CAdESSigner Component
Properties Methods Events Config Settings Errors
The CAdESSigner component creates CAdES- and CMS-compliant electronic signatures.
Syntax
nsoftware.SecureBlackbox.CAdESSigner
Remarks
CAdESSigner can sign documents and files in compliance with CMS Advanced Electronic Signatures (CAdES) specification.
Originally developed by ETSI on the basis of PKCS#7 format and initially adopted in the European Union,
CAdES has quickly become a recognized international standard for signing all sorts of electronic documents.
CAdESSigner signer = new CAdESSigner();
signer.getNewSignature().setHashAlgorithm("SHA512"); // Default hashing algorithm SHA256
signer.getNewSignature().setLevel(CAdESSignature.aslBaselineT); // Set the level of the signature
// Select the file which will be signed
signer.setInputFile("MyExe.exe");
// Set the path where the signed file will be saved
signer.setOutputFile("signedFile.scs");
// Specify the certificate that shall be used for signing
signer.setSigningCertificate(new Certificate("cert.pfx","password"));
// Provide the address of the Time Stamping Authority (TSA) server to be used for timestamping the signature
signer.setTimestampServer("http://freetsa.org/tsr");
signer.sign(); // Sign
Besides being a signature standard in its own right, CAdES is used as part of other higher-level signature standards, such as PAdES or S/MIME. It provides a convenient framework for creating short-lived and long-term signatures over any kind of documents, and is now used by governments, healthcare providers, banks, and independent service providers all across the globe.
Standards and technologies supported
CAdESSigner offers the following signing capabilities:
- Create and upgrade CAdES signatures in accordance with the most recent CAdES specification (ETSI EN 319 122). Some features from older versions are also supported.
- All profiles are supported (BES, EPES, T, C, X, XL, A, including Baseline and Extended variants).
- Timestamping using external TSAs.
- All industry-standard cryptographic algorithms (RSA, ECDSA, SHA256-512, and many others).
Configuring the signature parameters
Configuring CAdESSigner to make it produce a signature of the right type is the main task you would need to perform in your code. Normally the service or software you will be communicating your signed documents to will provide you with the list of requirements that your signatures should match.
Typically, those will dictate the following key aspects of the signatures:
- The signature Level (such BES, T, XL, A, or XLong). This can be passed as the Level parameter of the Sign method.
- Whether the signature should be detached or enveloping: this can be adjusted via the Detached parameter of the Sign method.
- When creating a timestamped signature (such as T or A), provide the address of your online TSA service via TimestampServer property.
- When creating long-term signatures that include the signing chain and validation material, tune up validation parameters via RevocationCheck, OfflineMode, and IgnoreChainValidationErrors properties.
In some circumstances you will also need to adjust the following lower-level settings:
- Set ClaimedSigningTime to include the local signature creation time (not timestamped by a TTP).
- Specify EPES signature parameters via PolicyHash, PolicyHashAlgorithm, PolicyID, and PolicyURI properties.
- Provide the hash algorithm via the HashAlgorithm property.
Signing certificates
CAdESSigner can use certificates residing on different media. Besides generic certificates stored in PFX or PEM files (A1), it can operate with non-exportable certificates residing on hardware media (A3) or in the cloud.
Non-exportable certificates can be accessed transparently via a Windows CSP or a PKCS#11 driver, if supplied by the certificate issuer. Proprietary interfaces can be plugged in with the external signing feature (see below).
You can use CertificateManager and CertificateStorage components to access the signing certificate. Assign the certificate to SigningCertificate property, and optionally provide the remainder of its chain via SigningChain property.
Note: If signing with a non-exportable key (such as residing on a hardware device or in the cloud), please make sure you keep the original CertificateStorage object open until the signing is completed. This is because the storage component provides a 'bridge' to the private key. If the storage is closed prematurely, this bridge is destroyed, and the private key can't be used.
You don't need to provide a signing certificate or chain when timestamping and upgrading signatures, since this type of operation does not involve the signing private key.
Signing a file
Now that you have set up all signature properties and attached the signing certificate, it is time to proceed to signing. You can provide the input document in one of the following forms: as a file (assign the path to InputFile property), as a stream (assign to InputStream property), or as a byte array (assign to InputBytes). Similarly, the output can be collected in one of the same forms, either by passing the destination path or stream via OutputFile and OutputStream respectively, or by reading the resulting document bytes from the OutputBytes property after the signing completes.
Having set up the input and output (unless using OutputBytes, which should be read later), call the component's Sign method, passing the desired signature level and type as parameters. This will initiate the signing process. Depending on the settings, the signing may be as straightforward as calculating the document hash and signing it with the private key (e.g. in CAdES-BES or B-B variant), or it may involve advanced chain validation routines (CAdES-XL or -A). During the latter the component may contact a number of external revocation information sources (CRL and OCSP servers) to establish the validity of the signing certificate.
If a TSA server was provided via the TimestampServer property, the component will contact it too to timestamp the new signature.
