Prepare your GNU/Linux system for the cp4j

To install software under GNU/Linux systems is fairly straightforward.

Short Remarks

With this approach, you 'll install or update the following software at once:

  • GnuPG - The Gnu Privacy Guard - A free tool for secure communication and data storage.
  • GnuPG2 - Another free GnuPG version.
  • GPA - The GNU Privacy Assistent - A free graphical program for key management.
  • pidgin - A free multi-platform chat-client.
  • pidgin-otr - A free plugin, that keeps your chats private.
  • keepass - A free program for secure password management.
  • Thunderbird or Icedove - A free e-mail client, that interacts with enigmail (see: below).
  • Enigmail - A free plugin, that automatically decrypts and verifies your e-mail.

If the software already exists on your system, it simply updates or doesn't get installed. Files like private keys or public keys won't get overwritten.

Ubuntu and *buntus

On distributions like Ubuntu, Kubuntu, Xubuntu or Mint, do the following:

  1. Open a terminal window
    • You can do this by pressing CTRL+ALT+T on your keyboard simultaneously, or
    • by clicking: Applications > Accessories > Terminal
  2. Type: 
    sudo apt-get update
  3. It will ask for your password. Type it in and press ENTER to continue.
  4. Now type: 
    sudo apt-get install gnupg gnupg2 gpa keepass2 pidgin pidgin-otr thunderbird enigmail
  5. Perhaps it will ask for your password again. If not, just press ENTER to continue. If it does, type it, and then press ENTER to continue.
  6. Press y to continue. Let the machine do the installing.
  7. Type: 
    exit

Congratulations. Your software is now either updated or freshly installed. Now participate in the next cryptoparty to get used to using it. Have fun!
