(PowerBuilder) HMAC MD5 to Match RFC 2022 Test Vectors

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

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

// Use "Chilkat_9_5_0.Crypt2" for versions of Chilkat < 10.0.0

    destroy loo_Crypt

// The output will be Hex, so set the EncodingMode:
loo_Crypt.EncodingMode = "hex"

// Set the hash algorithm:
// Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
loo_Crypt.HashAlgorithm = "md5"

// Set the HMAC key:
