The JCA and the JCE provide a set of classes and interfaces (included in packages such as curity, javax.crypto, and ) used by the programmer to communicate with the provider of the actual cryptographic algorithms. The Java Cryptography Architecture has been defined as an independent layer. Because now it is included in the JDK, the two terms are used together to describe the same architecture. There are two terms, JCA and JCE, because prior to JDK 1.4 the JCE was an unbundled product. The Bouncy Castle API can be used in J2SE applications in two ways:Īs a Cryptographic Service Provider (CSP) for the Java Cryptography Architecture (JCA) Įach approach has its own advantages that are detailed in the next sections. You must use a cryptographic API which provides the necessary classes and methods. Generating message authentication codes for messages Generating hash values to check the integrity of the message or file Įncryption/decryption using symmetric key algorithms Įncryption/decryption using public certificates in a public key infrastructure

If you want to develop Java applications based on the JSE framework that provide cryptographic services as: In this post we will see how to use Bouncy Castle Cryptographic API either as a JCA provider or as a lightweight API to develop Java J2SE projects in NetBeans 7 (works also on older versions) or Eclipse IDE. The API can be downloaded from the Bouncy Castle latest releases page. The API provides cryptographic functions for Java JDK 1.1 to 1.6 applications and for J2ME (mobile applications) MIDlets. The Bouncy Castle Crypto API for Java provides a lightweight cryptography API that works with everything from the J2ME to the JDK 1.6 platform and also a provider for the Java Cryptography Extension JCE (provides an implementation for JCE 1.2.1) and the Java Cryptography Architecture, JCA.
