CSIDH

Crate API

Pure Rust implementation of the CSIDH cryptographic algorithm for secret key exchange. Provides a no_std-friendly implementation. Not constant-time yet.

CSIDH-512, CSIDH-1024 and CSIDH-1792 are available. Custom parameters are also supported.

The current implementation is far from being as fast as the state of the art implementations. Work is underway to improve its efficiency.
