syntax

*Go Syntax*

```text
// ASiCSignerTLSHandshakeEventArgs carries the ASiCSigner TLSHandshake event's parameters.
type ASiCSignerTLSHandshakeEventArgs struct {...}

func (args *ASiCSignerTLSHandshakeEventArgs) Host() string
func (args *ASiCSignerTLSHandshakeEventArgs) Abort() bool
func (args *ASiCSignerTLSHandshakeEventArgs) SetAbort(value bool)

// ASiCSignerTLSHandshakeEvent defines the signature of the ASiCSigner TLSHandshake event's handler function.
type ASiCSignerTLSHandshakeEvent func(sender *ASiCSigner, args *ASiCSignerTLSHandshakeEventArgs)

func (obj *ASiCSigner) GetOnTLSHandshakeHandler() ASiCSignerTLSHandshakeEvent
func (obj *ASiCSigner) SetOnTLSHandshakeHandler(handlerFunc ASiCSignerTLSHandshakeEvent)
```

## Remarks

The struct uses this event to notify the application about the start of a new TLS handshake to *Host*. If the handshake is successful, this event will be followed by the [TLSEstablished](#tlsestablished-event-asicsigner-component) event. If the server chooses to request a client certificate, the [TLSCertNeeded](#tlscertneeded-event-asicsigner-component) event will also be fired.

# TLSShutdown Event ([ASiCSigner](#asicsigner-component) Component)

Reports the graceful closure of a TLS connection.

## Syntax

*Go Syntax*

```text
// ASiCSignerTLSShutdownEventArgs carries the ASiCSigner TLSShutdown event's parameters.
type ASiCSignerTLSShutdownEventArgs struct {...}

func (args *ASiCSignerTLSShutdownEventArgs) Host() string
// ASiCSignerTLSShutdownEvent defines the signature of the ASiCSigner TLSShutdown event's handler function.
type ASiCSignerTLSShutdownEvent func(sender *ASiCSigner, args *ASiCSignerTLSShutdownEventArgs)

func (obj *ASiCSigner) GetOnTLSShutdownHandler() ASiCSignerTLSShutdownEvent
func (obj *ASiCSigner) SetOnTLSShutdownHandler(handlerFunc ASiCSignerTLSShutdownEvent)
```

## Remarks

This event notifies the application about the closure of an earlier established TLS connection. Note that only graceful connection closures are reported.

# Config Settings ([ASiCSigner](#asicsigner-component) Component)

 The struct accepts one or more of the following *configuration settings*. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, access to these *internal properties* is provided through the [Config](#config-method-asicsigner-component) method.

### ASiCSigner Config Settings

**AddAllDataObjectsTimestamp**: Whether to add all data objects timestamp during signing.If this property is set to True, the all data objects timestamp (xades:AllDataObjectsTimeStamp element) will be added.

**ASiCOptions**: Specifies the ASiC options.Contains a comma-separated list of values that specifies ASiC options.

Supported values are:

|  |  |  |
| --- | --- | --- |
| UseP7MExtensionForExtendedCAdES |  | When this flag is set, the *.p7m extension is used for extended CAdES signatures inside the container. Otherwise, the *.p7s extension is used. |
| EncodeIRI |  | When this flag is set, non-ASCII characters in filenames are encoded as defined in RFC 3987 when used in XML signature or manifest. |

**AsyncDocumentID**: Specifies the document ID for SignAsyncEnd() call.Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch. This value helps ASiCSigner identify the correct signature in the returned batch of responses. If using batched requests, make sure to set this property to the same value on both pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

**CachedCRLMaxAge**: Specifies the maximum age of a cached CRL.Use this setting to specify the maximum number of seconds that may pass since a CRL was added to the global cache. When the cached CRL is older than this value, it is disregarded and a new CRL should be fetched.

