The ASiCSigner component creates signature containers.

Syntax

nsoftware.SecureBlackbox.Asicsigner

Remarks

ASiCSigner provides functionality for creating Associated Signature Containers. ASiC containers are used to bind together signed objects and electronic signatures or timestamps.

ASiCSigner supports both ASiC-S (simple) and ASiC-E (extended) signature profiles, as well as the three types of signatures (CAdES, XAdES, and timestamps).

Syntax

public CRLList CRLs { get; }
Public ReadOnly Property CRLs As CRLList

Remarks

Use this property to access the CRLs embedded into the signature by the signer.

This property is read-only and not available at design time.

Extended Property (ASiCSigner Component)

Specifies the type of ASiC signature.

Syntax

public bool Extended { get; set; }
Public Property Extended As Boolean

Default Value

False

Remarks

A simple signature container (ASiC-S) can only be made over a single document, and use one signature format (a CAdES signature, a XAdES signature, or a timestamp)

An extended container (ASiC-E) can cover multiple documents and contain multiple signatures of different types. Set this property to true to create an extended ASiC container.

ExternalCrypto Property (ASiCSigner Component)

Provides access to external signing and DC parameters.

Syntax

public ExternalCrypto ExternalCrypto { get; }
Public ReadOnly Property ExternalCrypto As ExternalCrypto

Remarks

Use this property to tune-up remote cryptography settings. SecureBlackbox supports two independent types of external cryptography: synchronous (based on OnExternalSign event) and asynchronous (based on DC protocol and DCAuth signing component).

This property is read-only.

Files Property (ASiCSigner Component)

Lists all files contained in the container.

Syntax

public ArchivedFileList Files { get; }
Public ReadOnly Property Files As ArchivedFileList

Remarks

Syntax

public bool IgnoreChainValidationErrors { get; set; }
Public Property IgnoreChainValidationErrors As Boolean

Default Value

False

Remarks

If this property is set to True, any errors emerging during certificate chain validation will be ignored. This setting may be handy if the purpose of validation is the creation of an LTV signature, and the validation is performed in an environment that doesn't trust the signer's certificate chain.

InputBytes Property (ASiCSigner Component)

Use this property to pass the input to component in the byte array form.

Syntax

public byte[] InputBytes { get; set; }
Public Property InputBytes As Byte()

Remarks

A path to the ASiC container to process.

Syntax

public string InputFile { get; set; }
Public Property InputFile As String

Default Value

""

Remarks

Syntax

public System.IO.Stream InputStream { get; set; }
Public Property InputStream As System.IO.Stream

Default Value

null

Remarks

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 certificates to be added to this collection is roughly equivalent to that of 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.

KnownCRLs Property (ASiCSigner Component)

Additional CRLs for chain validation.

Syntax

public CRLList KnownCRLs { get; }
Public Property KnownCRLs As CRLList

Remarks

Use this property to supply additional CRLs that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated CRLs are stored separately from the signed message or document.

This property is not available at design time.

KnownOCSPs Property (ASiCSigner Component)

Additional OCSP responses for chain validation.

Syntax

public OCSPResponseList KnownOCSPs { get; }
Public Property KnownOCSPs As OCSPResponseList

Remarks

This property is read-only and not available at design time.

OfflineMode Property (ASiCSigner Component)

Switches the component to the offline mode.

Syntax

public bool OfflineMode { get; set; }
Public Property OfflineMode As Boolean

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 validation information included within the signature or provided via KnownCertificates, KnownCRLs, and other related properties.

OutputBytes Property (ASiCSigner Component)

Use this property to read the output the component object has produced.

Syntax

public byte[] OutputBytes { get; }
Public ReadOnly Property OutputBytes As Byte()

Remarks

The file where the signed data will be saved.

Syntax

public string OutputFile { get; set; }
Public Property OutputFile As String

Default Value

""

Remarks

Provides a path to the file where the component should store the container.

A local path to extract the files to.

Syntax

public string OutputPath { get; set; }
Public Property OutputPath As String

Default Value

""

The stream where the container will be saved.

Syntax

public System.IO.Stream OutputStream { get; set; }
Public Property OutputStream As System.IO.Stream

Default Value

null

Remarks

Use this property to specify the stream to take the resulting signed data.

This property is not available at design time.

Profile Property (ASiCSigner Component)

Specifies a pre-defined profile to apply when creating the signature.

Syntax

public string Profile { get; set; }
Public Property Profile As String

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 (ASiCSigner 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.

