Implementations

Americans have a silly law that code written in the USA that does strong encryption cannot be exported outside the USA and Canada, even though the algorithms are published. This has had the effect of stimulating European and Australians to provide such software which is immune to the restriction, taking business away from American companies. In particular, BouncyCastle.org is located in Australia. You can use Sun’s weak or strong JCE, but if you use the strong JCE, you can’t export your product. The solution is to plug-replace Sun’s JCE with one written outside the USA.

The ABA (Australian Business Access) provided a clean room implementation of JCE 1.2, including a cryptographic service provider, for international use. ABA seems to have disappeared.

BouncyCastle, another Australian group, has a free cleanroom implementation of JCE 1.2.1.

An Austrian university foundation with the unlikely name of SIC IAIK TUG (which stands for Stiftung Secure Information and Communication Technologies Institute for Applied Information Processing and Communications) has produced a large commercial JCE implementation that includes SSL and AES.
