frodo

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.

• frodokem640aes
  • opt (default)
  • clean (included as ffi only)
• frodokem640shake
  • opt (default)
  • clean (included as ffi only)
• frodokem976aes
  • opt (default)
  • clean (included as ffi only)
• frodokem976shake
  • opt (default)
  • clean (included as ffi only)
• frodokem1344aes
  • opt (default)
  • clean (included as ffi only)
• frodokem1344shake
  • opt (default)
  • clean (included as ffi only)

Notes

If you use it via the FFI interface: The clean implementation of Frodo needs a lot of stack space, specify env variable RUST_MIN_STACK to make sure it has enough stack space in threads.

This is not relevant for the 'normal' api methods.
