GPG Cheat sheet

A small guide to little things

Create a key

gpg --gen-key

Sign a file

gpg -u {KEY_ID} --clearsign <file_name>

Move a key-pair privately

1. export the public and private keys and encrypt the pair:

   gpg --output - --export-secret-key {KEY_ID} | cat <(gpg --output - --export {KEY_ID}) - | gpg --armor --output keys.asc --symmetric --cipher-algo AES256

2. move the file (keys.asc) to the other computer.

3. import the key on the other computer:

   gpg --no-use-agent --output - keys.asc | gpg --import

4. shred the file for good measure:

   shred -n 3 -u keys.asc
