vAppendSHA256AlgorithmIdentifierSequence

Appends digest algorithm sequence to SHA-256 hash for RSA signatures.

CK_RV vAppendSHA256AlgorithmIdentifierSequence( const uint8_t * puc32ByteHashedMessage,
                                                uint8_t * puc51ByteHashOidBuffer );

This function pre-appends the digest algorithm identifier to the SHA-256 hash of a message.

DigestInfo :: = SEQUENCE{ digestAlgorithm DigestAlgorithmIdentifier, digest Digest }

Parameters

[in]	puc32ByteHashedMessage	A 32-byte buffer containing the SHA-256 hash of the data to be signed.
[out]	puc51ByteHashOidBuffer	A 51-byte output buffer containing the DigestInfo structure. This memory must be allocated by the caller.

Returns

CKR_OK if successful, CKR_ARGUMENTS_BAD if NULL pointer passed in.
