classicmceliece

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.

Serialization

If you want serde support, enable the serialization feature.

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.

Notes

This implementation requires a lot of stack space. You need to specify RUST_MIN_STACK=800000000, probably.
