The AEADCipher class is the abstract base class for Authenticated Encryption with Associated Data (AEAD) ciphers.
Extension package that contains functionality, which may be subject to export controls, for implementing a security and cryptography framework on the Java Card platform. The platform must support this optional package only if cryptographic encryption and decryption functionality is included in the implementation. Classes that contain security and cryptography functionality that are not subject to export control restrictions are contained in the package javacard.security.
The javacardx.crypto package contains the Cipher class and the KeyEncryption interface. Cipher provides methods for encrypting and decrypting messages. KeyEncryption provides functionality that allows keys to be updated in a secure end-to-end fashion.
