A sapling matures: meet sq 1.0

The Sequoia PGP project has announcedversion 1.0 of the sq command-line tool for managing OpenPGPencryption and signatures. It also provides a decentralized publickey infrastructure (PKI), and key management facilities. This isthe first stable release since development began on the project in2017.

sq's PKI is probably its most notable feature, and the one we investedthe most time in. The PKI is used to authenticate certificates, andmessages. Authentication is necessary to ensure that you areencrypting to the person you think you are, and to identify who reallyauthored a message; without authentication, encryption andverification are much weaker.
