hqc

This crate contains bindings to the C implementations of the following schemes, from PQClean.

This project packages Post-Quantum cryptographic algorithms that participate in the NIST PQC standardization effort. It is currently a collection of wrappers around C implementations from the PQClean project.

Included implementations from PQClean

Below is a list of the included schemes and the corresponding implementations sourced from PQClean. The "default" implementation is used in the Rust-friendly interface, alternative implementations are exposed as ffi methods only.

• hqc-128-1-cca2
  • leaktime (default)
• hqc-192-1-cca2
  • leaktime (default)
• hqc-192-2-cca2
  • leaktime (default)
• hqc-256-1-cca2
  • leaktime (default)
• hqc-256-2-cca2
  • leaktime (default)
• hqc-256-3-cca2
  • leaktime (default)

Notes

This implementation is not constant-time! This means that it is not secure.

This crate may remove the leaktime implementation at any point.
