Java has methods to compute digests over data: see the class java.security.MessageDigest. I want to store the pasword in a mysql database table in encrypted form. Again i need to decrypt whenever i need, for example during password verification I want some encryption and decryption program ...
Now we have a mechanism to generate a key pair and save those keys for the future, we can consider how to actually perform RSA encryption/decryption in more detail, reading in the key files we generated. Other encryption and RSA-related topics...
