The Legion of the Bouncy Castle Java Cryptography API provides a lightweight cryptography API in Java, a provider for the JCE and JCA, a clean-room implementation of the JCE 1.2.1, generators for Version 1 and Version 3 X.509 certificates, generators for Version 2 X.509 attribute certificates, PKCS12 support, and APIs for dealing with S/MIME, CMS, OCSP, TSP, CMP, CRMF, EAC, DVCS, OpenPGP, DTLS, and TLS. Versions are provided for the J2ME, and JDK 1.0-1.7.

Changes:
This release adds support for server/client side TLS 1.1 and server/client side DTLS 1.0, the SipHash MAC algorithm, the 4 DRBGs specified in NIST SP 800-90A, OCB mode, and the GMAC algorithm (NIST SP 800-38D). In addition, it is now possible to store OCSP objects in CMS SignedData, parameter and key generation is now fully supported for the keys sizes specified in DSA 2, and support has been added for the SHA-512/t digest varients. A number of bugs and an encoding regression with T61 Strings have also been fixed
