rPGP

New release: #rPGP version 0.20.0 🧰🔐

https://github.com/rpgp/rpgp/releases/tag/v0.20.0

#OpenPGP implemented in pure #Rust, permissively licensed

This release changes the default decryption behavior for SEIPDv1 messages to MDC-check first.
While this can be less efficient for large messages, it is a defensive best practice (see https://github.com/rpgp/rpgp/issues/662).

It also includes various bug fixes for stability, and improved build speed.

Finally, the release adds all functionality from draft-wussler-openpgp-forwarding.

A few days ago, RFC 9980 ("Post-Quantum Cryptography in #OpenPGP") has been finalized 🎉

#rPGP features full support for this draft since v0.16.0, and we're excited that #PQC in OpenPGP is now ready for production use.

The rPGP-based SOP CLI tool https://crates.io/crates/rsop comes with PQC support enabled by default in the new v0.11.0

rsop can be seen in the "OpenPGP interoperability test suite" at
https://sequoia-pgp.gitlab.io/openpgp-interoperability-test-suite/results.html (listed as "rpgpie"), including full interop for PQC artifacts.

New release: #rPGP version 0.17.0 🧰🔐✨

https://github.com/rpgp/rpgp/releases/tag/v0.17.0

#OpenPGP implemented in pure #Rust, permissively licensed

One highlight of this release is improved performance for encryption and decryption (saving time and/or battery when handling larger messages).

The release also features many small improvements to the rPGP API, and various bugfixes (see link above for details). Finally, it adds support for decryption of a #GnuPG-proprietary message format.

New release: #rPGP version 0.16.0 🧰🔐✨

https://github.com/rpgp/rpgp/releases/tag/v0.16.0

#OpenPGP implemented in pure #Rust, permissively licensed

This release features streaming message support: Now rPGP can process arbitrarily large messages, with modest memory requirements.

It adds experimental support for the upcoming OpenPGP #PQC IETF standard https://datatracker.ietf.org/doc/html/draft-ietf-openpgp-pqc

This release also brings various improvements for key generation, support for X448/Ed448, and many minor fixes.

Announcing this here with some delay: #rPGP 0.18.0 (from Nov 2025) contained only minor changes, representing mostly cleanup work (however, some of the resulting API changes were formally semver breaking).

See https://github.com/rpgp/rpgp/releases/tag/v0.18.0 for a summary of the release.

rPGP is an #OpenPGP implementation in pure #Rust (https://crates.io/crates/pgp).

It serves as the end-to-end encryption engine for Delta Chat:
@delta@chaos.social, a secure decentralized messager for all major platforms (and then some).

rPGP implements all generations of the OpenPGP standard, up to and including the new RFC 9580.

Other changes include:

• The key material-related traits have been reworked.
• The representation of timestamps has been simplified.
