Generate a hash using java with few lines of code (complete)

In my previous post, I shared a method for converting a text using hash algorithms such as MD5 and SHA-1 .. well, now, I share a utility in java that allows conversions using various algorithms.

Generate a hash using java with few lines of code

Below I share an snippet of code in Java language, which can generate with just 3 lines of code, a text using cryptographic hash functions SHA1 (Secure Hash Algorithm, Secure Hash Algorithm version 2)

public static String generate (String input) throws Exception {
  MessageDigest md = MessageDigest.getInstance ("SHA1");
  byte [] = md.digest digested (input.getBytes ());
  return new BigInteger (1, digested) .toString (16);
}


To use MD5, just change the string "SHA1" with "MD5"
