We have just released version 0.17.0 of Sequoia. The release includes
the low-level crate `sequoia-openpgp`, a program to verify detached
signatures geared towards software distribution systems called `sqv`,
and a new commandline frontend for Sequoia implementing the [Stateless
OpenPGP Command Line Interface] `sqop`.
[Stateless OpenPGP Command Line Interface]: https://datatracker.ietf.org/doc/draft-dkg-openpgp-stateless-cli/
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].

If you use Sequoia, please port your code to the latest version and
report any problems you encounter. Thank you.
# SOP primer
To demonstrate SOP, let's generate a key, and encrypt and decrypt a
message:
$ sqop generate-key julia(a)example.org > julia.secret.pgp
$ sqop extract-cert < julia.secret.pgp > julia.public.pgp
First, we generate a key for `julia(a)example.org`. Next, we extract
the certificate, i.e. the key without the secret key material.
$ 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.
