Instead of comparing a string, Is there any inbuilt class or method in java for validation, encryption and recovery of password . Or else is there any usable class library available for such a purposes. Thank you!!

Answer 1

Yes, and no. It is common to use a MessageDigest to accomplish this, by applying a one way cryptographic hash function to the user's password (e.g. one of SHA-256, SHA-384, and SHA-512 [and there are others]) and a SALT to prevent rainbow table based attacks. All of which can certainly be accomplished with native "inbuilt" Java.
