hash - Java calculate hex representation of a SHA-1 digest of a String

Question

I'm storing the user password on the db as a sha1 hash.

Unfortunately I'm getting strange answers.

I'm storing the string as this:

MessageDigest cript = MessageDigest.getInstance("SHA-1");
              cript.reset();
              cript.update(userPass.getBytes("utf8"));
              this.password = new String(cript.digest());

I wanted something like this -->

aff --> "0c05aa56405c447e6678b7f3127febde5c3a9238"

rather than

aff --> ?V@D~fx????:?8

Answer 1

Using apache common codec library:

DigestUtils.sha1Hex("aff")

The result is 0c05aa56405c447e6678b7f3127febde5c3a9238

That's it :)
