The Legion of the Bouncy Castle has released version 1.37
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, TEA, XTEA, SHA224, SEED, Salsa20, 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.
According to the announcement:
1.37 is a mixture of enhancements and defect fixes. On the enhancements side we have new block ciphers (CCM, EAX, Noekeon), new stream ciphers (HC-128/256, ISAAC), improvements to PGP signature processing and compatibility improvements in CMS.
