Class AESParameters

All Implemented Interfaces:

public class AESParameters
extends Object
implements AlgorithmParameters
The parameters required for the AES symmetrical encryption scheme. It can be used to encrypt and decrypt data with a single, secret key. Whoever has this key is able to decrypt the encrypted data. Therefore, the key must be stored in a secure way.

AES can be used for example to encrypt data on storage. If you want to encrypt messages, you should use a hybrid scheme (see RSA_KEMParameters or McEliece_KEMParameters), where an asymmetric key is used in addition to encrypt and share the secret key with the receiver of the message.

      public AESParameters​(AESParameters.Keysize keySize, AESParameters.Mode mode, AESParameters.Padding padding)
      Creates a new AESParameters object with the given keySize, mode and padding scheme. AES is an symmetrical encryption scheme.
      keySize - The size of the AES key. It can be 128, 192 or 256 bit.
      mode - The mode used for encryption.
      padding - The padding scheme used for encryption.
