Invitation to john-users team

Requirements to participate on john-user team:
  • you have some basic skills: file copying over ssh, basic usage of john, irc, mailing (it is ok to learn it on your own before or during the contest),
  • you'd like to use John the Ripper or other FOSS tool; you don't want to use non-free software including freeware, shareware, closed-source and so on.

The team uses a server to collaborate during the contest. So every member needs an user account there.

So if you would like to participate send a private mail to Aleksey Cherepanov[1] with 2 following things:

  • preferred user name (only lower case letters and digits, please),
  • public ssh key (get a new key with 'ssh-keygen' command).
