Right, thanks. I've got this part, and I am using Key-based AES encryption.
However, I have another question -- not directly related to the subject of the
thread. It's about throwing exception in sub-classes.
Take this case
public setPassword(String plaintextPassword)
{
String hashedPassword =
EncryptionUtilThatThrowsException(plaintextPassword);
super.setPassword(hashedPassword);
}
Here, I can't throw the Exception and I have to handle it here -- but all I
want is to throw the checked exceptions to front-end (calling class) and let
front end to decide what to do with it.
Is there any way to to do this?
Thanks

If you happen to be using the Apache Commons Codec package, you can
use DigestUtils to simplify hashing the password. (You don't actually
want to encrypt the password, just hash it). In your subclass (the
non-underscore one), add something like:
public setPassword(String plaintextPassword)
{
String hashedPassword = DigestUtils.sha256Hex(plaintextPassword);
super.setPassword(hashedPassword);
}
Here is the JavaDoc for DigestUtils:
http://commons.apache.org/codec/api-release/org/apache/commons/codec/digest/DigestUtils.html
Be sure your password field is big enough. For SHA-266, I think you'd
need 64 characters.
