(Ruby) HMAC MD5 to Match RFC 2022 Test Vectors

Demonstrates using Chilkat in Ruby 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.

crypt = Chilkat::CkCrypt2.new()

# The output will be Hex, so set the EncodingMode:
crypt.put_EncodingMode("hex")

# Set the hash algorithm:
# Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
crypt.put_HashAlgorithm("md5")
crypt.put_MacAlgorithm("hmac")

# Set the HMAC key:
crypt.SetMacKeyEncoded("0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b","hex")
mac = crypt.macStringENC("Hi There")
print mac + "\n";

crypt.SetMacKeyEncoded("Jefe","ansi")
mac = crypt.macStringENC("what do ya want for nothing?")
print mac + "\n";
