Welcome
Welcome to the home of the Legion of the Bouncy Castle. A fun place to stay, if you've got some time to kill.

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, and we've now been doing it for over 10 years!
The Bouncy Castle Crypto APIs consist of the following:
A lightweight cryptography API for Java and C#.
A provider for the Java Cryptography Extension and the Java Cryptography Architecture.
A clean room implementation of the JCE 1.2.1.
A library for reading and writing encoded ASN.1 objects.
A light weight client-side TLS API.
Generators for Version 1 and Version 3 X.509 certificates, Version 2 CRLs, and PKCS12 files.
Generators for Version 2 X.509 attribute certificates.
Generators/Processors for S/MIME and CMS (PKCS7/RFC 3852).
Generators/Processors for OCSP (RFC 2560).
Generators/Processors for TSP (RFC 3161).
Generators/Processors for OpenPGP (RFC 2440).
A signed jar version suitable for JDK 1.4-1.6 and the Sun JCE.
The lightweight API works with everything from the J2ME to the JDK 1.6 and there is also an API in C# providing equivalent functionality for most of the above.
For further details have a look in either our Java project pages or our C# project pages where you can find downloads, mailing lists, and other resources.
