HMAC SHA-1 to Match RFC 2022 Test Vectors

Demonstrates using Chilkat in _LANGUAGE_ to computer HMAC SHA-1 message authentication codes to match the test vectors given by RFC 2202. PowerBuilder

// 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:

// Set the hash algorithm:
// Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval

// Set the HMAC key:
