That would be most welcome, right now the only gpu projects which support wpa are pyrit (dead) and oclhashcat (closed source). > >> 2) If aircrack can do it on cpu, and people are using it with john, >> there is no need for cpu wpapsk version in john? > No, there is: to simplify things for those people (one tool to use > instead of two), provide ability to interrupt/restore sessions with no > candidate passwords inadvertently skipped because of buffering, and > improve performance (JtR's format might eventually become faster). There are many reasons why this is good, right now we advocate using john to generate a wordlist to crack against, no point in piping the output from john into aircrack-ng when you can likely build a much faster cracker anyway. > >> 3) Do you think that we should abandon this format? - not a problem for me > No. On the contrary, I think that it is a desirable addition. Thank > you for your work on it! I agree, please don't abandon your work. I believe what needs to be done is a way to simplify cracking wpa with john. oclhashcat has some odd format it wants, a patch was accepted to aircrack-ng to output that file: aircrack-ng -J [hccap_name] [cap_clean_file] I would happily extend to you the same courtesy, if you find that the hashcat output format is unacceptable. I would also be willing to (attempt to) negotiate a format change so you could share an input format with hashcat and I don't need to have different output formats. Thanks for your hard work, we are all pleased so please do not feel deterred. -Zero_Chaos > >> 4) I do not understand what are you trying to tell me :) > The above - please continue to implement this.
