Legion of the Bouncy Castle

“Here at the Bouncy Castle, we believe in encryption. That’s something that’s near and dear to our hearts. We believe so strongly in encryption, that we’ve gone to the effort to provide some for everybody. The Bouncy Castle Crypto APIs consist of the following: A lightweight cryptography API in Java; A provider for the JCE and JCA; A clean room implementation of the JCE 1.2.1; A library for reading and writing encoded ASN.1 objects; Generators for Version 1 and Version 3 X.509 certificates and PKCS12 files; Generators/Processors for S/MIME and CMS (PKCS7); Generators/Processors for OCSP (RFC 2560); Generators/Processors for OpenPGP (RFC 2440); A signed jar version suitable for JDK 1.4 and the Sun JCE. The lightweight API works with everything from the J2ME to the JDK 1.4.”
