SIDH Library is a fast and portable software library that implements state-of-the-art supersingular isogeny cryptographic schemes. The chosen parameters aim to provide security against attackers running a large-scale quantum computer, and security against classical algorithms.
I slightly changed SIDH.h and makefile to build the web version using emscripten. My changes here: https://github.com/procoru/PQCrypto-SIDH/commit/539c0f2d5e14682d3cf1a893e4753423e0ce592a
