An implementation of the Stateless OpenPGP Command Line Interface using Sequoia.

This implements a subset of the [Stateless OpenPGP Command Line Interface] (SOP) using the Sequoia OpenPGP implementation. While SOP is not intended for daily use, it is a good way to interact with and explore OpenPGP implementations. SOP is primarily used as abstraction in the [OpenPGP interoperability test suite].

SOP primer

To demonstrate SOP, let's generate a key, and encrypt and decrypt a message:

sh $ sqop generate-key julia@example.org > julia.secret.pgp $ sqop extract-cert < julia.secret.pgp > julia.public.pgp

First, we generate a key for julia@example.org. Next, we extract the certificate, i.e. the key without the secret key material.

sh $ echo "a message" | sqop encrypt julia.public.pgp > message.pgp $ sqop decrypt julia.secret.pgp < message.pgp a message

Here, we encrypt a message with Julia's certificate, and decrypt it with her key.