The default value is 1 day (86400 seconds). A value of 0 disables the absolute CRL age check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

**CachedCRLMaxAgeRatio**: Specifies the maximum age of a cached CRL as a percentage of its remaining lifetime.Use this setting to specify the percentage of the CRL's remaining lifetime, measured from the time the CRL was added to the global cache to the CRL's NextUpdate. When this portion of the remaining lifetime has passed, the cached CRL is disregarded and a new CRL should be fetched.

The default value is 50 percent. Values are interpreted in the 0..100 range. A value of 0 disables the CRL ratio check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

**CachedCRLOverlapTime**: Specifies the time period before a cached CRL's NextUpdate when it is considered stale and must be refreshed.Use this setting to specify the number of seconds before the NextUpdate time at which the cached CRL should be disregarded, and a new CRL should be fetched.

The default value is 10 minutes (600 seconds). A value of 0 disables the CRL overlap check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

This setting is evaluated independently from [CachedCRLMaxAge](#CachedCRLMaxAge) and [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio). If several cached CRL freshness settings are enabled, the cached CRL is used only if it satisfies all of them.

**CachedOCSPResponseMaxAge**: Specifies the maximum age of a cached OCSP response.Use this setting to specify the maximum number of seconds that may pass since an OCSP response was added to the global cache. When the cached OCSP response is older than this value, it is disregarded and a new OCSP response should be fetched.

The default value is 1 hour (3600 seconds). A value of 0 disables the absolute OCSP response age check. This setting is also used to limit open-ended OCSP responses that do not have NextUpdate. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

**CachedOCSPResponseMaxAgeRatio**: Specifies the maximum age of a cached OCSP response as a percentage of its remaining lifetime.Use this setting to specify the percentage of the OCSP response's remaining lifetime, measured from the time the OCSP response was added to the global cache to the response's NextUpdate. When this portion of the remaining lifetime has passed, the cached OCSP response is disregarded and a new OCSP response should be fetched.

The default value is 50 percent. Values are interpreted in the 0..100 range. Open-ended OCSP responses without NextUpdate ignore this setting; use [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge) to limit their age. A value of 0 disables the OCSP response ratio check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

**CachedOCSPResponseOverlapTime**: Specifies the time period before a cached OCSP response's NextUpdate when it is considered stale and must be refreshed.Use this setting to specify the number of seconds before the NextUpdate time at which the cached OCSP response should be disregarded, and a new OCSP response should be fetched.

The default value is 10 minutes (600 seconds). A value of 0 disables the OCSP response overlap check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

This setting is evaluated independently from [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge) and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio). If several cached OCSP response freshness settings are enabled, the cached OCSP response is used only if it satisfies all of them.

The final result will be published in the ChainValidationResult property once the validation process completes.

**CheckValidityPeriodForTrusted**: Whether to check validity period for trusted certificates.Whether to check validity period for trusted certificates.

**ClaimedRolesXML**: The XML content of the claimed roles.Use this property to get/specify the XML content of the claimed roles element.

**ClaimedRoleText**: The text of the claimed role.Use this property to get/specify the text of the first claimed role.

**CmsOptAnnexKArchiveTimestampV2Mode**: Toggles use of Annex K method of calculating validation timestamp hashes.This CMS message option toggles the use of Annex K method of calculating validation timestamp hashes. Switch this option off to stick to RFC5126 p6.3.5 method.

**CmsOptCheckATSHashIndexElements**: Enables extra checks when processing ATSHashIndex attribute.This CMS message option enables an extra check to make sure every hash in ATSHashIndex has an associated CMS element.

**CmsOptCompareRDNAsStrings**: Enforces comparison of RDN elements as text strings, rather than their byte encodings.This CMS message option enforces comparison of string RDN elements as text strings rather than their original byte encodings.

**CmsOptDEREncodeContentForATSv2**: Enables DER encoding for ATSv2 hashed content.This is an outdated setting, which reflects a complicated (at times) story of AdES infrastructure development. You are unlikely to need it.

**CmsOptDigitPADSSCompatibility**: Enables Digit PADSS compatibility mode.This CMS message option enables compatibility mode with Digit PADSS software.