RevocationCheck Property (ASiCSigner Component)

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

Syntax

public AsicsignerRevocationChecks RevocationCheck { get; set; }

enum AsicsignerRevocationChecks { crcNone, crcAuto, crcAllCRL, crcAllOCSP, crcAllCRLAndOCSP, crcAnyCRL, crcAnyOCSP, crcAnyCRLOrOCSP, crcAnyOCSPOrCRL }
Public Property RevocationCheck As AsicsignerRevocationChecks

Enum AsicsignerRevocationChecks 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 (CRL) 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)Check all provided CRL endpoints for all chain certificates.
crcAllOCSP (3)Check all provided OCSP endpoints for all chain certificates.
crcAllCRLAndOCSP (4)Check all CRL and OCSP endpoints for all chain certificates.
crcAnyCRL (5)At least one CRL check for every certificate in the chain must succeed.
crcAnyOCSP (6)At least one OCSP check for every certificate in the chain must succeed.
crcAnyCRLOrOCSP (7)At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL (8)At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first.

This setting controls the way the revocation checks are performed. 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 faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

Signatures Property (ASiCSigner Component)

Contains the list of signatures included in the ASiC container.

Syntax

public ASiCSignatureList Signatures { get; }
Public ReadOnly Property Signatures As ASiCSignatureList

Remarks

Use this property to access all signatures in the container.

This property is read-only and not available at design time.

SigningCertificate Property (ASiCSigner Component)

The certificate to be used for signing.

Syntax

public Certificate SigningCertificate { get; set; }
Public Property SigningCertificate As Certificate

Remarks

Use this property to specify the certificate that shall be used for signing the data. Note that this certificate should have a private key associated with it. Use SigningChain to supply the rest of the certificate chain for inclusion into the signature.

This property is not available at design time.

SigningChain Property (ASiCSigner Component)

The signing certificate chain.

Syntax

public CertificateList SigningChain { get; }
Public Property SigningChain As CertificateList

Remarks

This property is not available at design time.

Timestamps Property (ASiCSigner Component)

Contains a collection of timestamps for the processed document.

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.

TimestampServer Property (ASiCSigner Component)

The address of the timestamping server.

Syntax

public string TimestampServer { get; set; }
Public Property TimestampServer As String

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

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.

All the parameters are optional.

TLSClientChain Property (ASiCSigner 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.

This property is not available at design time.

TLSServerChain Property (ASiCSigner 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 read-only and not available at design time.

TLSSettings Property (ASiCSigner 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.

TrustedCertificates Property (ASiCSigner 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 than that of 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.

ValidationMoment Property (ASiCSigner Component)

The time point at which signature validity is to be established.

Syntax

public string ValidationMoment { get; set; }
Public Property ValidationMoment As String

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 signature creation time, or 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.

AddFile Method (ASiCSigner Component)

Use this method to add a file to the archive.

Syntax

public void AddFile();
Public Sub AddFile()

Remarks

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

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

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, 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: 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

Public Function Config(ByVal ConfigurationString As String) As String

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 (ASiCSigner Component)

Performs an additional action.

Syntax

public string DoAction(string actionID, string actionParams);
Public Function DoAction(ByVal ActionID As String, ByVal ActionParams As String) As String

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 of the action is provided in ActionID parameter. ActionParams contains a list of parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

ExtractAsyncData Method (ASiCSigner Component)

Extracts user data from the DC signing service response.

Syntax

public string ExtractAsyncData(string asyncReply);
Public Function ExtractAsyncData(ByVal AsyncReply As String) As String

Remarks

SignAsyncBegin Method (ASiCSigner Component)

Initiates the asynchronous signing operation.

Syntax

public string SignAsyncBegin();
Public Function SignAsyncBegin() As String

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. DC protocol is based on 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 control), which processes it and produces a matching signatures state. The async state produced by the server is then passed to the SignAsyncEnd method.

SignAsyncEnd Method (ASiCSigner Component)

Completes the asynchronous signing operation.

Syntax

public void SignAsyncEnd(string asyncReply);
Public Sub SignAsyncEnd(ByVal AsyncReply As String)

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 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. DC protocol is based on 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 control), which processes it and produces a matching signatures state. The async state produced by the server is then passed to the SignAsyncEnd method.

SignExternal Method (ASiCSigner Component)

Signs the document using an external signing facility.

Syntax

public void SignExternal();
Public Sub SignExternal()

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 component fires ExternalSign event which allows to pass the hash value for signing.

