Hi, i have this password, "d8578edf8458ce06fbc5bb76a58c5ca4" what do you think the hashing mechanism? I have use this code to compare, but the differences are too much. Share me your view. MessageDigest digest = java.security.MessageDigest.getInstance("MD5"); digest.update("qwerty".getBytes()); byte[] hash = digest.digest(); System.out.println(Base64Encoder.encode(hash)); and the base64 is from org.jboss.security.Base64Encoder and the output is 2FeO34RYzgb7xbt2pYxcpA== View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4138393#...
