Proton Cryptography Rust

This workspace provides several utility crates for cryptographic operations within Proton.

Core Proton Crypto

The proton-crypto crate contains the core library for crypto operations. In particular:

• It defines a generic API for OpenPGP operations, which is the core cryptographic protocol in most products. An implementation of the API can be accessed through new_pgp_provider providing a default PGPProvider.
• An implementation of the PGPProvider using GopenPGP via the gopenpgp-sys wrapper.
• SRP API for authentication and an implementation using GopenPGP via the gopenpgp-sys wrapper. The default SRP provider can be accessed via new_srp_provider.

Account Proton Crypto

The proton-crypto-account crate provides Proton key models (e.g., User Keys, Address keys, etc.) and key management operations building on proton-crypto. Note that the crate re-exports the underlying proton-crypto dependency.

Others

proton-srp

A pure Rust implementation of Proton's version of the Secure Remote Password (SRP) protocol.

gopenpgp-sys

Rust API calling GopenPGP.

proton-device-verification

Implements device verification for clients.