Timestamp Method (ASiCSigner Component)

Use this method to add timestamp.

Syntax

public void Timestamp(int sigIndex, int timestampType);
Public Sub Timestamp(ByVal SigIndex As Integer, ByVal TimestampType As Integer)

Syntax

public void Upgrade(int sigIndex, int toLevel);
Public Sub Upgrade(ByVal SigIndex As Integer, ByVal ToLevel As Integer)

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 level specified by ToLevel. Signatures can normally be upgraded from less sophisticated levels (BES, EPES) to more sophisticated (T, XL, A).

ExternalSign Event (ASiCSigner 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, AsicsignerExternalSignEventArgs e);

public class AsicsignerExternalSignEventArgs : 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 AsicsignerExternalSignEventArgs)

Public Class AsicsignerExternalSignEventArgs 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 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 contain algorithm-dependent parameters.

The component uses base16 (hex) encoding for 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 a .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(); };

FileExtractionStart Event (ASiCSigner Component)

Signifies the start of a file extraction process.

Syntax

public event OnFileExtractionStartHandler OnFileExtractionStart;

public delegate void OnFileExtractionStartHandler(object sender, AsicsignerFileExtractionStartEventArgs e);

public class AsicsignerFileExtractionStartEventArgs : EventArgs {
  public string FileName { get; }
  public long FileSize { get; }
  public string ModDate { get; }
  public bool Extract { get; set; }
  public string DestFile { get; set; }
}
Public Event OnFileExtractionStart As OnFileExtractionStartHandler

Public Delegate Sub OnFileExtractionStartHandler(sender As Object, e As AsicsignerFileExtractionStartEventArgs)

Public Class AsicsignerFileExtractionStartEventArgs Inherits EventArgs
  Public ReadOnly Property FileName As String
  Public ReadOnly Property FileSize As Long
  Public ReadOnly Property ModDate As String
  Public Property Extract As Boolean
  Public Property DestFile As String
End Class

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 component will overwrite it. To prevent overwriting of existing files, subscribe to this event, and change DestFile when needed.

Notification Event (ASiCSigner Component)

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

Syntax

public event OnNotificationHandler OnNotification;

public delegate void OnNotificationHandler(object sender, AsicsignerNotificationEventArgs e);

  public string EventID { get; }
  public string EventParam { get; }
}
Public Event OnNotification As OnNotificationHandler

Public Delegate Sub OnNotificationHandler(sender As Object, e As AsicsignerNotificationEventArgs)

Public Class AsicsignerNotificationEventArgs 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 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:

TimestampRequestA 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.

AddReferenceA 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.

SignatureFound Event (ASiCSigner Component)

Signifies the start of signature validation.

Syntax

public event OnSignatureFoundHandler OnSignatureFound;

public delegate void OnSignatureFoundHandler(object sender, AsicsignerSignatureFoundEventArgs e);

  Public ReadOnly Property SerialNumber As Byte()
  Public ReadOnly Property SubjectKeyID As Byte()
  Public ReadOnly Property CertFound As Boolean
  Public Property ValidateSignature As Boolean
  Public Property ValidateChain As Boolean
End Class

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 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 KnownCertificates property.

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

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

  Public ReadOnly Property Index As Integer
  Public ReadOnly Property IssuerRDN As String
  Public ReadOnly Property SerialNumber As Byte()
  Public ReadOnly Property SubjectKeyID As Byte()
  Public ReadOnly Property CertFound As Boolean
  Public Property ValidateTimestamp As Boolean
  Public Property ValidateChain As Boolean
End Class

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 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 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 SignatureValidationResult and ChainValidationResult properties respectively.

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

TimestampRequest Event (ASiCSigner 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, AsicsignerTimestampRequestEventArgs e);

public class AsicsignerTimestampRequestEventArgs : EventArgs {
  public string TSA { get; }
  public string TimestampRequest { get; }
  public string TimestampResponse { get; set; }
  public bool SuppressDefault { get; set; }
}
Public Event OnTimestampRequest As OnTimestampRequestHandler

Public Class AsicsignerTimestampRequestEventArgs Inherits EventArgs
  Public ReadOnly Property TSA As String
  Public ReadOnly Property TimestampRequest As String
  Public Property TimestampResponse As String
  Public Property SuppressDefault As Boolean
End Class

Remarks

Subscribe to this event to be 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 TimestampServer property. Set SuppressDefault parameter to false 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 Component)

Public Class AsicsignerTLSCertNeededEventArgs Inherits EventArgs
  Public ReadOnly Property Host As String
  Public ReadOnly Property CANames As String
End Class

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 (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 event for the given host and, if the certificate was accepted, succeeded by the TLSEstablished event.

