HMAC MD5 to Match RFC 2022 Test Vectors

Demonstrates using Chilkat in _LANGUAGE_ to computer HMAC MD5 message authentication codes to match the test vectors given by RFC 2202. VBScript

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' The output will be Hex, so set the EncodingMode:
