Open Source Rust Cryptography Software

Stegcore combines cryptography and steganography to hide encrypted data inside ordinary files. It encrypts your payload before embedding it, so the hidden content is unreadable even if someone extracts it, and invisible to anyone who doesn't know it's there. Unlike basic steganography tools that hide data without encrypting it, Stegcore ensures the payload is cryptographically protected at rest. Unlike pure encryption tools, the payload isn't even visible. Designed for journalists, security researchers, red teamers, digital forensics professionals, and CTF participants.

Fast. Private. Together. — Send it. It's there. Engineered by Thisma Labs. Beside is a local-first peer sharing app for Windows 10/11 and Android 8.0+.

Key Features & Specifications: - Mutual TLS 1.3: End-to-end encrypted with pinned SPKI SHA-256 device keys. - 8-Digit SAS: RFC 8446 TLS Exporter pairing prevents Wi-Fi MITM attacks. - Hardware Keystore: Private keys encrypted in Windows DPAPI & Android Keystore. - Bounded 64 KB RAM: Stream multi-GB files with per-file SHA-256 verification. - OS Integration: System tray, Explorer "Send with Beside", and Android Share Sheet. - Free vs Pro: Free tier included; Pro unlocks unlimited sizes, folders, & Auto-Accept.

s2n-quic is AWS’s open-source implementation of the IETF QUIC transport protocol, written in Rust and designed for performance, security, and modern usage. QUIC is a UDP-based, multiplexed, encrypted transport layer that underpins HTTP/3 and addresses issues such as head-of-line blocking and faster handshake times compared to TCP+TLS. This library integrates with AWS’s s2n-tls or rustls for the TLS 1.3 handshake and leverages Rust’s memory and thread safety guarantees to deliver a robust implementation. It is built with configurability in mind—you can tune congestion control (like CUBIC), pacing, packet size discovery, and other advanced network behaviors. Extensive testing (unit, fuzz, interop) ensures protocol compliance and interoperability with other implementations. Because it is open-source under Apache 2.0, organizations can integrate it into services where low latency, multiple streams, or mobility (connection migration) matter.

Codegroup is a Java application that will allow one to convert binary (or text) computer files in to 5 letter codegroups for transmission over email, landline telephones, radioteletype or Morse Code. Codegroup has internal error correction & limited cryptography capabilities.

High-performance cryptography for proof systems and blockchain protocols. This library provides a constant-time implementation of cryptographic primitives with a particular focus on cryptography used in blockchains and zero-knowledge-proof systems. The library aims to be a fast, compact and hardened library for elliptic curve cryptography needs, in particular for blockchain protocols and zero-knowledge proofs system.

KEIBIDROP opens a folder on another computer over the internet as if it were a folder on your own computer. This mode is called Teleport: you open and edit the files right away, and each file streams only when an application opens it, so there is no wait for an upload or a download. KEIBIDROP also sends files between two devices with no account and no file size limit, and a dropped connection resumes where it stopped. It runs on Windows, macOS, Linux and Android, and the other person can join from a browser at https://web.keibidrop.com with nothing installed. Every connection is end-to-end encrypted with a post-quantum key exchange (X25519 and ML-KEM-1024). The engine and the desktop app are open source under AGPL-3.0-only at https://github.com/KeibiSoft/KeibiDrop, and the installers are at https://keibidrop.com/install.html.

A cryptographically verifiable code review system for the cargo (Rust) package manager. cargo-crev is an implementation of Crev as a command-line tool integrated with cargo. This tool helps Rust users evaluate the quality and trustworthiness of their package dependencies. Crev is a language and ecosystem agnostic, distributed code review system. Use reviews produced by other users. Increase the trustworthiness of your own code. Build a web of trust of other reputable users to help verify the code you use. Static binaries are available from the releases page. Crev is a system for verifying the security and reliability of dependencies based on collaborative code reviews. Crev users review the source code of packages/libraries/crates and share their findings with others. Crev then uses Web of Trust to select trusted reviews and judge the reputation of projects' dependencies.
