A curated set of links on JCE and JCA — installing unlimited strength jurisdiction policy files, provider setup, and using BouncyCastle for advanced cryptographic operations in Java.
The Java Cryptography Extension (JCE) builds on the Java Cryptography Architecture (JCA) to provide encryption, key generation, and message authentication for Java applications. The resources below cover installing the unlimited strength policy files required for stronger key sizes, working with the BouncyCastle provider, and understanding how JCA and JCE fit together.
