Package javacard.security Description

Provides classes and interfaces that contain publicly-available functionality for implementing a security and cryptography framework on the Java Card platform. Classes which contain security and cryptography functionality which may be subject to export controls are contained in the optional package javacardx.crypto.

Classes in the javacard.security package provide the definitions of algorithms that perform these security and cryptography functions:

• Implementations for a variety of different cryptographic keys
• Factory for building keys (see KeyBuilder)
• Data hashing (see MessageDigest)
• Random data generation (see RandomData)
• Signing using cryptographic keys (see Signature)
• Session key exchanges (see KeyAgreement)
