Support for bcrypt(md5($p)) on FPGA or --single && --stdout?

Not a bug but a feature request.

To audit bcrypt hashes, I use an old ZTEX clone board. Works perfect and fast compared to my 'conventional' GPU-rig (big thanks for supporting FPGAs!).

I want to audit a number of bcrypt(md5($p)) hashes now, at full ZTEX speed. The quick workaround is using --format=bcrypt-ztex --wordlist=md5_of_wordlist. However the powerful --single mode doest not work and the combination of --single and --stdout to do the same trick is not working ('Invalid options combination or duplicate option').

I understand that adding new FPGA algorithms is very complex. However, I thought that it might be doable to add format bcryptmd5-ztex where the onchanged bcrypt bitstream is used and MD5 pre and post processing is done by the CPU (since the CPU is by far fast enough to MD5 on the fly to keep the ZTEX busy).

Or more simple: is it possible to add support for --single in combination with --stdout so I can do the MD5 processing myself?

Or perhaps smarter tricks I didn't think of? :) Thank you.

Review the existing bcrypt-ztex format and the command-line handling for --single and --stdout. Compare the requested bcrypt(md5($p)) workflow with the md5_of_wordlist workaround, then define a testable outcome for FPGA auditing or the option combination.
