There are some in the tests[] arrays in:

http://cvsweb.openwall.com/cgi/cvsweb.cgi/Owl/packages/john/john/src/BF_fmt.c?rev=HEAD
http://cvsweb.openwall.com/cgi/cvsweb.cgi/Owl/packages/glibc/crypt_blowfish/wrapper.c?rev=HEAD

and also on these wiki pages:

http://openwall.info/wiki/john/sample-hashes
http://openwall.info/wiki/john/Generating-test-hashes

You need those starting with "$2a$".

Sounds good.  Please be sure to show some code soon!

I suggest that you create this wiki page:

http://openwall.info/wiki/john/FPGA

You may start to use it similarly to this one:

http://openwall.info/wiki/john/GUI

(but with focus on source code and performance rather than on screenshots,
although those are desirable to provide as well if relevant).

Thanks,

Alexander