During the signing CAdESSigner may fire events to let your code know of certain conditions. It may fire TLSCertValidate if one of the HTTP endpoints involved in the operation (which may be a CRL, OCSP, or TSA service) works over TLS and needs its certificate to be validated.
Apart from signing, CAdESSigner can perform operations on signatures of other kinds. Use Upgrade method to upgrade an existing CAdES signature to a higher level (e.g. BES to XL). Use Timestamp to add a generic or validation timestamp to an existing signature. Use the Countersign method to add a countersignature to an existing signature. For any of these operations the input should constitute a valid CAdES signature.
External signing and DCAuth
CAdESSigner, like many other components offered by the product, supports two methods of signing with external keys. These methods are fully independent of each other: you can choose the one that suits your usage scenario best.
Synchronous method: ExternalSign
This is a simpler method that basically lets you infiltrate into the heart of the signing routine by taking care of the hash signing operation. The component does the rest of the job (hash calculation, preparation of signature objects, CRL/OCSP retrieval).
To initiate this method, call SignExternal instead of Sign. When the hash is ready, it will be passed back to your code with ExternalSign event. Your event handler needs to sign the hash with the private key and return the created signature back to the component - which will embed it into the document.
You don't need your signing certificate to contain an associated private key when using this method. The certificate itself (its public copy) may be needed though, as it is often included in the hash calculation.
This method is synchronous, meaning SignExternal provides you the results immediately upon its completion.
Asynchronous method: DCAuth
DCAuth is a SecureBlackbox-own know-how technology. This protocol was designed to allow sharing of private keys across environments, allowing the signer and the private key to reside on different systems. It works in the following way:
- The signing party - such as CAdESSigner - initiates the operation using SignAsyncBegin call. This produces two outcomes: a pre-signed document (a document with a blank signature placeholder), and a request state (an object containing a hash that needs to be signed). At this point the CAdESSigner instance can be released, and the process itself terminated (which may be useful when run as part of a web page).
- The request state is passed to the private key holder party. The private key holder passes the request state to a DCAuth object, which parses the request state, extracts the hash, and signs it. The output of DCAuth processing is another object, response state, which contains the signature. The private key holder then sends the response state back to the signing party.
- The signing party re-creates the controls, and passes the response state, together with the pre-signed version of the document, to the signer's SignAsyncEnd method. SignAsyncEnd extracts the signature from the response state and incorporates it into the pre-signed document.
This method is asynchronous in that sense that, from the signing party's viewpoint, it splits the signing operation into the pre-signing and completion stages which can be performed independently from each other and in different execution contexts. This makes this method particularly helpful for use in web pages and other scenarios where the signing key is not available in real time.
Fine-grained chain validation setup
Chain validation is a sophisticated, multi-faceted procedure that involves a lot of variables. Depending on the configuration of your operating environment, the specifics of the PKI framework being used, and the validation policy you need to follow, you may want to tune up your chain validation parameters so they fit them best. A summary of such parameters is given below.
- RevocationCheck lets you choose between and/or prioritize revocation origins. OCSP sources are often preferred to CRL because of their real-time capability and the smaller size of validation tokens they produce.
- OfflineMode is a master switch that stops the component from looking for any validation tokens online. If this property is switched on, the component will only use the KnownCertificates, TrustedCertificates, KnownCRLs, and KnownOCSPs collections to look for the missing validation material.
- IgnoreChainValidationErrors makes the component ignore any major validation issues it encounters (such us an untrusted chain or missing CRL). This option is handy for debugging and for creating signatures in the environments where the signing certificate is not trusted.
- KnownCertificates, KnownCRLs, and KnownOCSPs let you provide your own validation material. This may be useful when working in OfflineMode, where the signer has no access to the validation sources, or where the validation material has already been collected.
- TrustedCertificates lets you provide a list of trust anchors, either as a complement to the system's or as an alternative to it.
- BlockedCertificates lets you provide a list of blocked/distrusted certificates. Any CA certificate contained in it will be deemed untrusted/invalid.
The following parameters are not directly related to chain validation, but may have an implicit effect on it.
- Proxy, SocketSettings, and TLSSettings let you tune up the connectivity and TLS options in accordance with local preferences.
- TLSClientChain lets you provide the client certificate and its chain for TLS client authentication.
- Subscribe to TLSCertValidate to validate any TLS certificates of the services involved in chain validation.
The results of the chain validation procedure, upon its completion, are published in the following properties:
- ChainValidationResult contains the primary result of the chain validation routine: valid, valid but untrusted, invalid, or undefined.
- ChainValidationDetails provides the details of the factors that contributed to the chain validation result, such as an outdated certificate, a missing CRL, or a missing CA certificate.
- ValidationLog contains the detailed chain validation log. The log can often be very helpful in nailing down various validation issues.

Syntax
public System.IO.Stream InputStream { get; set; }
Public Property InputStream As System.IO.Stream
Default Value
null
Remarks
Use this property to provide the data to work on. In case of the first-time signing, point this property to your data to-be-signed. If countersigning, upgrading, or timestamping an existing signature, provide a stream containing your signature.
If updating a detached signature, you might need to provide the original data via DataStream property.
The data provided via this property can alternatively be provided in a file via InputFile property.
This property is not available at design time.
KnownCertificates Property (CAdESSigner Component)
Additional certificates for chain validation.
Syntax
public CertificateList KnownCertificates { get; }
Public Property KnownCertificates As CertificateList
Remarks
Use this property to supply a list of additional certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when intermediary CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.
The purpose of the certificates to be added to this collection is roughly equivalent to that of the Intermediate Certification Authorities system store in Windows.
Do not add trust anchors or root certificates to this collection: add them to TrustedCertificates instead.
This property is not available at design time.
Please refer to the Certificate type for a complete list of fields.KnownCRLs Property (CAdESSigner Component)

Switches the component to offline mode.
Syntax
Default Value
False
Remarks
When working in offline mode, the component restricts itself from using any online revocation information sources, such as CRL or OCSP responders.
Offline mode may be useful if there is a need to verify the completeness of the validation information included within the signature or provided via KnownCertificates, KnownCRLs, and other related properties.
OutputBytes Property (CAdESSigner Component)

This property is not available at design time.
Profile Property (CAdESSigner Component)
Specifies a pre-defined profile to apply when creating the signature.
Syntax
Default Value
""
Remarks
Advanced signatures come in many variants, which are often defined by parties that needs to process them or by local standards. SecureBlackbox profiles are sets of pre-defined configurations which correspond to particular signature variants. By specifying a profile, you are pre-configuring the component to make it produce the signature that matches the configuration corresponding to that profile.
Proxy Property (CAdESSigner Component)
The proxy server settings.
Syntax
public ProxySettings Proxy { get; }
Public ReadOnly Property Proxy As ProxySettings
Remarks
Use this property to tune up the proxy server settings.
This property is read-only.
Please refer to the ProxySettings type for a complete list of fields.RevocationCheck Property (CAdESSigner Component)
Specifies the kind(s) of revocation check to perform for all chain certificates.
Syntax
public CAdESSignerRevocationChecks RevocationCheck { get; set; }
enum CAdESSignerRevocationChecks { crcNone, crcAuto, crcAllCRL, crcAllOCSP, crcAllCRLAndOCSP, crcAnyCRL, crcAnyOCSP, crcAnyCRLOrOCSP, crcAnyOCSPOrCRL }
Public Property RevocationCheck As CadessignerRevocationChecks
Enum CAdESSignerRevocationChecks crcNone crcAuto crcAllCRL crcAllOCSP crcAllCRLAndOCSP crcAnyCRL crcAnyOCSP crcAnyCRLOrOCSP crcAnyOCSPOrCRL End Enum
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.
Signatures Property (CAdESSigner Component)
Contains the list of signatures included in the CAdES signature.
Syntax
public CAdESSignatureList Signatures { get; }
Public ReadOnly Property Signatures As CAdESSignatureList

