More information: The zip file contains both a VB and a VBScript (ASP) implementation of the SHA-256 one-way encryption algorithm, which is one of the industry standard methods for generating digital signatures. It also contains a form and ASP code that demonstrates the algorithm can be used. The SHA-256 algorithm is one of the industry standard methods for generating digital signatures. It is generically known as a digest, digital signature, one-way encryption, hash or checksum algorithm. A common use for SHA-256 is for password encryption as it is one-way in nature, that does not mean that your passwords are not free from a dictionary attack.
