Hi All,

I am encoding password text using org.acegisecurity.providers.encoding.Md5PasswordEncoder and org.acegisecurity.providers.dao.SaltSource
using following code

PasswordEncoder encoder = new Md5PasswordEncoder();
encoder.encodePassword(this.password.trim(), this.getSaltSource());


Now i need to decode the same. i tried a lot but didnot succeed.

Any suggestion how to do it.

TIA

I'm not familiar with that particular class, but MD5 is not an encoding - it is cryptographic hash which cannot be reversed. If you want to compare it to a newly entered password, then you need to run that password through the Md5PasswordEncoder as well, and compare the results.