Syntax
public TimestampInfoList Timestamps { get; }
Public ReadOnly Property Timestamps As TimestampInfoList
Remarks
Use this property to access the timestamps included in the processed document.
This property is read-only and not available at design time.
Please refer to the TimestampInfo type for a complete list of fields.TimestampServer Property (CAdESSigner Component)
The address of the timestamping server.
Syntax
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 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.
TLSClientChain Property (CAdESSigner Component)
The TLS client certificate chain.
Syntax
public CertificateList TLSClientChain { get; }
Public Property TLSClientChain As CertificateList
Remarks
Assign a certificate chain to this property to enable TLS client authentication in the component. Note that the client's end-entity certificate should have a private key associated with it.
Use the CertificateStorage or CertificateManager components to import the certificate from a file, system store, or PKCS11 device.
This property is not available at design time.
Please refer to the Certificate type for a complete list of fields.TLSServerChain Property (CAdESSigner Component)
The TLS server's certificate chain.
Syntax
public CertificateList TLSServerChain { get; }
Public ReadOnly Property TLSServerChain As CertificateList
Remarks
Use this property to access the certificate chain sent by the TLS server. This property is ready to read when the TLSCertValidate event is fired by the client component.
This property is read-only and not available at design time.
Please refer to the Certificate type for a complete list of fields.TLSSettings Property (CAdESSigner Component)
Manages TLS layer settings.
Syntax
public TLSSettings TLSSettings { get; }
Public ReadOnly Property TLSSettings As TLSSettings
Remarks
Use this property to tune up the TLS layer parameters.
This property is read-only.
Please refer to the TLSSettings type for a complete list of fields.TrustedCertificates Property (CAdESSigner Component)
A list of trusted certificates for chain validation.
Syntax
public CertificateList TrustedCertificates { get; }
Public Property TrustedCertificates As CertificateList
Remarks
Use this property to supply a list of trusted certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when root CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.
The purpose of this certificate collection is largely the same as that of the Windows Trusted Root Certification Authorities system store.
Use this property with extreme care as it directly affects chain verifiability; a wrong certificate added to the trusted list may result in bad chains being accepted, and forfeited signatures being recognized as genuine. Only add certificates that originate from the parties that you know and trust.
This property is not available at design time.
Please refer to the Certificate type for a complete list of fields.UnsignedAttributes Property (CAdESSigner Component)
Custom unsigned attributes to be included in the electronic signature.
Syntax
public SignatureAttributeList UnsignedAttributes { get; }
Public ReadOnly Property UnsignedAttributes As SignatureAttributeList
Remarks
Signature attributes are used to store auxiliary information in the signature. Values included as unsigned attributes are not covered by the signature and can be changed or removed without affecting the signature.
This property is read-only and not available at design time.
Please refer to the SignatureAttribute type for a complete list of fields.ValidationMoment Property (CAdESSigner Component)
The time point at which signature validity is to be established.
Syntax
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.
AddAttribute Method (CAdESSigner Component)
Adds an attribute to the signature.
Syntax
Remarks
Use this method to add a signed or unsigned attribute to the collection of attributes included in the new signature.
Note that CAdESSigner creates certain mandatory and/or widely used attributes automatically in accordance with requirements for a specific signing profile. For example, attributes such as SigningCertificateV2 or SigningTime are always added. Policy attributes are added if specified via the PolicyID or PolicyURI properties of the signature object.
Use the OID parameter to provide the object identifier of the attribute, in string form. For example, the OID for the SigningCertificateV2 attribute is 1.2.840.113549.1.9.16.2.47. The Value parameter should contain a well-formed, DER-encoded representation of the attribute value, in accordance with its specification.
Archive Method (CAdESSigner Component)
Archives the signature.
Syntax
Remarks
Call this method to produce an archival signature. Archival signature (CAdES-A) is built on top of CAdES-XL by certifying it with an archival timestamp.
Set Baseline to True to produce a baseline CAdES-A.
Close Method (CAdESSigner Component)
Closes an opened container.
Syntax
Remarks
Use this method to close a previously opened container. Set SaveChanges to true to apply any changes made.
Config Method (CAdESSigner Component)
Sets or retrieves a configuration setting.
Syntax
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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, you must call Config("PROPERTY"). The value will be returned as a string.
CreateNew Method (CAdESSigner Component)
Create a new CAdES signature.
Syntax
public void CreateNew();
Public Sub CreateNew()
Remarks
Use this method to create a new CAdES signature. When finished, call Close to complete or discard the operation.
DoAction Method (CAdESSigner Component)
Performs an additional action.
Syntax
Remarks
DoAction is a generic method available in every component. 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;....
ExtractAsyncData Method (CAdESSigner Component)
Extracts user data from the DC signing service response.
Syntax
Remarks
Call this method before finalizing the asynchronous signing process to extract the data passed to the ExternalCrypto.Data property on the pre-signing stage.
The Data parameter can be used to pass some state or document identifier along with the signing request from the pre-signing to the completion async stage.
Open Method (CAdESSigner Component)

