DONE Raw: 36755 c/s real, 36530 c/s virtual I will get this into jumbo. I wrote SKEY_jtr_plug.c and put all the skey code into there. That file is only 136 lines long, including handling all 4 types, and with comments ;) The SKEY was very trivial code. My code is FAR from optimal, but it works :) It took about an hour or 2, once I got the algorithm trimmed down, and a MD5 example done and working. Then hooking it into what SKEY_fmt.c expected was trivial. I will also be renaming the SKEY_fmt.c into SKEY_fmt_plug.c since now there is no requirement for -lskey to be there. IF the library IS found, john will link against it, and SKEY_jtr_plug.c will compile to a 0 byte .o file. But if that lib is not there, then SKEY_jtr_plug.c will do the work that -lskey was doing. It should be in bleeding jumbo within the hour.
