The functions described in this section are used by application developers to compute hashes (also known as message digests), and are also used to create and verify digital signatures. The following table briefly describes each function.
Function | Description |
---|---|
CryptCreateHash | Create an empty hash object. |
CryptDestroyHash | Destroy a hash object. |
CryptGetHashParam | Retrieve a hash object parameter. |
CryptHashData | Hash a block of data, adding it to the specified hash object. |
CryptHashSessionKey | Hash a session key, adding it to the specified hash object. |
CryptSetHashParam | Set a hash object parameter. |
CryptSignHash | Sign the specified hash object. |
CryptVerifySignature | Verify a digital signature, given a handle to the hash object. |