Syntax
Remarks
Use this method to re-validate a signature in the opened CAdES signature.
SelectInfo Method (CAdESSigner Component)
Select signature information for a specific entity.
Syntax
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 |

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 |
sitUsedRevInfo | 28672 | Select the whole pack of revocation information used to validate this entity's chain (certificates, CRLs, OCSP responses) |
sitAttributes | 65536 | Select this entity's CMS attributes |
sitReferences | 131072 | Select this entity's XML references |
sitSignedParts | 262144 | Select this entity's signed parts |
Following the call, the relevant pieces of information will be copied to the respective component properties (Certificates, CRLs, OCSPs). Note that you can accumulate information in the properties by making repeated calls to SelectInfo and keeping ClearSelection set to false.
This method is useful if you would like to read/display detailed information about a particular signature or timestamp.
Sign Method (CAdESSigner Component)
Creates a new CAdES signature over the provided data.
Syntax
public void Sign();
Public Sub Sign()
Remarks
Call this method to produce a new signature over the provided data.
SignAsyncBegin Method (CAdESSigner Component)
Initiates the asynchronous signing operation.
Syntax
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 (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 (or InputStream), and call SignAsyncEnd 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 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 component), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.
SignAsyncEnd Method (CAdESSigner Component)
Completes the asynchronous signing operation.
Syntax
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 call to InputFile (or InputStream). The method will embed the signature into the pre-signed document, and save the complete signed document to OutputFile (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) 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 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 component), 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 (CAdESSigner Component)
Signs the document using an external signing facility.
Syntax
public void SignExternal();
Public Sub SignExternal()
Remarks
Use this method to create a CAdES signature using an external signing facility for the cryptographic computations. SignRemote 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 component fires ExternalSign event which allows to pass the hash value for signing.
Timestamp Method (CAdESSigner Component)
Use this method to add timestamp.
Syntax
Remarks
Call this method to add a timestamp to the signature. Use the TimestampServer 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

Public Event OnError As OnErrorHandler Public Delegate Sub OnErrorHandler(sender As Object, e As CAdESSignerErrorEventArgs) Public Class CAdESSignerErrorEventArgs Inherits EventArgs Public ReadOnly Property ErrorCode As Integer Public ReadOnly Property Description As String End Class
Remarks
The event is fired in case of exceptional conditions during message processing.
ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Messages section.
ExternalSign Event (CAdESSigner Component)
Handles remote or external signing initiated by the SignExternal method or other source.
Syntax
public event OnExternalSignHandler OnExternalSign; public delegate void OnExternalSignHandler(object sender, CAdESSignerExternalSignEventArgs e); public class CAdESSignerExternalSignEventArgs : EventArgs { public string OperationId { get; } public string HashAlgorithm { get; } public string Pars { get; } public string Data { get; } public string SignedData { get; set; } }
Public Event OnExternalSign As OnExternalSignHandler Public Delegate Sub OnExternalSignHandler(sender As Object, e As CAdESSignerExternalSignEventArgs) Public Class CAdESSignerExternalSignEventArgs Inherits EventArgs Public ReadOnly Property OperationId As String Public ReadOnly Property HashAlgorithm As String Public ReadOnly Property Pars As String Public ReadOnly Property Data As String Public Property SignedData As String End Class
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 component via the SignedData parameter.
OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.
The component 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:
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();
};
Loaded Event (CAdESSigner Component)

