The Bouncy Castle Crypto Package For C Sharp

The Bouncy Castle Crypto package is a C# implementation of cryptographic algorithms and protocols, it was developed by the Legion of the Bouncy Castle, a registered Australian Charity, with a little help! The Legion, and the latest goings on with this package, can be found at https://www.bouncycastle.org. In addition to providing basic cryptography algorithms, the package also provides support for CMS, TSP, X.509 certificate generation and a variety of other standards such as OpenPGP.

The Legion also gratefully acknowledges the contributions made to this package by others (see here for the current list). If you would like to contribute to our efforts please feel free to get in touch with us or visit our donations page, sponsor some specific work, or purchase a support contract through Crypto Workshop.

Except where otherwise stated, this software is distributed under a license based on the MIT X Consortium license. To view the license, see here. The OpenPGP library also includes a modified BZIP2 library which is licensed under the Apache Software License, Version 2.0.
