Crate sequoia_openpgpsource · [−]
OpenPGP data types and associated machinery.
This crate aims to provide a complete implementation of OpenPGP as defined by RFC 4880 as well as some extensions (e.g., RFC 6637, which describes ECC cryptography for OpenPGP. OpenPGP is a standard by IETF. It was derived from the PGP software, which was created by Phil Zimmermann in 1991.
This crate also includes support for unbuffered message processing.
A few features that the OpenPGP community considers to be deprecated (e.g., version 3 compatibility) have been left out. We have also updated some OpenPGP defaults to avoid foot guns (e.g., we selected modern algorithm defaults). If some functionality is missing, please file a bug report.
A non-goal of this crate is support for any sort of high-level, bolted-on functionality. For instance, RFC 4880 does not define trust models, such as the web of trust, direct trust, or TOFU. Neither does this crate. RFC 4880 does provide some mechanisms for creating trust models (specifically, UserID certifications), and this crate does expose those mechanisms.
We also try hard to avoid dictating how OpenPGP should be used. This doesn’t mean that we don’t have opinions about how OpenPGP should be used in a number of common scenarios (for instance, message validation). But, in this crate, we refrain from expressing those opinions; we will expose an opinionated, high-level interface in the future. In order to figure out the most appropriate high-level interfaces, we look at existing users. If you are using Sequoia, please get in contact so that we can learn from your use cases, discuss your opinions, and develop a high-level interface based on these experiences in the future.
Despite —or maybe because of— its unopinionated nature we found it easy to develop opinionated OpenPGP software based on Sequoia.
This crate implements functionality from RFC 4880bis, notably AEAD encryption containers. As of this writing, this RFC is still a draft and the syntax or semantic defined in it may change or go away. Therefore, all related functionality may change and artifacts created using this functionality may not be usable in the future. Do not use it for things other than experiments.
