Step by Step solution about How to resolve the algorithm MD5 step by step in the Haskell programming language

The first code snippet is a Haskell program that computes the MD5 hash of a given string. The md5sum function from the Data.Digest.OpenSSL.MD5 module is used to compute the hash, and the pack function from the Data.ByteString module is used to convert the string to a byte string. The map function is used to convert each character in the string to its ASCII code, and the fromIntegral function is used to convert the ASCII code to an integer.

The second code snippet is also a Haskell program that computes the MD5 hash of a given string. The hash function from the Crypto.Hash module is used to compute the hash, and the pack function from the Data.ByteString.Char8 module is used to convert the string to a byte string. The unwords function from the System.Environment module is used to concatenate the arguments passed to the program into a single string.

Both programs print the MD5 hash of the given string to the standard output.

import Data.Digest.OpenSSL.MD5 (md5sum)
import Data.ByteString (pack)
import Data.Char (ord)

main = do
  let message = "The quick brown fox jumped over the lazy dog's back"
      digest  = (md5sum . pack . map (fromIntegral . ord)) message
  putStrLn digest


#!/usr/bin/env runhaskell

import Data.ByteString.Char8 (pack)
import System.Environment (getArgs)
import Crypto.Hash

main :: IO ()
main = print . md5 . pack . unwords =<< getArgs
         where md5 x = hash x :: Digest MD5
