Choose a UID

  • Use a valid e-mail address: no obfuscation.
  • The e-mail address should be reliable (do not use one you got from your ISP or a random free service).
  • When in doubt, you should prefer using your @archlinux.org address.
  • The UID also has to be the same as the PACKAGER variable you use to build packages.
  • A correct UID looks like this: Pierre Schmitz <pierre@archlinux.de>
  • We strongly advise you use your real name. It has to be exactly that found on official documents (passport, driver's license, etc.); see CAcert's practice on names.

Create a key pair

  1. Install gnupg.
  2. Run: gpg --gen-key
    1. You may use the default: a never expiring 2048-bit RSA key for encryption and signing.
  3. Create a revocation certificate, for use when/if your private key ever gets compromised:
    1. Run: gpg -o ~/.gnupg/pierre@archlinux.de-revoke.asc --gen-revoke pierre@archlinux.de
    2. Make sure to store this file in a secure location (and/or encrypt it with a passphrase); then delete the plaintext version.
  4. Backup your private key: gpg --export-secret-keys pierre@archlinux.de > pierre@archlinux.de-private.asc

Recommended: Get your key signed by CAcert

  1. Create an account on CAcert.
  2. Meet CAcert assurers and have them verify your official identification documents; see CAcert's assurance policy.
  3. You will then be able to access a new part of the CAcert website and get your key signed:
    1. Export your public key: gpg --export --armor pierre@archlinux.de > pierre@archlinux.de.asc
    2. Paste the content of that file into the form on the CAcert website.
    3. Save the signed key from the CAcert website and import it: gpg --import <filename>

Recommended: Get your key signed by other devs

  1. When ever you meet with another dev, sign each others' keys.
  2. Take this seriously: never sign a key when you cannot verify the other person's identity.
  3. See CAcert's assurance policy for good guidelines.

Publish your public key

  1. Send your public key to a keyserver:
    1. Check your key id with: gpg -k
    2. Run: gpg --send-keys KEY-ID
  2. Add your key fingerprint to your profile at https://www.archlinux.org/devel/profile/

Be safe!

  1. Create a backup of your keys and be sure not to forget the passphrase!
