libmceliece is a Classic McEliece microlibrary. libmceliece has a very simple stateless API based on the SUPERCOP API, with wire-format inputs and outputs, providing functions that directly match the KEM operations provided by Classic McEliece, such as functions
mceliece6960119_keypair
mceliece6960119_enc
mceliece6960119_dec
for the mceliece6960119
KEM.
Internally, libmceliece is based on the official Classic McEliece
software, specifically the vec
implementation (designed to work
portably across CPUs) and the avx
implementation (designed for higher
performance on Intel/AMD CPUs with AVX2 instructions). libmceliece
includes automatic run-time selection of implementations.
libmceliece is intended to be called by larger multi-function libraries (such as traditional cryptographic libraries), including libraries in other languages via FFI. The idea is that libmceliece takes responsibility for the details of Classic McEliece computation, including optimization, timing-attack protection, and (in ongoing work) verification, freeing up the calling libraries to concentrate on application-specific needs such as protocol integration. Applications can also call libmceliece directly.
