Find a type or operation.

Choose a 0.9.0 crate reference, or build the API for the pinned source guide.

Scheme APIs

Crate	Use it for
poulpy-ckks	Encoding, encrypted numerical arithmetic, polynomial evaluation, and bootstrapping
poulpy-bin-fhe	Blind rotation, circuit bootstrapping, and encrypted integer arithmetic
poulpy-mhe	Multiparty key generation, key switching, and share conversions

Start with the CKKS or Binary FHE guide if you are looking for a runnable example.

Core and hardware abstraction

Crate	Use it for
poulpy-core	Ciphertexts, keys, encryption, and scheme-independent operations
poulpy-hal	Backend layouts, operation traits, and scratch memory

The codebase overview explains the dependency direction and extension points.

Backend APIs

These links cover the available published CPU backend APIs. Poulpy’s backend interface is hardware-independent, and a GPU backend is in active development. See Hardware targets for the broader scope.

Portable
AVX2 / FMA source — the docs.rs build failed at 0.8.3 and is not yet rechecked for 0.9.0; generate the pinned reference locally with the command below
AVX-512 / IFMA
ARM NEON

For AVX2/FMA documentation from the pinned checkout:

RUSTFLAGS="-C target-feature=+avx2,+fma" cargo doc --locked --no-deps -p poulpy-cpu-avx --features enable-avx,enable-ckks --open

Match the reference to your checkout

The links above target the 0.9.0 APIs. Technical guides and examples use the pinned source baseline. Use the version selector for another published dependency version. For a source checkout, you can generate the reference for the exact code you are using:

cargo doc --locked --no-deps -p poulpy-hal -p poulpy-core -p poulpy-cpu-portable -p poulpy-ckks -p poulpy-bin-fhe --features poulpy-cpu-portable/enable-ckks --open
