The Legion of the Bouncy Castle has released version 1.42
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, 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:
This release adds Grain v1, and Grain128, as well as basic support for AuthenticatedData to the CMS API. Further work has been done to improve the BC APIs working with Provider objects rather than provider names and JDK 1.5 and 1.6 jars are now pack200 friendly.
