CIRCL: Cloudflare Interoperable Reusable Cryptographic Library

Supersingular Isogeny-Based Cryptography constructions (python-code library)

SIKE for Java is a software library that implements experimental supersingular isogeny cryptographic schemes that aim to provide protection against attackers running a large-scale quantum computer.

Java implementation of the Supersingular Isogeny Diffie-Hellman key exchange

This software library is a C-language + optimized assembly code that supports an instance of the Super-Singular Isogeny Diffie-Hellman (SIDH) algorithm.
