opmsg message encryption
PQ-safe userspace WireGuard® Implementation in Rust
A (WIP) API/VPN that uses military-grade encryption by implementing Perfect Forward Secrecy (PFS) and AES-256 encryption with ephemeral session keys.
🔐 End-to-end encrypted chat for Android. PQXDH (X25519 + ML-KEM-1024) + AES-256-GCM, full Double Ratchet (PFS + healing), P2P, Zero metadata, zero tracking.
Virgil Security Ratchet SDK provides an implementation of the Double Ratchet algorithm, which is used by parties to exchange encrypted messages based on a shared secret key.
Virgil PFS SDK Objective-C/Swift
Zyphor: A quantum-safe, fully anonymous chat protocol ensuring complete security and metadata protection.
Virgil Security Ratchet Objective-C/Swift SDK provides an implementation of the Double Ratchet algorithm, which is used by parties to exchange encrypted messages based on a shared secret key.
Versioned public Helix API in various languages/platforms, along with documentation and example use-cases
Test of libSodium's ChaCha20-Poly1305 with increases security by deriving a different key per message
(Moved to Fialka) 🔐 End-to-end encrypted chat for Android. PQXDH (X25519 + ML-KEM-1024) + AES-256-GCM, full Double Ratchet (PFS + healing), Firebase relay. Zero metadata, zero tracking.
Sanctum - A Secure P2P CLI chat that uses AES-256-GCM, X25519 ECDH for forward secrecy, and Argon2id. Built on SecCRY 3.0.0. No public build yet. (PolyForm Noncommercial License 1.0.0)
A high-performance, configurable post-quantum messaging engine SDK that's transport agnostic. Dynamically switch between blazing-fast symmetric streaming (Perfect Past Secrecy) and absolute per-packet asymmetric recovery (Perfect Forward Secrecy).
secure browser to browser instant chat with end to end multi-layer encryption utilizing perfect forward security
A secure client–relay–client messaging system implemented in Go, designed to provide mutual authentication, end-to-end confidentiality, message integrity, and forward secrecy over an untrusted relay using hashes for encryption.
🦀 Native Rust crypto core for Fialka. PQXDH + Double Ratchet + ML-DSA-44 + Ed25519. FFI bindings for Android, iOS & Desktop. Zero unsafe crypto.
Fork of go/x/crypto, providing an up-to-date OpenPGP implementation
Secure network Timestamping Service (TSS) in C with OpenSSL: ECDHE handshake with signed transcripts, AES-256-GCM authenticated session channel, and ECDSA-signed document timestamps. Includes client, iterative server, offline verifier, and account/volume management.
