Library for elliptic curves cryptography

A compact portable X25519 + Ed25519 implementation

Public key cryptography library for Ruby providing the X25519 Diffie-Hellman function

Updated! (Dec2-2019) This is a C-language software library that provides optimized implementations of the Diffie-Hellman functions known as X25519 and X448 (RFC-7748) for 64-bit architectures.

SIMD Vectorized implementation of X25519, Ed25519, X448 and Ed448

Diglol Crypto for Kotlin Multiplatform.

cryptographic library for ed25519 and curve25519

An ENGINE gluing together OpenSSL and NaCl-derived crypto.

Elliptic Curve Point compression/decompression for mbedtls

O(1) Cryptography is an easy to use, hard to misuse Java cryptographic library based on O(1) cryptographic algorithms

Lightweight cryptography

Example of private, public key generation and shared secret derivation using OpenSSL and the x25519 curve.

An Embedded Cryptography Library

Ephemeral Diffie-Hellman Over COSE (EDHOC), a compact, and lightweight authenticated Diffie-Hellman key exchange with ephemeral keys that can be used over any layer.

Rust bindings for HACL* / EverCrypt (high assurance crypto)

Vulkan based TOR v3 Hidden Service vanity address generator.

Pretty good privacy, but not PGP.

Curve25519 contains X25519 and Ed25519 implementations.

Minimal X25519 (Curve25519) key exchange for embedded systems — pure C99, zero dependencies, zero allocations. Pairs with microcrypt.