TLSCertValidate Event (ASiCSigner Component)

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

Syntax

public event OnTLSCertValidateHandler OnTLSCertValidate;

public delegate void OnTLSCertValidateHandler(object sender, AsicsignerTLSCertValidateEventArgs e);

public class AsicsignerTLSCertValidateEventArgs : EventArgs {
  public string ServerHost { get; }
  public string ServerIP { get; }
  public bool Accept { get; set; }
}
Public Event OnTLSCertValidate As OnTLSCertValidateHandler

Public Delegate Sub OnTLSCertValidateHandler(sender As Object, e As AsicsignerTLSCertValidateEventArgs)

Public Class AsicsignerTLSCertValidateEventArgs Inherits EventArgs
  Public ReadOnly Property ServerHost As String
  Public ReadOnly Property ServerIP As String
  Public Property Accept As Boolean
End Class

Remarks

This event is fired during a TLS handshake. Use TLSServerChain property to access the certificate chain. In general case, components 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 component, and can be adjusted if needed.

TLSEstablished Event (ASiCSigner Component)

Fires when a TLS handshake with Host successfully completes.

Syntax

public event OnTLSEstablishedHandler OnTLSEstablished;

public delegate void OnTLSEstablishedHandler(object sender, AsicsignerTLSEstablishedEventArgs e);

public class AsicsignerTLSEstablishedEventArgs : EventArgs {
  public string Host { get; }

  Public ReadOnly Property Host As String
  Public ReadOnly Property Version As String
  Public ReadOnly Property Ciphersuite As String
  Public ReadOnly Property ConnectionId As Byte()
  Public Property Abort As Boolean
End Class

Remarks

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

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

TLSHandshake Event (ASiCSigner Component)

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

Syntax

public event OnTLSHandshakeHandler OnTLSHandshake;

public delegate void OnTLSHandshakeHandler(object sender, AsicsignerTLSHandshakeEventArgs e);

public class AsicsignerTLSHandshakeEventArgs : EventArgs {
  public string Host { get; }
  public bool Abort { get; set; }
}
Public Event OnTLSHandshake As OnTLSHandshakeHandler

Public Delegate Sub OnTLSHandshakeHandler(sender As Object, e As AsicsignerTLSHandshakeEventArgs)

Public Class AsicsignerTLSHandshakeEventArgs Inherits EventArgs
  Public ReadOnly Property Host As String
  Public Property Abort As Boolean
End Class

Remarks

The component 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 with TLSEstablished event. If the server chooses to request a client certificate, TLSCertNeeded event will also be fired.

TLSShutdown Event (ASiCSigner Component)

Reports the graceful closure of a TLS connection.

Syntax

public event OnTLSShutdownHandler OnTLSShutdown;

public delegate void OnTLSShutdownHandler(object sender, AsicsignerTLSShutdownEventArgs e);

public class AsicsignerTLSShutdownEventArgs : EventArgs {
  public string Host { get; }
}

CRL Type

Represents a Certificate Revocation List.

Remarks

CRLs store information about revoked certificates, i.e., certificates that have been identified as invalid by their issuing certificate authority (CA) for any number of reasons.

Each CRL object lists certificates from a single CA and identifies them by their serial numbers. A CA may or may not publish a CRL, may publish several CRLs, or may publish the same CRL in multiple locations.

Unlike OCSP responses, CRLs only list certificates that have been revoked. They do not list certificates that are still valid.

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Remarks

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

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 pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

CustomParams
String

Custom parameters to be passed to the signing service (uninterpreted).

Data
String

Additional data to be included in the async state and mirrored back by the requestor

ExternalHashCalculation

KeyID
String

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 extra protection layer for the protocol and diminishes the risk of 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

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

Specifies the asynchronous signing method. This is typically defined by the DC server capabilities and setup.

Available options:

asmdPKCS10
asmdPKCS71

Mode

Available options:

ecmDefaultThe default value (0)
ecmDisabledDo not use DC or external signing (1)
ecmGenericGeneric external signing with OnExternalSign event (2)
ecmDCAuthDCAuth signing (3)
ecmDCAuthJSONDCAuth signing in JSON format (4)

PublicKeyAlgorithm
String

Provide public key algorithm here if the certificate is not available on the pre-signing stage.

