Install some dependencides. On a Debian-based distro you do this:
sudo apt-get install python-psutil monkeysphere
Install the gnupg build dependencies. On a Debian-based distro you do this:

ASCII sign a PGP key
9 years ago
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 and signs the target key with the new keys. 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
9 years ago 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. Usage:
./fake_sign [NAME] [EMAIL] [KEYID]
Brute force PGP key ID
---------------------- is a modified version of the keytrans script, that comes with [monkeysphere]( that adds new functionality to do the brute forcing. Since:
fingerprint = hash(public_key)
public_key = timestamp + public_key_data
fingerprint = hash(timestamp + public_key_data)
So the script works like this:
* It generates a 4096 bit RSA key
* It sets the creation timestamp to now
* It goes in a loop calculating the fingerprint and looking for collisions, decrementing the timestamp until the timestamp is from 3 years ago
* If it didn't find it, it starts over by generating a new 4096 bit RSA key
On my laptop it compares about 12,000 fingerprints per second. Here's how to use it:
./bruteforce_keyid [USERID] [KEYID]
