Rust High Concurrency Implementation of Oblivion, an End-to-End Encryption Protocol Based on ECDHE Encryption Algorithm

Elliptic Curve, Schnorr, and ZKP for Bitcoin. Supports iOS macOS tvOS watchOS visionOS + Linux.

PHP Secure Communications Library

Tests support and behavior of elliptic curve cryptography implementations on JavaCards (TYPE_EC_FP and TYPE_EC_F2M) and in selected software libraries.

The Heimdall Protocol offers robust device authentication mechanisms to secure the Industrial IoT devices with the assistance of smart contracts and ZK Proofs powered by blockchain technology. A Submission for Lisk Onchain Spring Hackathon.

wolfSSL SM cipher implementations

A free, open-source, robust yet user-friendly, compact and cross-platform tool for OpenPGP encryption. It stands out as an exceptional GUI frontend for the modern GnuPG (gpg).

R&D environment to study Cryptography so we can roll our own eventually

Open-source implementation of a substantial portion of the API of Apple CryptoKit suitable for use on Linux platforms.

SM2/SM3/SM4/ECDH crypto library based on OpenSSL.

Simple Go package to implement TOTP authentication functionality to the Go app. It supports ECDH as well.

Shows in a simple way how the sender and receiver function of Alice and Bob works in encrypted form. The ECDiffieHellman (ec key exchange) and ECDSA (ec digital signing) algorithms are used here. The elliptic curves are always selected randomly so that everything in the temporary area is used. Was slightly adapted in 2024 and updated to DotNet8.

pure-python ECDSA signature/verification and ECDH key agreement

Elliptic Curve Cryptography implementation of ECDH and ECDSA on curve secp256k1

Server / Client secure communication platform

Ed25519 signing, verification and encryption, decryption for arbitary files; like OpenBSD signifiy but with more functionality and written in Golang - only easier and simpler

Practical Cryptography for Developers: Hashes, MAC, Key Derivation, DHKE, Symmetric and Asymmetric Ciphers, Public Key Cryptosystems, RSA, Elliptic Curves, ECC, secp256k1, ECDH, ECIES, Digital Signatures, ECDSA, EdDSA

This project explores and implements various techniques and protocols using SageMath. It covers topics such as Elliptic Curve Diffie-Hellman (ECDH) key exchange, homomorphic encryption, secure multi-party computation (MPC), queueing theory analysis, and RSA cryptanalysis.
