' ' ASP VBScript code for generating a SHA256 'digest' or 'signature' of a string. The ' MD5 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 SHA256 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. ' ' If you are using the routine for passwords, you can make it a little more secure ' by concatenating some known random characters to the password before you generate ' the signature and on subsequent tests, so even if a hacker knows you are using ' SHA-256 for your passwords, the random characters will make it harder to dictionary ' attack. ' ' NOTE: Due to the way in which the string is processed the routine assumes a ' single byte character set. VB passes unicode (2-byte) character strings, the ' ConvertToWordArray function uses on the first byte for each character. This ' has been done this way for ease of use, to make the routine truely portable ' you could accept a byte array instead, it would then be up to the calling ' routine to make sure that the byte array is generated from their string in ' a manner consistent with the string type.
