MD5 hash generator

What is MD5 algorithm?

Message Digest Algorithm 5 (MD5) is a cryptographic hash algorithm that can be used to create a 128-bit string value from an arbitrary length string. ... MD5 is most commonly used to verify the integrity of files. However, it is also used in other security protocols and applications such as SSH, SSL, and IPSec.

Although MD5 was initially designed to be used as a cryptographic hash function, it has been found to suffer from extensive vulnerabilities. It can still be used as a checksum to verify data integrity, but only against unintentional corruption. It remains suitable for other non-cryptographic purposes, for example for determining the partition for a particular key in a partitioned database

MD5 in programming languages

Will the MD5 cryptographic hash function output be same in all programming languages?
Yes, correct implementation of md5 will produce the same result, otherwise md5 would not be useful as a checksum. The difference may come up with encoding and byte order. You must be sure that text is encoded to exactly the same sequence of bytes.

Is it possible to decode the MD5?
No, that's not possible.

MD5 in C#

C# how to convert string to MD5 hash?
MD5 Class in Microsoft documentation

public string CreateMD5HashWithCShap(string input) {
  // Step 1, calculate MD5 hash from input
  MD5 md5 = System.Security.Cryptography.MD5.Create();
  byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes(input);
  byte[] hashBytes = md5.ComputeHash(inputBytes);

  // Step 2, convert byte array to hex string
  StringBuilder sb = new StringBuilder();
  for (int i = 0; i < hashBytes.Length; i++) {
    sb.Append(hashBytes[i].ToString("X2"));
  }
  return sb.ToString();
}

public class MD5 {
  public static String getMd5(String input) {
    try {
      // Static getInstance method is called with hashing MD5
      MessageDigest md = MessageDigest.getInstance("MD5");

      // digest() method is called to calculate message digest
      //  of an input digest() return array of byte
      byte[] messageDigest = md.digest(input.getBytes());

      // Convert byte array into signum representation
      BigInteger no = new BigInteger(1, messageDigest);

      // Convert message digest into hex value
      String hashString = no.toString(16);
      while (hashString.length() < 32) {
        hashString = "0" + hashString;
      }
      return hashString;
    }
    catch(NoSuchAlgorithmException e) {
      // For specifying wrong message digest algorithms
      throw new RuntimeException(e);
    }
  }