**CmsOptForceSigningCertificateV2Usage**: Enforces use of signing-certificate-v2 attribute.This CMS message option enforces the use of signing-certificate-v2 attribute in favour of older signing-certificate-v1. Current regulations require that signing-certificate-v2 is used at all times.

**CmsOptIgnoreDERReqInArchiveTimestamps**: Switches off DER encoding requirement for archival timestamps.This CMS message option switches off DER encoding requirement for archival timestamps (normally meaning no attribute reordering). This setting is a workaround for certain buggy CAdES products.

**CmsOptImzagerMIMCompatibility**: Enables Imzager MIM compatibility mode.This CMS message option enables compatibility mode with Imzager MIM software.

**CmsOptIncludeCertToAttributes**: Regulates whether to include the signing certificate to the signature as the signing-certificate attribute.This CMS message option controls inclusion of the signing certificate as the signing-certificate attribute. Current regulations require that this attribute is present.

**CmsOptIncludeCertToMessage**: Regulates whether to include the signing certificate and its chain to the CMS.This CMS message option controls inclusion of the signing certificate to the CMS structure. It is recommended that the certificate is included. Note that this option has no effect if the signature level used (e.g. XL) enforces inclusion of the certificate to the message.

**CmsOptInsertContentType**: Regulates whether the content-type time attribute should be included in the signature structure.This CMS message option specifies whether the content-type attribute should be included in the signature structure.

**CmsOptInsertMessageDigests**: Regulates whether the message-digest signed attribute should be included in the signature structure.This CMS message option controls inclusion of the message-digest attribute in the signature structure. Current regulations require that this attribute is present at all times.

**CmsOptInsertSigningTime**: Regulates whether the signing-time attribute should be included in the signature structure.This CMS message option specifies whether the signing-time attribute should be included in the signature structure. Switch it off to suppress inclusion of the signing-time attribute.

**CmsOptSkipEnvContentInfoOnSigArchival**: Excludes hashing of enveloped content when calculating an archival timestamp.This CMS message option excludes hashing of enveloped content when calculating an archival timestamp. This setting is a workaround for certain buggy CAdES products.

**CmsOptUseATSHashIndexV1**: Enables use of ATSHashIndexV1 attribute.This CMS message option enables use of deprecated ATSHashIndexV1 attribute when calculating archival timestamp V3 hashes.

**CmsOptUseATSHashIndexV3**: Enables the use of the third version of archival timestamps.Enables the use of archival timestamp v3 objects when creating long-term and archival signatures. This is the default setting. Setting it to false tells the components to stick with archival timestamps version 2.

**CmsOptUseGeneralizedTimeFormat**: Enables or disables encoding of the signing-time attribute using ASN.1 GENERALIZEDTIME type.This CMS message option controls whether the signing-time attribute should be encoded as GENERALIZEDTIME or UTCTIME. Current regulations require that the GENERALIZEDTIME type is used at all times.

**CmsOptUseGenericSigAlgorithmOIDs**: Enables use of generic signature algorithm OIDs in the signature.This CMS message option enforces the use of generic public key algorithm OIDs (e.g. rsaEncryption) instead of hash algorithm-specific variants (e.g. sha256withRsaEncryption). This setting is a workaround for certain buggy CAdES products.

**CmsOptUsePlainContentForTimestampHashes**: Makes CAdESSigner ignore ASN.1 content formatting when calculating timestamp hashes.This CMS message option causes CAdESSigner to ignore ASN.1 formatting when feeding content to timestamp hashes (might make a difference with split OCTETSTRINGs for extra long contents). This option is only applicable to content timestamps and ArchivalTimestampV1's. This setting is a workaround for certain buggy CAdES products.

**CommitmentTypeIndicationAllSignedDataObjects[Index]**: Specifies the CommitmentTypeIndication's AllSignedDataObjects.This property contains if the CommitmentTypeIndication's AllSignedDataObjects element is present that indicates that all the signed data objects share the same commitment. Index value could be omitted for the first CommitmentTypeIndication element.

