Encryption library used by Mail.io backend.

An extension to filippo.io/edwards25519 supporting hash-to-curve.

Elliptic curve Diffi-Helman (ECDH) key exchange protocol with curve25519 for V Language

A small library to do X25519 key agreement in C#

Cryptographic primitives for Cypherpunks that don't subscribe to "trust me bro" security assumptions

A Go implementation of an encryption system combining end-to-end encryption with ephemeral keys. It employs a three-layer key derivation process (K1, K2, K3) and generates time-based Ephemeral API Keys (EAPI). The system includes client-server key exchange, session management, and encrypted data transmission functionalities.

Xipher is a curated collection of cryptographic primitives put together to perform key/password based asymmetric encryption

End to end encrypted application using signal protocol

A pure-Rust implementation of the qDSA signature algorithm over Curve25519, plus X25519 and Elligator2.

Curve25519 contains X25519 and Ed25519 implementations.
