`gpg --encrypt --sign --recipient {{alice@example.com}} --recipient {{bob@example.com}} {{doc.txt}}`

- Encrypt `doc.txt` with only a passphrase (output to `doc.txt.gpg`):

`gpg --symmetric {{doc.txt}}`

- Decrypt `doc.txt.gpg` (output to `stdout`):

`gpg --decrypt {{doc.txt.gpg}}`

- Import a public key:

`gpg --import {{public.gpg}}`

- Export public key for alice@example.com (output to `stdout`):

`gpg --export --armor {{alice@example.com}}`