Boolean

Whether to force TLS session resumption when the destination address changes.

PreSharedIdentity
String

Defines the identity used when the PSK (Pre-Shared Key) key-exchange mechanism is negotiated.

String

Contains the pre-shared for the PSK (Pre-Shared Key) key-exchange mechanism, encoded with base16.

PreSharedKeyCiphersuite

Defines the ciphersuite used for PSK (Pre-Shared Key) negotiation.

RenegotiationAttackPreventionMode
RenegotiationAttackPreventionModes

Selects renegotiation attack prevention mechanism.

crapmCompatible0TLS 1.0 and 1.1 compatibility mode (renegotiation indication extension is disabled).
crapmStrict1Renegotiation attack prevention is enabled and enforced.
crapmAuto2Automatically choose whether to enable or disable renegotiation attack prevention.

RevocationCheck
RevocationCheckKinds

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)Check all provided CRL endpoints for all chain certificates.
crcAllOCSP (3)Check all provided OCSP endpoints for all chain certificates.
crcAllCRLAndOCSP (4)Check all CRL and OCSP endpoints for all chain certificates.
crcAnyCRL (5)At least one CRL check for every certificate in the chain must succeed.
crcAnyOCSP (6)At least one OCSP check for every certificate in the chain must succeed.
crcAnyCRLOrOCSP (7)At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL (8)At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first.

This setting controls the way the revocation checks are performed. 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 faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

Config Settings (ASiCSigner Component)

The component 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 component, access to these internal properties is provided through the Config method.

ASiCSigner Config Settings

ASiCOptions:   Specifies the ASiC options.

Contains a comma-separated list of values that specifies ASiC options.

Supported values are:

UseP7MExtensionForExtendedCAdESWhen this flag is set, the *.p7m extension is used for extended CAdES signatures inside the container. Otherwise, the *.p7s extension is used.
EncodeIRIWhen 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.

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.

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.

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.

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.

DislikeOpenEndedOCSPs:   Tells the component 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 component 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).

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.

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 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 component should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the component should trust the certificates residing in the Trusted Root Certification Authorities store.

If 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 TrustedCertificates property) are considered trusted.

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 to emulate the verifying environment without actually changing its security settings.

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 or XAdES attribute.

Defines the "noticeNumbers" part of the NoticeReference signature policy qualifier for CAdES-EPES, in the form of comma-separated notice numbers.

PolicyUNOrganization:   The organization part of the NoticeReference qualifier.

Defines the "organization" part of the NoticeReference signature policy qualifier for CAdES-EPES.

ProductionPlace:   The value to store in the ProductionPlace XAdES attribute.

Sets the value of the ProductionPlace XAdES attribute.

PromoteLongOCSPResponses:   Whether long OCSP responses are requested.

Set this property to True to force the component to publish 'long' form of OCSP responses. Otherwise, only BasicOCSPResponse blobs are promoted.

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 event and handle the AddReference event, where you can provide a separate MIME type for every reference.

TempPath:   Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

TimestampResponse:   A base16-encoded timestamp response received from a TSA.

When using virtual:// timestamp endpoints, assign this property in your Notification event handler with the TSP response that you receive from the TSA. Remember to encode the response in hex (base16).

TLSChainValidationDetails:   Contains the advanced details of the TLS server certificate validation.

Check this property in TLSCertValidate event handler to access the TLS certificate validation details.

TLSChainValidationResult:   Contains the result of the TLS server certificate validation.

Check this property in TLSCertValidate event handler to obtain the TLS certificate validation result.

TLSClientAuthRequested:   Indicates whether the TLS server requests client authentication.

Check this property in TLSCertValidate event handler to find out whether the TLS server requests the client to provide the authentication certificate. If this property is set to true, provide your certificate via TLSClientChain property. Note that the component may fire this event more than once during each operation, as more than one TLS-enabled server may need to be contacted.

TLSValidationLog:   Contains the log of the TLS server certificate validation.

Check this property in TLSCertValidate event handler to retrieve the validation log of the TLS server.

TolerateMinorChainIssues:   Whether to tolerate minor chain issues.

This parameter controls whether the chain validator should tolerate minor technical issues when validating the chain. Those are:

  • CA, revocation source, TLS key usage requirements are not mandated
  • Violation of OCSP issuer requirements are ignored
  • AuthorityKeyID extension in CRL and certificate issuing CAs are ignored (helps with incorrectly renewed certificates)
  • Basic constraints and name constraints of CA certificates are ignored
  • Some weaker algorithms are tolerated
UseMicrosoftCTL:   Enables or disables automatic use of Microsoft online certificate trust list.

