The Bouncy Castle Java APIs for ASN.1 extension and utility APIs used to support bcpkix and bctls with the BC FIPS provider. The APIs may also be used with other providers although if being used in a FIPS context it is the responsibility of the user to ensure that any other providers used are FIPS certified and used appropriately.

There is a newer version: 2.0.3