Public Event OnLoaded As OnLoadedHandler Public Delegate Sub OnLoadedHandler(sender As Object, e As CAdESSignerLoadedEventArgs) Public Class CAdESSignerLoadedEventArgs Inherits EventArgs Public Property Cancel As Boolean End Class
Remarks
The handler for this event is a good place to check CAdES signature properties, which may be useful when preparing the signature.
Set Cancel to true to terminate CAdES signature processing on this stage.
Notification Event (CAdESSigner Component)
This event notifies the application about an underlying control flow event.
Syntax
public event OnNotificationHandler OnNotification; public delegate void OnNotificationHandler(object sender, CAdESSignerNotificationEventArgs e); public class CAdESSignerNotificationEventArgs : EventArgs { public string EventID { get; } public string EventParam { get; } }
Public Event OnNotification As OnNotificationHandler Public Delegate Sub OnNotificationHandler(sender As Object, e As CAdESSignerNotificationEventArgs) Public Class CAdESSignerNotificationEventArgs Inherits EventArgs Public ReadOnly Property EventID As String Public ReadOnly Property EventParam As String End Class
Remarks
The component fires this event to let the application know about some event, occurrence, or milestone in the component. 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 component, the exact action it is performing, or the document being processed, one or both may be omitted.
This component can fire this event with the following EventID values:
Loaded | Reports the completion of signature processing by the component. Use the event handler to access signature-related information. The EventParam value passed with this EventID is empty. |
ContentExtracted | Reports the completion of message content extraction by the component if ExtractContent property is enabled. Use the event handler to access message content. The EventParam value passed with this EventID is empty. |
SignaturesLoaded | Notifies the application that the component has finished loading signatures. |
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 component 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 was set to a
virtual:// URI. The EventParam parameter contains the
TSP request (or the plain hash, depending on the value provided to
TimestampServer), 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 (CAdESSigner Component)

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 component 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 SignatureValidationResult and ChainValidationResult properties respectively.
Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.
SignatureValidated Event (CAdESSigner Component)

The CertFound parameter is set to True if the component 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 ValidationResult and ChainValidationResult properties respectively.
Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.
TimestampRequest Event (CAdESSigner Component)
Fires when the component is ready to request a timestamp from an external TSA.
Syntax
public event OnTimestampRequestHandler OnTimestampRequest; public delegate void OnTimestampRequestHandler(object sender, CAdESSignerTimestampRequestEventArgs e); public class CAdESSignerTimestampRequestEventArgs : EventArgs { public string TSA { get; } public string TimestampRequest { get; } public string TimestampResponse { get; set; } public bool SuppressDefault { get; set; } }

SB_CERT_ALGORITHM_EDDSA_SIGNATURE | id-EdDSA-sig |
Scope
int (read-only)
Default: 0
Returns the type of the entity that this signature corresponds to.
A CAdES signature may cover several kinds of entities: the signed data itself (a top-level signature - something you create when you sign documents), a timestamp, or a countersignature.
cssUnknown | 0 | The scope of signature is unknown |
cssData | 1 | The signature is a top-level signature over the data |
cssSignature | 2 | The signature is a countersignature, and is made over another signature |
cssTimestamp | 3 | The signature is made over a timestamp |
SerialNumber
byte[] (read-only)
Default: ""
The serial number of the signing certificate.
SignatureBytes
byte[] (read-only)
Default: ""
Returns the binary representation of the CAdES signature.
SignatureValidationResult
SignatureValidities (read-only)
Default: 0
The outcome of the cryptographic signature validation.
The following signature validity values are supported:
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) |
SubjectKeyID
byte[] (read-only)
Default: ""
Contains the subject key identifier of the signing certificate.
Subject Key Identifier is a (non-critical) X.509 certificate extension which allows the identification of certificates containing a particular public key. In SecureBlackbox, the unique identifier is represented by a SHA-1 hash of the bit string of the subject public key.
SubjectRDN
string (read-only)
Default: ""
Contains the RDN of the owner of the signing certificate.
RDN is a number of OID=Value pairs declared in the certificate and providing the owner's details.
Timestamped
bool (read-only)
Default: False
Use this property to establish whether the signature contains an embedded timestamp.
ValidatedSigningTime
string (read-only)
Default: ""
Contains the certified signing time.
Use this property to obtain the signing time as certified by a timestamp from a trusted timestamping authority. This property is only non-empty if there was a valid timestamp included in the signature.
ClaimedSigningTime returns a non-trusted signing time from the signer's computer.
Both times are in UTC.
ValidationLog
string (read-only)
Default: ""
Contains the signing certificate's chain validation log. This information may be very useful in investigating chain validation failures.
Constructors
public CAdESSignature();
Public CAdESSignature()
Creates a new empty CAdES signature object.
Certificate Type
Encapsulates an individual X.509 certificate.
Remarks
This type keeps and provides access to X.509 certificate details.
Fields
Bytes
byte[] (read-only)
Default: ""
Returns the raw certificate data in DER format.
CA
bool
Default: False
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 field when generating a new certificate to have its Basic Constraints extension generated automatically.
CAKeyID
byte[] (read-only)
Default: ""
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 generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the SubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.
CertType
CertTypes (read-only)
Default: 0
Returns the type of the entity contained in the Certificate object.
A 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 component to load or create new certificate and certificate requests objects.
CRLDistributionPoints
string
Default: ""
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 field 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.
Curve
string
Default: ""
Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

