Members
sSignatureAlgorithmName
Pointer to a null-terminated string that contains the name, if available, of the algorithm used for generating signatures, such as “MD5”, “SHA-2”, and so on.
sEncryptAlgorithmName
Pointer to a null-terminated string that contains the name, if available, of the algorithm used for encrypting messages. Reserved for future use.
KeySize
Specifies the size, in bits, of the key used for encrypting messages. Reserved for future use.
SignatureAlgorithm
Specifies the CryptoAPI algorithm identifier (ALG_ID, documented in the Platform SDK) in use for the signature, if available.
EncryptAlgorithm
Specifies the CryptoAPI algorithm identifier (ALG_ID) in use for encrypting messages. Reserved for future use.