Index value could be omitted for the first CommitmentTypeIndication element.

**CommitmentTypeIndicationObjectReference[Index]**: Specifies the CommitmentTypeIndication's ObjectReference.This property contains the CommitmentTypeIndication's ObjectReference elements that refer to one or several ds:Reference elements of the ds:SignedInfo corresponding with one data object qualified by this property. Index value could be omitted for the first CommitmentTypeIndication element.

**CommitmentTypeIndicationQualifiersXML[Index]**: The XML content of the CommitmentTypeIndication's Qualifiers.This property contains the CommitmentTypeIndication's Qualifiers elements XML content. Index value could be omitted for the first CommitmentTypeIndication element.

**ContentType**: Specifies the content-type of the container.This property represents the "/mimetype" service entry of the container. For ASiC-S the "application/vnd.etsi.asic-s+zip" content-type or the original content-type of the archived document are allowed. For ASiC-E, only the "application/vnd.etsi.asic-e+zip" is allowed.

**CustomTrustedLists**: Specifies the custom TrustedLists.Use this property to specify the custom TSLs (Trust Service status Lists) to the validator. The URLs list is comma-separated.

**CustomTSLs**: Specifies the custom TrustedLists.Use this property to specify the custom TSLs (Trust Service status Lists) to the validator. The URLs list is comma-separated.

Index value could be omitted for the first DataObjectFormat element.

**DataObjectFormatObjectReference[Index]**: Specifies the DataObjectFormat's ObjectReference.This property contains the DataObjectFormat's ObjectReference element that reference the ds:Reference element of the ds:Signature corresponding with the data object qualified by this property.

For example, if the corresponding ds:Reference element has an Id "reference-id-1", then you should set this property to "#reference-id-1" value.

Index value could be omitted for the first DataObjectFormat element.

**DeltaCRLPreference**: Specifies whether complete or delta CRLs are preferred.Use this setting to specify which CRL type should be preferred during revocation checks performed by the AdES component.

The default value is **dcrlpPreferComplete** (1).

Supported values:

- **dcrlpPreferDelta** (0): retrieve and use delta CRLs when available, falling back to complete CRLs when needed.
- **dcrlpPreferComplete** (1): try complete CRLs first, and use delta CRLs only if complete CRLs cannot be retrieved.

**DislikeOpenEndedOCSPs**: Tells the struct to discourage OCSP responses without an explicit NextUpdate parameter.When this property is set to True, the validation engine treats OCSP response without a NextUpdate field as 'substandard' and tries to obtain some further revocation material for the certificate in question (a different OCSP or a CRL, even if the struct is configured to prefer the OCSP route). This is to work around Adobe Reader's intolerance to such OCSPs when classifying signed documents as LTV (as of August 2022).

**EvaluateSystemTrust**: Enables or disables usage of the platform's built-in trust validation facilities.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms). This functionality is currently available on macOS and iOS systems only. This property is disabled by default, because enabling it may prevent the AdES components from collecting full revocation information required for long-term validation (LTV) signatures.

**EvaluateSystemTrustForSelfSignedCertificates**: Enables or disables usage of the platform's built-in trust validation facilities for self-signed certificates.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms) for self-signed certificates. This functionality is currently available on macOS and iOS systems only. This property is enabled by default.

**EvaluateSystemTrustForSSL**: Enables or disables usage of the platform's built-in trust validation facilities for SSL/TLS.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms) specifically for SSL/TLS certificates. This functionality is currently available on macOS and iOS systems only. This property is enabled by default.

**ExclusiveCanonicalizationPrefix**: Specifies the exclusive canonicalization prefix.Specifies the prefix for the ec:InclusiveNamespaces element for the exclusive canonicalization.

Default value is "ec". In this case "ec:" prefix will be used.

Special values:

|  |  |
| --- | --- |
| "#default" or "" | indicates that the prefix will be omitted. |
| "#auto" | indicates that the prefix will be auto-detected based on the parent nodes. |

**ForceCompleteChainValidation**: Whether to check the CA certificates when the signing certificate is invalid.Set this property to True to check issuer (CA) certificates if the signing or an intermediate chain certificate is invalid.

