ediSecurityCertificate. GetDigitalSignature

Returns the string representation of the digital signature of the file.

Syntax:

• <lretval> = object.GetDigitalSignature(<sFileName>, <lEncodingFilter>, <sSignAlgorithm>, <lSignatureFormatType>)

Parameters:

• sFileName – Full path name of file to sign.
• lEncodingFilter – Encoding mechanism to translate the binary contents of the resulting digital signature to a string.  Supported encoding mechanisms are listed under Encoding Mechanism Type Constants.
• sSignAlgorithm – Signature algorithm used to sign the file.
• lSignatureFormatType – Signature format of resulting digital signature.  The supported signature formats are listed in Signature Format Type Constants.

Remarks:

For the certificate to sign a file, the certificate uses the private key that it has been associated to.  The association to the private key is required because the certificate does not hold the private key -- only the public key.  To associate a certificate to a private key in the Cryptographic Service Provider key container, invoke the methods UpdateCSP or DetermineCSP.
