Java equivalent to MySql and PHP SHA1

The following code snippet demonstrates Java's equivalent to PHP and MySql's SHA1 function: import java.math.BigInteger; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; public class SHA1Test { public static void main(String[] args){ String hashStr = null; String password = "password"; try { MessageDigest md = MessageDigest.getInstance("SHA-1"); md.update(password.getBytes()); BigInteger hash = new BigInteger(1, md.digest()); hashStr = hash.toString(16); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } System.out.println(hashStr); //outputs: 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8 } } mysql> select sha1('password'); +------------------------------------------+ | sha1('password')                         | +------------------------------------------+ | 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8 | +-------------------------