**ForceCompleteChainValidationForTrusted**: Whether to continue with the full validation up to the root CA certificate for mid-level trust anchors. Set this property to True to enable full chain validation for explicitly trusted intermediary or end-entity certificates. This may be useful when creating signatures to enforce completeness of the collected revocation information. It often makes sense to set this property to false when validating signatures to reduce validation time and avoid issues with badly configured environments.

**GenerateMetaInfEntry**: Specifies whether the directory META-INF entry should be generated.Set this property to False to suppress generation of the directory META-INF entry in the container/archive.

Note: ETSI ASiC Conformance Checker dislikes archives with the directory META-INF entry.

**GracePeriod**: Specifies a grace period to apply during revocation information checks.Use this property to specify a grace period (in seconds). Grace period applies to certain subprotocols, such as OCSP, and caters to the inaccuracy and/or missynchronization of clocks on different participating systems. Any time deviations within the grace period will be tolerated.

**HMACKey**: The key value for HMAC.Use this property to set the HMAC key. The component uses base16 (hex) encoding for this configuration value.

**HMACOutputLength**: Sets the length of the HMAC output.Use this property to configure the length of the HMAC output, in bytes.

**HMACSigningUsed**: Whether to use HMAC signing.Set this property to true to make the component perform signing using HMAC method, rather than asymmetric cryptography. TBD

**IgnoreChainLoops**: Whether chain loops should be ignored.Set this property to True to make the validation engine ignore chain loops. This may be an option when you need to process chains from buggy CAs that happen to include subchains that sign themselves.

**IgnoreChainValidationErrors**: Whether to ignore any certificate chain validation issues.Enable this property to ignore any chain validation errors when creating a signature. This may be useful if the signature is created in an environment which uses different trust settings to the validation environment.

**IgnoreOCSPNoCheckExtension**: Whether the OCSP NoCheck extension should be ignored.Set this property to True to make the validation engine ignore the OCSP no-check extension. You would normally need to set this property when validating severely non-compliant chains that misuse the extension, causing chain loops or other validation issues.

**IgnoreSystemTrust**: Whether trusted Windows Certificate Stores should be treated as trusted.Specifies whether, during chain validation, the struct should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the struct should trust the certificates residing in the Trusted Root Certification Authorities store.

If [IgnoreSystemTrust](#IgnoreSystemTrust) is True, certificates residing in the trusted root store are treated as if they are known, rather than trusted. Only certificates provided via other means (such as the TrustedCertificates property) are considered trusted.

**IgnoreTimestampFailure**: Whether to ignore time-stamping failure during signing.If this property is set to True, any failure during time-stamping process will be ignored.

**ImplicitlyTrustSelfSignedCertificates**: Whether to trust self-signed certificates. Set this property to True to implicitly trust all self-signed certificates. Use it with care as trusting just about every self-signed certificate is unwise. One exceptional reason where this property may be handy is where a chain is validated in an environment that is not supposed to trust it (for example, a signing, rather than verifying environment, or a QA server). Trusting all self-signing certificates (which are normally trusted) allows emulating the verifying environment without actually changing its security settings.

**IncludeKnownRevocationInfoToSignature**: Whether to include custom revocation info to the signature.This property specifies whether revocation pieces provided via KnownCertificates, KnownCRLs, and KnownOCSPs properties should be included into the signature. This property lets you include custom validation elements to the signature in addition to the ones comprising the signing chain.

**InclusiveNamespacesPrefixList**: Specifies the InclusiveNamespaces PrefixList.Use this property to read/specify InclusiveNamespaces PrefixList for exclusive canonicalization transform of SignedInfo element. See XML-Signature Syntax and Processing specification for details.

**KeyInfoID**: Specifies the ID for KeyInfo element.This property contains the identifier (ID) attribute of the ds:KeyInfo element.

