The version Claudio posted now adds Cisco support to existing raw-sha256-opencl source file, so only a few functions differs and there are two format structs. While it is technically a separate format, it's not a new source file (and I presume it uses the same OpenCL kernel too). > > Just thinking out loud, I wonder how hard it would be to write a single format (as in using *one* format struct) that reads hex or base64 hashes, and writes pot file entries in the format they came - while still recognizing cracked hashes from the "other" encoding. Maybe it would just get messy. That was easy, using prepare(). I just added (in bleeding) support for native Cisco type 4 hashes (tagged or not) to the existing raw-sha256 format. The .pot entries are compatible with normal, hex-encoded, raw-sha256 hashes. We should do the same to OpenCL and ditch the (semi-)separate format. magnum
