AESGCMTools

public AESGCMTools(String password,
                   String salt,
                   String nonce,
                   int iterationCount,
                   int keyLength)
            throws NoSuchAlgorithmException,
                   InvalidKeySpecException

Parameters:

password -

salt - A salt is a unique, randomly generated string that is added to each password as part of the hashing process.

nonce - A nonce or an initialization vector is a random value chosen at encryption time and meant to be used only once.

iterationCount -

keyLength -

Throws:

NoSuchAlgorithmException

InvalidKeySpecException
