Hi, i want to use encryption like RSA algorithm in java.
For e.g - during a registeration process in my application, whenever the user inputs a password, i want to encryp that password and pushed that encrypted key into database.
During login process, user will enter his/her username and password, this password will be matched with the decrypted password(encrypted in db) and once validated, it can go through.

Now i have no idea about it. Kindly provide me how to do that using core java ?

Thanks in advance.

The proper approach is not to encrypt passwords, but to hash (or digest) them using an algorithm like SHA-2 (or SHA-256/SHA-384/SHA-512, as it is known in the Java world). That way you can be sure that a password is never exposed. See the SecurityFaq for more information.
