Invitation to john-users team

john-users team was formed in the community of john-users mailing list and consists of enthusiasts of FOSS and of hash cracking then. So it is important for us to use only FOSS tools. We are looking for new active members who would fit into this atmosphere well. You need to be nice, active and ready to learn yourself. You don't need to be a great cracker or to have a lot of hardware. In the contest, ideas can help much more than raw hardware power.

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 value good sportsmanship and dislike cheating.
  • 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 why you think you would fit the team well),
  • preferred user name (only lower case letters and digits, please),
  • public ssh key (get a new key with 'ssh-keygen' command).