Enable this property to make the chain validation module automatically look up missing CA certificates in the public Windows Update repository.

UseSystemCertificates:   Enables or disables the use of the system certificates.

Use this property to tell chain validation module automatically look up missing CA certificates in the system certificates. In many cases it is beneficial to switch this property on, as the operating system certificate configuration provides a representative trust framework.

UseUTF8Filenames:   Specifies whether to use UTF-8 filenames.

Set this property to False to use system encoding for filenames inside container.

UseValidationCache:   Enables or disable the use of the product-wide certificate chain validation cache.

Use this property to enable or disable the use of the global chain validation cache. If enabled, the component will consult the product-wide validation cache when validating the signing chains. Also, the outcomes of any new chain validations performed by the component, both interim and final, will be saved in the cache and available for re-use by any future validations. Disable this property to ignore the cache and always perform the validation from the fresh start.

Base Config Settings

CheckKeyIntegrityBeforeUse:   Enables or disable private key integrity check before use.

This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.

You can switch this property off to improve performance if your project only uses known, good private keys.

CookieCaching:   Specifies whether a cookie cache should be used for HTTP(S) transports.

Set this property to enable or disable cookies caching for the component.

Supported values are:

offNo caching (default)
localLocal caching (supported for HTTPClient, RESTClient and SOAPClient only)
globalGlobal caching

Cookies:   Gets or sets local cookies for the component (supported for HTTPClient, RESTClient and SOAPClient only).

Use this property to get cookies from the internal cookie storage of the component and/or restore them back between application sessions.

DefDeriveKeyIterations:   Specifies the default key derivation algorithm iteration count.

This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided.

EnableClientSideSSLFFDHE:   Enables or disables finite field DHE key exchange support in TLS clients.

This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower algorithm if compared to EC DHE; enabling it may result in slower connections.

This setting only applies to sessions negotiated with TLS version 1.3.

GlobalCookies:   Gets or sets global cookies for all the HTTP transports.

Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the components that have its CookieCaching property set to "global".

HttpUserAgent:   Specifies the user agent name to be used by all HTTP clients.

This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other components.

LogDestination:   Specifies the debug log destination.

Contains a comma-separated list of values that specifies where debug log should be dumped.

Supported values are:

fileFile
consoleConsole
systemlogSystem Log (supported for Android only)

allAll details

LogFile:   Specifies the debug log filename.

Use this property to provide a path to the log file.

LogFilters:   Specifies the debug log filters.

Contains a comma-separated list of value pairs ("name:value") that describe filters.

Supported filter names are:

exclude-packageExclude a package specified in the value
exclude-moduleExclude a module specified in the value
exclude-classExclude a class specified in the value
exclude-methodExclude a method specified in the value
include-packageInclude a package specified in the value
include-moduleInclude a module specified in the value
include-classInclude a class specified in the value
include-methodInclude a method specified in the value

LogFlushMode:   Specifies the log flush mode.

Use this property to set the log flush mode. The following values are defined:

noneNo flush (caching only)
immediateImmediate flush (real-time logging)
maxcountFlush cached entries upon reaching LogMaxEventCount entries in the cache.

LogLevel:   Specifies the debug log level.

Use this property to provide the desired debug log level.

Supported values are:

noneNone (by default)
fatalSevere errors that cause premature termination.
errorOther runtime errors or unexpected conditions.
warningUse of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
infoInteresting runtime events (startup/shutdown).
debugDetailed information on flow of through the system.
traceMore detailed information.

LogMaxEventCount:   Specifies the maximum number of events to cache before further action is taken.

Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode.

The default value of this setting is 100.

LogRotationMode:   Specifies the log rotation mode.

Use this property to set the log rotation mode. The following values are defined:

noneNo rotation
deleteolderDelete older entries from the cache upon reaching LogMaxEventCount
keepolderKeep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded)

MaxASN1BufferLength:   Specifies the maximal allowed length for ASN.1 primitive tag data.

This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

MaxASN1TreeDepth:   Specifies the maximal depth for processed ASN.1 trees.

This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

OCSPHashAlgorithm:   Specifies the hash algorithm to be used to identify certificates in OCSP requests.

This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

Tag:   Allows to store any custom data.

Use this config property to store any custom data.

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.

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.
