MD5 Encoding

August 2, 2006 in JBoss

By using the MD5 Encoding, we can create encryted password using message digest technology. To do this, we can make use of utility provided by JBoss. See the following:

If you need to generate passwords in code, the org.jboss.security.Util class provides a static helper method that will hash a password using a given encoding.

String hashedPassword = Util.createPasswordHash("MD5",
                                                Util.BASE64_ENCODING,
                                                null,
                                                null,
                                                "password");

OpenSSL provides an alternative way to quickly generate hashed passwords.

echo -n password | openssl dgst -md5 -binary | openssl base64

In both cases, the text password should hash to “X03MO1qnZdYdgyfeuILPmQ==”. This is the value that would need to be stored in the user store.

The about org.jboss.security.Util class can be found in the jbossx.jar shipped with JBoss Application Server.