**KeyName**: Contains information about the key used for signing.The KeyName element contains a string value (with significant whitespaces) which may be used by the signer to communicate a key identifier to the recipient. Typically, the KeyName element contains an identifier related to the key pair used to sign the message, but it may contain other protocol-related information that indirectly identifies a key pair. Common uses of the KeyName include simple string names for keys, a key index, a distinguished name (DN), an email address, etc.

**ManifestHandlingMode**: The approach to use manifest conflict resolution.This setting specifies the conflict resolution approach to use when generating or updating manifests when re-signing containers. The following options are available:

- *always*: always generate a new manifest
- *never*: never generate a new manifest
- *diff*: a manifest is only added if the existing manifest does not referenced all the files covered by the new signature (i.e. if new files were added during re-signing).
- *auto* or an empty string: the default behavior, which currently maps to *always*

**Overwrite**: Forcefully overwrite OutputFile if it exists.Enable this setting to make the component overwrite the specified output file if it already exists on disk. This setting only applies to the ASiC output (the OutputFile property) and not to extracted archived files. Use the OnFileExtractionStart event to control overwriting behaviour for extracted files.

**PolicyDescription**: signature policy description.This property specifies the Description of the signature policy.

**PolicyExplicitText**: The explicit text of the user notice.Use this property to specify the explicit text of the user notice to be displayed when the signature is verified.

**PolicyUNNumbers**: The noticeNumbers part of the NoticeReference CAdES attribute. Defines the "noticeNumbers" part of the NoticeReference signature policy qualifier for CAdES-EPES.

**PolicyUNOrganization**: The organization part of the NoticeReference qualifier.Defines the "organization" part of the NoticeReference signature policy qualifier for CAdES-EPES.

**ProductionPlace**: Identifies the place of the signature production.The signature production place in JSON format that was included or to be included into the signature.

Sample value: '{"addressCountry": "UK", "addressLocality": "London", "postalCode": "N1 7GU", "streetAddress": "20-22 Wenlock Road"}'

**PromoteLongOCSPResponses**: Whether long OCSP responses are requested. Set this property to True to force the struct to publish the 'long' form of OCSP responses. Otherwise, only BasicOCSPResponse blobs are promoted.

**PSSUsed**: Whether to use RSASSA-PSS algorithm.Although the RSASSA-PSS algorithm provides better security than a classic RSA scheme (PKCS#1-1.5), please take into account that RSASSA-PSS is a relatively new algorithm which may not be understood by older implementations. This is an alias for *UsePSS*.

**QualifyingPropertiesID**: Specifies the ID for QualifyingProperties element.This property contains the identifier (ID) attribute of the xades:QualifyingProperties element.

**QualifyingPropertiesObjectID**: Specifies the ID for object with QualifyingProperties element.This property contains the identifier (ID) attribute of the ds:Object element that contains xades:QualifyingProperties element.

**QualifyingPropertiesReferenceCount**: The number of the QualifyingPropertiesReference elements.Returns the number of the xades:QualifyingPropertiesReference elements available.

**QualifyingPropertiesReferenceID[Index]**: Specifies the QualifyingPropertiesReference's ID.This property contains an identifier (ID) attribute of the xades:QualifyingPropertiesReference element. Index value could be omitted for the first QualifyingPropertiesReference element.

**QualifyingPropertiesReferenceURI[Index]**: Specifies the QualifyingPropertiesReference's URI.This property contains an URI attribute of the xades:QualifyingPropertiesReference element. Index value could be omitted for the first QualifyingPropertiesReference element.

**RefHashAlgorithm**: Specifies the hash algorithm for references.Use this property to specify the reference's hash algorithm.

The default value is empty string, in this case, the hash algorithm specified in HashAlgorithm property is used.

**RefMimeType**: Specifies the MIME type to apply to the processed file.Assign this property with the MIME type to apply to the processed file reference, for example *application/vnd.openxmlformats-officedocument.wordprocessingml.document*.

