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

Size, in bits, of the key used for encrypting messages. Reserved for future use.

SignatureAlgorithm

CryptoAPI algorithm identifier ( ALG_ID) in use for the signature, if available.

EncryptAlgorithm

CryptoAPI algorithm identifier ( ALG_ID) in use for encrypting messages. Reserved for future use.
