Sequoia is a comprehensive OpenPGP implementation written in Rust. It provides reusable components for applications that need to create, inspect, encrypt, decrypt, sign or verify OpenPGP data, together with command-line tools for users who want those capabilities directly.
The project implements modern OpenPGP specifications while retaining support for the older standard where compatibility is required. Its design separates low-level packet and message handling from higher-level policy decisions, allowing applications to decide how certificates, signatures and trust information should be treated.
This is free and open source software.
Key Features
- Implements OpenPGP as defined by RFC 9580 and RFC 9980, with compatibility for the deprecated RFC 4880 standard.
- Provides the sq command-line frontend for encryption, decryption, signing, verification and certificate management.
- Includes sqv for focused detached-signature verification with configurable validation requirements.
- Offers Rust crates for OpenPGP processing, certificate storage, keystore access, networking and web-of-trust operations.
- Supports unbuffered message processing so applications do not need to load complete messages into memory.
- Uses a policy framework so applications can define acceptable algorithms and validation rules.
- Uses modern algorithm defaults and omits some obsolete compatibility features considered unsafe or unnecessary.
- Provides a C API for integrating selected Sequoia functionality into software outside the Rust ecosystem.
