require 'chilkat'

crypt = Chilkat::CkCrypt2.new()

#  Any string argument automatically begins the 30-day trial.
success = crypt.UnlockComponent("Anything for 30-day trial.")
if (success != true)
    print crypt.lastErrorText() + "\n";
    exit
end

#  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("sha-1")

#  Set the HMAC key:
crypt.SetHmacKeyEncoded("0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b","hex")
mac = crypt.hmacStringENC("Hi There")
print mac + "\n";

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