    • Constructor Detail

      • AES256Options

        AES256Options​(char[] password)
        Parameters:
        password - password used for encryption

      • AES256Options

        AES256Options​(char[] password,
              byte[] salt,
              byte[] iv,
              int numCyclesPower)
        Parameters:
        password - password used for encryption
        salt - for password hash salting (enforce password security)
        iv - Initialization Vector (IV) used by cipher algorithm
        numCyclesPower - another password security enforcer parameter that controls the cycles of password hashing. More the this number is high, more security you'll have but also high CPU usage
