List Keys

You can list all the GPG keys with the following command.

gpg --list-keys

Export Key

Change “keyID” to your key idea from the above command. The key ID is the long string of hexadecimal characters.

gpg --export-secret-keys "keyID" > private_key.asc

This will export the keys to private_key.asc. Rename as appropriate.

To export the Public Key

gpg --export "keyID" > public_key.asc

Import Key

To use the key, you’ll need to import and trust the key.

gpg --allow-secret-key-import --import private_key.asc
gpg --edit-key "keyID"

Then type

trust

Select level 5.

Import the Public Key

gpg --import public_key.asc

Decrypt Files

To decrypt a single file do

 gpg --batch --passphrase='password' ./file.gpg

If your GPG does not have a password, remove the whole `–passphrase=’password’` option

To decrypt multiple files you can run

for file in * ; do gpg --batch --passphrase='password' "$file" ; done