To set different mime types for more than one file, subscribe to [Notification](#notification-event-asicsigner-component) event and handle the *AddReference* event, where you can provide a separate MIME type for every reference.

**RefsTimestampType**: Specifies references timestamp type to include to the signature.Contains a comma-separated list of values that specifies which references timestamp type to include to the signature when signature upgraded to XAdES-X or XAdES-E-X form.

Supported values are:

|  |  |  |
| --- | --- | --- |
| SigAndRefs |  | SigAndRefs timestamp |
| RefsOnly |  | RefsOnly timestamp |

**RevocationCacheAgePolicy**: Specifies a preset policy for cached CRL and OCSP response freshness settings.Use this setting to configure all cached revocation freshness settings at once. The default value is Default.

Supported values are case-insensitive:

|  |  |
| --- | --- |
| Default | Applies the AdES default freshness settings: crl:86400;50;600,ocsp:3600;50;600. This means: CRL maximum age 1 day, CRL age ratio 50%, CRL overlap 10 minutes; OCSP response maximum age 1 hour, OCSP response age ratio 50%, OCSP response overlap 10 minutes. This value is the default. |
| Disabled | Sets [CachedCRLOverlapTime](#CachedCRLOverlapTime), [CachedOCSPResponseOverlapTime](#CachedOCSPResponseOverlapTime), [CachedCRLMaxAge](#CachedCRLMaxAge), [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge), [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio), and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio) to 0. It only disables the cache-age freshness policy; it does not disable revocation checking or use of the revocation cache. |
| Short | Uses crl:43200;50;300,ocsp:1800;50;300. This means: CRL maximum age 12 hours, CRL age ratio 50%, CRL overlap 5 minutes; OCSP response maximum age 30 minutes, OCSP response age ratio 50%, OCSP response overlap 5 minutes. |
| Long | Uses crl:518400;50;3600,ocsp:21600;50;3600. This means: CRL maximum age 6 days, CRL age ratio 50%, CRL overlap 1 hour; OCSP response maximum age 6 hours, OCSP response age ratio 50%, OCSP response overlap 1 hour. |
| N | Interprets N as an integer number of seconds. The overlap settings are set to N seconds, CRL maximum age is set to N * 144, OCSP response maximum age is set to N * 6, and both ratio settings are set to 50. |
| crl:<maxAge>;<ratio>;<overlap>,ocsp:<maxAge>;<ratio>;<overlap> | Sets the CRL and OCSP response freshness values explicitly. |

Ratios must be in the 0..100 range. Maximum age and overlap values must be non-negative. Short and Long are time-scale profiles: Long allows older cached revocation information by increasing maximum ages, but also uses a larger pre-expiry safety margin by increasing overlap times. For individual [CachedCRLOverlapTime](#CachedCRLOverlapTime), [CachedOCSPResponseOverlapTime](#CachedOCSPResponseOverlapTime), [CachedCRLMaxAge](#CachedCRLMaxAge), [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge), [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio), and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio) settings, a value of 0 disables the corresponding freshness check.

This allows the system to persistently save and retrieve PKI cache data, even across application restarts.

The default value is an empty string - no cached PKI data is stored on disk.

Example:

```text
PKICachePath=C:\Temp\cache
```

 In this example, the cached PKI data is stored in the C:\Temp\cache directory.

**ProductVersion**: Returns the version of the SecureBlackbox library.This property returns the long version string of the SecureBlackbox library being used (major.minor.build.revision).

**ServerSSLDHKeyLength**: Sets the size of the TLS DHE key exchange group.Use this property to adjust the length, in bits, of the DHE prime to be used by the TLS server.

**StaticDNS**: Specifies whether static DNS rules should be used.Set this property to enable or disable static DNS rules for the struct. Works only if *UseOwnDNSResolver* is set to *true*.

Supported values are:

|  |  |  |
| --- | --- | --- |
| none |  | No static DNS rules (default) |
| local |  | Local static DNS rules |
| global |  | Global static DNS rules |

**StaticIPAddress[domain]**: Gets or sets an IP address for the specified domain name.Use this property to get or set an IP address for the specified domain name in the internal (of the struct) or global DNS rules storage depending on the *StaticDNS* value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are divided by the | (pipe) character.

