local chilkat = require("chilkat")

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

local crypt = chilkat.Crypt2.new()

-- The output will be Hex, so set the EncodingMode:
crypt.encoding_mode = "hex"

-- Set the hash algorithm:
-- Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
crypt.hash_algorithm = "md5"
crypt.mac_algorithm = "hmac"

-- Set the HMAC key:
crypt:set_mac_key_encoded("0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b", "hex")
local mac = crypt:mac_string_enc("Hi There")
