Title Body

I use jdbcRealm for security in my glassfish v3.0.1 b22. It is set up so that it use the USER table inside my database for authentication by following this blog: http://blogs.oracle.com/foo/entry/mort_learns_jdbc_realm_authentication . I got it working fine, if I leave the digest algorithm as plain text. However when i try to use SHA-256 for digest algorithm, it stop working. What I did is specify in Glassfish - Security - Realm - jdbcRealm - digest that I want SHA-256 (I just type SHA-256 inside digest field). Then I wrote a simple Java program to convert password text into SHA-256 hash. I then paste that hash inside my password field in the database. By the way, password field is type varchar(30). I cant log in anymore. One thing I notice that my simple Java program generated different hash every time for the same text field. Below are my simple java program: MessageDigest md = MessageDigest.getInstance("SHA-256"); String text = "admin"; md.update(text.getBytes("UTF-8")); byte[] digest = md.digest(); System.out.println(digest.toString());
