CryptoCreateHash function

Syntax: result-string = CryptoCreateHash(Algorithm$, Message$)

Discussion: The CryptoCreateHash function produces a binary (non-printable) hash string of the supplied message data using the specified hashing algorithm. The CryptoCreateHash function currently supports 2 hashing algorithms, SHA1 and MD5. The length of the result-string is determined by the algorithm used as follows:

"SHA1" - 160 bits (20 bytes)

"MD5" - 128 bits (16 bytes)


History: This function is available in Comet32 only.

Example:

LENGTH 20 & LOCAL Hash$ ! SHA1 generates a 160 bit (20 byte) result

Hash$ = CryptoCreateHash("SHA1", "Message to hash")