Fingerprint
string (read-only)
Default: ""
Contains the fingerprint (a hash imprint) of this certificate.
While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used.
FriendlyName
string (read-only)
Default: ""
Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.
HashAlgorithm
string
Default: ""
Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use SigAlgorithm to find out the hash algorithm that is part of the certificate signature.

Use the KeyBits, Curve, and PublicKeyBytes fields to get more details about the key the certificate contains.
KeyBits
int (read-only)
Default: 0
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 PublicKeyBytes or PrivateKeyBytes field would typically contain auxiliary values, and therefore be longer.
KeyFingerprint
string (read-only)
Default: ""
Returns a SHA1 fingerprint of the public key contained in the certificate.
Note that the key fingerprint is different from the certificate fingerprint accessible via the Fingerprint field. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.
KeyUsage
int
Default: 0
Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.
This value is a bit mask of the following values:
ckuUnknown | 0x00000 | Unknown key usage |
ckuDigitalSignature | 0x00001 | Digital signature |
ckuNonRepudiation | 0x00002 | Non-repudiation |
ckuKeyEncipherment | 0x00004 | Key encipherment |
ckuDataEncipherment | 0x00008 | Data encipherment |
ckuKeyAgreement | 0x00010 | Key agreement |
ckuKeyCertSign | 0x00020 | Certificate signing |
ckuCRLSign | 0x00040 | Revocation signing |
ckuEncipherOnly | 0x00080 | Encipher only |
ckuDecipherOnly | 0x00100 | Decipher only |
ckuServerAuthentication | 0x00200 | Server authentication |
ckuClientAuthentication | 0x00400 | Client authentication |
ckuCodeSigning | 0x00800 | Code signing |
ckuEmailProtection | 0x01000 | Email protection |
ckuTimeStamping | 0x02000 | Timestamping |
ckuOCSPSigning | 0x04000 | OCSP signing |
ckuSmartCardLogon | 0x08000 | Smartcard logon |
ckuKeyPurposeClientAuth | 0x10000 | Kerberos - client authentication |
ckuKeyPurposeKDC | 0x20000 | Kerberos - KDC |
Set this field before generating the certificate to propagate the key usage flags to the new certificate.
KeyValid
bool (read-only)
Default: False
Returns True if the certificate's key is cryptographically valid, and False otherwise.
OCSPLocations
string
Default: ""
Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.
Set this field before calling the certificate manager's Generate method to propagate it to the new certificate.
The OCSP locations 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.
OCSPNoCheck
bool
Default: False
Accessor to the value of the certificate's ocsp-no-check extension.
Origin
int (read-only)
Default: 0
Returns the location that the certificate was taken or loaded from.
PolicyIDs
string
Default: ""
Contains identifiers (OIDs) of the applicable certificate policies.
The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage.
Set this field when generating a certificate to propagate the policies information to the new certificate.
The policies are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the policy element separator.
PrivateKeyBytes
byte[] (read-only)
Default: ""
Returns the certificate's private key in DER-encoded format. It is normal for this field to be empty if the private key is non-exportable, which, for example, is typical for certificates originating from hardware security devices.
PrivateKeyExists
bool (read-only)
Default: False
Indicates whether the certificate has a usable private key associated with it. If it is set to True, the certificate can be used for private key operations, such as signing or decryption.
This field is independent from PrivateKeyBytes, and can be set to True even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations.
PrivateKeyExtractable
bool (read-only)
Default: False
Indicates whether the private key is extractable (exportable).
PublicKeyBytes
byte[] (read-only)
Default: ""
Contains the certificate's public key in DER format.
This typically would contain an ASN.1-encoded public key value. The exact format depends on the type of the public key contained in the certificate.
Qualified
bool (read-only)
Default: False
Indicates whether the certificate is qualified.
This property is set to True if the certificate is confirmed by a Trusted List to be qualified.
QualifiedStatements
QualifiedStatementsTypes
Default: 0
Returns a simplified qualified status of the certificate.
Qualifiers
string (read-only)
Default: ""
A list of qualifiers.
Contains a comma-separated list of qualifier aliases for the certificate, for example QCP-n-qscd,QCWithSSCD.
SelfSigned
bool (read-only)
Default: False
Indicates whether the certificate is self-signed (root) or signed by an external CA.
SerialNumber
byte[]
Default: ""
Returns the certificate's serial number.
The serial number is a binary string that uniquely identifies a certificate among others issued by the same CA. According to the X.509 standard, the (issuer, serial number) pair should be globally unique to facilitate chain building.
SigAlgorithm
string (read-only)
Default: ""
Indicates the algorithm that was used by the CA to sign this certificate.
A signature algorithm typically combines hash and public key algorithms together, such as sha256WithRSAEncryption or ecdsa-with-SHA256.
Source
PKISources (read-only)
Default: 0
Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response.
Subject
string (read-only)
Default: ""
The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name. This is part of a larger set of credentials available via SubjectRDN.
SubjectAlternativeName
string
Default: ""
Returns or sets the value of the Subject Alternative Name extension of the certificate.
Subject alternative names are used to provide additional names that are impractical to store in the main SubjectRDN field. For example, it is often used to store all the domain names that a TLS certificate is authorized to protect.
The alternative names are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the element separator.
SubjectKeyID
byte[]
Default: ""
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 SubjectKeyID and CAKeyID fields of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.
SubjectRDN
string
Default: ""
A list of Property=Value pairs that uniquely identify the certificate holder (subject).
Depending on the purpose of the certificate and the policies of the CA that issued it, the values included in the subject record may differ drastically and contain business or personal names, web URLs, email addresses, and other data.
Example: /C=US/O=Oranges and Apples, Inc./OU=Accounts Receivable/1.2.3.4.5=Value with unknown OID/CN=Margaret Watkins.
Valid
bool (read-only)
Default: False
Indicates whether or not the signature over the certificate or the request is valid and matches the public key contained in the CA certificate/request.
ValidFrom
string
Default: ""
The time point at which the certificate becomes valid, in UTC.
ValidTo
string
Default: ""
The time point at which the certificate expires, in UTC.

