Java cryptography architecture
How to study this subject
The Java platform strongly emphasizes
security, including language safety, cryptography, public key
infrastructure, authentication, secure communication, and access
control.
The Java cryptography architecture (JCA) is a major piece of the platform, and contains a "provider" architecture and a set of APIs for digital signatures, message digests (hashs), certificates and certificate validation, encryption (symmetric/asymmetric block/stream ciphers), key generation and management, and secure random number generation, to name a few. These APIs allow developers to easily integrate security into their application code. The architecture was designed around the following principles:
Implementation independence
Applications do not need to implement security algorithms. Rather, they can request security services from the Java platform. Security services are implemented in providers (see below), which are plugged into the Java platform via a standard interface. An application may rely on multiple independent providers for security functionality.
Implementation interoperability
Providers are interoperable across applications. Specifically, an application is not bound to a specific provider, and a provider is not bound to a specific application.
Algorithm extensibility
The Java platform includes a number of built-in providers that implement a basic set of security services that are widely used today. However, some applications may rely on emerging standards not yet implemented, or on proprietary services. The Java platform supports the installation of custom providers that implement such services.
