We had a discussion on this very list with Piyush Mittal regarding
changing more of the JtR "formats" to use the bitslice DES
implementation. (Right now, many formats use non-bitslice DES code from
OpenSSL instead - I guess primarily because the contributors of those
did not figure out how to use the bitslice implementation.) If you're
interested, please locate and read my replies to Piyush Mittal's many
postings on the subject. Something like:

although I think there were more postings on that topic.
Additionally, we have a bitslice SHA-256 and SHA-512 task mentioned here:
