Syntax

public static class DigestAlgorithm

Methods

CalculateDigest(Type, byte[])

Declaration

public static byte[] CalculateDigest(DigestAlgorithm.Type in_digest_algorithm_type, byte[] in_message_buf)

Parameters

Type	Name	Description
DigestAlgorithm.Type	in_digest_algorithm_type
byte[]	in_message_buf

Returns

Type	Description
byte[]

SignDigest(byte[], Type, byte[], string)

Sign the digest of arbitrary data with private key in the provided PKCS #12 key file (.pfx). This function is part of the low-level custom signing API, and works with GenerateESSSigningCertPAdESAttribute, GenerateCMSSignedAttributes, and GenerateCMSSignature.

Declaration

public static byte[] SignDigest(byte[] digest_buf, DigestAlgorithm.Type digest_algorithm_type, byte[] pkcs12_buf, string pkcs12_password)

Parameters

Type	Name	Description
byte[]	digest_buf	The digest to sign
DigestAlgorithm.Type	digest_algorithm_type	The digest algorithm used to generate the digest
byte[]	pkcs12_buf	The buffer containing the PKCS #12 key (as usually stored in .pfx files) to use for signing
string	pkcs12_password	The password to use to parse the PKCS 12 key

Returns

Type	Description
byte[]	the DER-serialized bytes of the signature

SignDigest(byte[], Type, string, string)

Declaration

public static byte[] SignDigest(byte[] digest_buf, DigestAlgorithm.Type digest_algorithm_type, string pkcs12_keyfile_path, string pkcs12_password)

Parameters

Type	Name	Description
byte[]	digest_buf	The digest to sign
DigestAlgorithm.Type	digest_algorithm_type	The digest algorithm used to generate the digest
string	pkcs12_keyfile_path	The path to the PKCS #12 keyfile (usually has a .pfx extension) to use for signing
string	pkcs12_password	The password to use to parse the PKCS #12 keyfile

Returns

Type	Description
byte[]	the DER-serialized bytes of the signature
