How to create hashes (message digests) for strings. Lua

local chilkat = require("chilkat")

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

local crypt = chilkat.Crypt2.new()

local s = "The quick brown fox jumps over the lazy dog"

crypt.hash_algorithm = "sha1"
crypt.encoding_mode = "hex"

-- Other possible EncodingMode settings are:
-- "quoted-printable", "base64","url", and many more..

local hash = crypt:hash_string_enc(s)
print("SHA1: " .. hash)

-- Hash using MD2
crypt.hash_algorithm = "md2"
hash = crypt:hash_string_enc(s)
print("MD2: " .. hash)

-- Hash using MD5
crypt.hash_algorithm = "md5"
hash = crypt:hash_string_enc(s)
print("MD5: " .. hash)

-- Note: SHA-2 is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512)

-- Hash using SHA-256
crypt.hash_algorithm = "sha256"
hash = crypt:hash_string_enc(s)
print("SHA256: " .. hash)

-- Hash using SHA-384
crypt.hash_algorithm = "sha384"
hash = crypt:hash_string_enc(s)
print("SHA384: " .. hash)

-- Hash using SHA-512
crypt.hash_algorithm = "sha512"
hash = crypt:hash_string_enc(s)
print("SHA512: " .. hash)

-- Hash using HAVAL
-- There are two additional properties relevant to HAVAL:
-- HavalRounds, and KeyLength.
-- HavalRounds can have values of 3, 4, or 5.
-- KeyLength can have values of 128, 160, 192, 224, or 256
crypt.hash_algorithm = "haval"
crypt.haval_rounds = 5
crypt.key_length = 256
hash = crypt:hash_string_enc(s)
print("Haval: " .. hash)
