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.

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 (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;....

Verify Method (MessageVerifier Component)

Verifies digitally signed data.

Syntax

• C#
• VB.NET

public void Verify();

Public Sub Verify()

Remarks

PKCS#7 and its successor, CMS, support two types of signatures: (1) enveloping signatures, where the signed data and its signature are combined in the same message, and (2) detached signatures, where the signature is stored as a separate entity. This method verifies enveloped signatures and extracts data contained in them. Use VerifyDetached to verify detached signatures.

This method expects the enveloping signature to be provided via InputFile or InputStream properties.

Note that this method only checks the integrity of the signature, i.e., that it is signed with the claimed certificate and has not been altered. It does not validate the signing certificate chain. To validate the certificate chain, either use CertificateValidator component together with MessageVerifier, or consider using CAdESVerifier component instead.

VerifyDetached Method (MessageVerifier Component)

Verifies a detached signature.

Syntax

• C#
• VB.NET

public void VerifyDetached();

Public Sub VerifyDetached()

Remarks

Use this method to verify detached signatures. Pass the signature via InputFile (or InputStream) property, and the original data via DataFile (DataStream).

Error Event (MessageVerifier Component)

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

Public Class MessageverifierNotificationEventArgs Inherits EventArgs
  Public ReadOnly Property EventID As String

The IssuerRDN, SerialNumber, and SubjectKeyID parameters to identify the recipient's certificate. CertFound indicates if the specified certificate has been located in Certificates collection. If it wasn't, you might want to look up the certificate manually, and add it to the collection inside the event handler.

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 (MessageVerifier 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.
