ASCII sign a PGP key

ascii_sign is a script that takes a filename and a target key id as input. It downloads the target key, then generates a new PGP for each line in the file. It signs the target key with the new keys and pushes everything to the key server. Essentially, it lets you sign any key with ASCII art.

For example, check out my key:

ASCII sign a key like this:


If you're ASCII signing a key with multiple user IDs, you'll have to press "y" to verify you want to sign all user IDs for each line.

Add fake sigs to a PGP key is a script that takes a name, email address, and target key id as input. It creates a new key with that name and email, and uses it to sign the target key.

For example, if you want Barack Obama to sign your key, it's easy:

./fake_sign [NAME] [EMAIL] [KEYID]

Brute force PGP key ID (slow) brute forces key IDs by generating an RSA key (using ssh-keygen) and uses the script keytrans to turn it into a PGP key, but changing the timestamp. To run it on your computer, making it a very high priority process:

nice -20 ./bruteforce_keyid [KEYID] [USERID]
