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 for hash cracking; you don't want to use non-free software for hash cracking including freeware, shareware, closed-source and so on.
  • You are a subscriber of john-users mailing list, or you were invited by a member.

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 the following info:

  • who invited you, or how long you are on john-users mailing list, (or give a reason to trust you ;-) ),
  • preferred user name (only lower case letters and digits, please),
  • public ssh key (get a new key with 'ssh-keygen' command).
