The Legion of the Bouncy Castle has released version 1.30
of the Bouncy Castle Java Cryptography API, an open source,
clean-room implementation of the Java Cryptography Extension (JCE).
It supports X.509 certificates, PKCS12, S/MIME, CMS, PKCS7, and lots of other juicy acronyms. It also includes its own light-weight crypto API that works in Java 1.0 and later, and does not depend on the JCE.
Version 1.30
adds support for the Canmellia cryptography algorithm
and fixes various bugs.