External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.
Fields
AsyncDocumentID
string
Default: ""
Specifies an optional document ID for SignAsyncBegin() and SignAsyncEnd() calls.
Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch. On the completion stage, this value helps the signing component 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 the pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.
CustomParams
string
Default: ""
Custom parameters to be passed to the signing service (uninterpreted).
Data
string
Default: ""
Additional data to be included in the async state and mirrored back by the requestor.
ExternalHashCalculation
bool
Default: False
Specifies whether the message hash is to be calculated at the external endpoint. Please note that this mode is not supported by the DCAuth component.
If set to true, the component will pass a few kilobytes of to-be-signed data from the document to the OnExternalSign event. This only applies when SignExternal() is called.
HashAlgorithm
string
Default: "SHA256"
Specifies the request's signature hash algorithm.

KeyID
string
Default: ""
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 KeySecret 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:
signer.ExternalCrypto.KeyID = "MainSigningKey";
signer.ExternalCrypto.KeySecret = "abcdef0123456789";
KeySecret
string
Default: ""
The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.
Read more about configuring authentication in the KeyID topic.
Method
AsyncSignMethods
Default: 0
Specifies the asynchronous signing method. This is typically defined by the DC server capabilities and setup.
Available options:
asmdPKCS1 | 0 |
asmdPKCS7 | 1 |
Mode
ExternalCryptoModes
Default: 0
Specifies the external cryptography mode.
Available options:
ecmDefault | The default value (0) |
ecmDisabled | Do not use DC or external signing (1) |
ecmGeneric | Generic external signing with the OnExternalSign event (2) |
ecmDCAuth | DCAuth signing (3) |
ecmDCAuthJSON | DCAuth signing in JSON format (4) |
PublicKeyAlgorithm
string
Default: ""
Provide the public key algorithm here if the certificate is not available on the pre-signing stage.
