About Sequoia PGP
Sequoia is a modular implementation of the OpenPGP standard, written in the memory-safe Rust language, with a focus on safety and correctness. Besides the library it provides sq, a command-line tool for encrypting, decrypting, signing and verifying data and for managing keys.
The project also works on the wider OpenPGP ecosystem rather than just reimplementing one program. It suits developers and command-line users who want a modern alternative to GnuPG, and projects that need an OpenPGP library they can build into their own software.
Strengths
- Written in memory-safe Rust
- Usable both as a library and through the sq command-line tool
- Designed with a focus on security and correctness
Limitations
- Command-line only, with no graphical interface

Sequoia PGP as an alternative
Listings that name Sequoia PGP as an alternative.
age
File encryption with one small key, no options to get wrong, and a command you can remember.
Sequoia PGP offers OpenPGP encryption, signing and key management in memory-safe Rust through the sq tool, but it is listed for Linux only and is aimed at developers.
Kryptor
Command-line file encryption and signing using modern cryptography.
Sequoia PGP provides OpenPGP encryption, signing and key management through the sq command, written in Rust, and is available on Linux rather than all desktop systems.
rage
A Rust implementation of the age file encryption format, with a command-line tool and library.
Sequoia PGP is another Rust tool, but implements OpenPGP with signing and key management through sq, so it works with existing PGP keys.
