I just did some Google web searches (I am not familiar with development under Windows, not even with Cygwin, although I maintain support for that in JtR), and there appear to be three ways to do it: 1. If the DLL is not stripped, you may convert it to a .a static library and link against that: http://www.cygwin.com/cygwin-ug-net/dll.html http://wiki.tcl.tk/2435 2. If you have a .lib file corresponding to the DLL, you may link to it dynamically. 3. For arbitrary DLLs, you may load/use them via Win32 API calls, which are in turn available via existing Cygwin DLLs: http://gcc.gnu.org/ml/gcc-help/2002-12/msg00088.html Please give these a try. If unsuccessful for another day, please join the john-dev list and bring your question up in there. It is on topic for john-dev, and there are people on that list more familiar with development on Windows than I am. > - Priorities > - GSoC's Midterm evaluations > - Eksblowfish loop and JtR integration > - one core > - multiple cores Sounds fine. Obviously, we'll need to return to our main project soon, but being able to interface to multiple crypto cores is desirable anyway. Thanks, Alexander
