The BC FIPS Description contains a broad overview of the motivations and design of the BC FIPS Java module.
As of BC Java 1.54 from a JCA/JCE point of view the module is largely a drop in replacement and can be used with the other BC APIs for certificate generation, CMS, TSP, S/MIME, OpenPGP and other protocols. Owing to the requirements of FIPS, particularly in respect to boundary issues the lightweight API is quite different, however the ASN.1 modules and the EC math module is the same.