**StaticIPAddresses**: Gets or sets all the static DNS rules.Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If *StaticDNS* of the struct is set to "*local*", the property returns/restores the rules from/to the internal storage of the struct. If *StaticDNS* of the struct is set to "*global*", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

**Tag**: Allows to store any custom data.Use this config property to store any custom data.

**TLSSessionGroup**: Specifies the group name of TLS sessions to be used for session resumption.Use this property to limit the search of cached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the structs.

**TLSSessionLifetime**: Specifies lifetime in seconds of the cached TLS session.Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

**TLSSessionPurgeInterval**: Specifies how often the session cache should remove the expired TLS sessions.Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

**UseCRLObjectCaching**: Specifies whether reuse of loaded CRL objects is enabled.This setting enables or disables the caching of CRL objects. When set to true (the default value), the system checks if a CRL object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where CRL objects are frequently used.

**UseInternalRandom**: Switches between SecureBlackbox-own and platform PRNGs.Allows to switch between internal/native PRNG implementation and the one provided by the platform.

**UseLegacyAdESValidation**: Enables legacy AdES validation mode.Use this setting to switch the AdES component to the validation approach that was used in SBB 2020/SBB 2022 (less attention to temporal details).

**UseOCSPResponseObjectCaching**: Specifies whether reuse of loaded OCSP response objects is enabled.This setting enables or disables the caching of OCSP response objects. When set to true (the default value), the system checks if a OCSP response object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where OCSP response objects are frequently used.

**UseOwnDNSResolver**: Specifies whether the client components should use own DNS resolver.Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

**UseSharedSystemStorages**: Specifies whether the validation engine should use a global per-process copy of the system certificate stores.Set this global property to false to make each validation run use its own copy of system certificate stores.

**UseSystemNativeSizeCalculation**: An internal CryptoAPI access tweak.This is an internal setting. Please do not use it unless instructed by the support team.

**UseSystemOAEPAndPSS**: Enforces or disables the use of system-driven RSA OAEP and PSS computations.This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

**UseSystemRandom**: Enables or disables the use of the OS PRNG.Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

**XMLRDNDescriptorName[OID]**: Defines an OID mapping to descriptor names for the certificate's IssuerRDN or SubjectRDN.This property defines custom mappings between Object Identifiers (OIDs) and descriptor names. This mapping specifies how the certificate's issuer and subject information (ds:IssuerRDN and ds:SubjectRDN elements respectively) are represented in XML signatures.

The property accepts comma-separated values where the first descriptor name is used when the OID is mapped, and subsequent values act as aliases for parsing.

Syntax:

```text
Config("XMLRDNDescriptorName[OID]=PrimaryName,Alias1,Alias2");
```

Where:

OID: The Object Identifier from the certificate's IssuerRDN or SubjectRDN that you want to map.

PrimaryName: The main descriptor name used in the XML signature when the OID is encountered.

Alias1, Alias2, ...: Optional alternative names recognized during parsing.

Usage Examples:

Map OID 2.5.4.5 to SERIALNUMBER:

```text
Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER");
```

Map OID 1.2.840.113549.1.9.1 to E, with aliases EMAIL and EMAILADDRESS:

```text
Config("XMLRDNDescriptorName[1.2.840.113549.1.9.1]=E,EMAIL,EMAILADDRESS");
```

**XMLRDNDescriptorPriority[OID]**: Specifies the priority of descriptor names associated with a specific OID.This property specifies the priority of descriptor names associated with a specific OID that allows to reorder descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during signing.

**XMLRDNDescriptorReverseOrder**: Specifies whether to reverse the order of descriptors in RDN.Specifies whether to reverse the order of descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to true (as specified in RFC 2253, 2.1).

**XMLRDNDescriptorSeparator**: Specifies the separator used between descriptors in RDN.Specifies the separator used between descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to ", " value.
