samp-crypto
Native crypto backend for samp-core, the Python SDK for the Substrate Account Messaging Protocol (SAMP).
This package exposes the SAMP cryptographic primitives — sr25519 key agreement, HKDF-SHA256 key derivation, and ChaCha20-Poly1305 sealing — as a compiled extension module built with PyO3 and maturin. It is not meant to be used directly; install samp-core instead.
Install
pip install samp-core
samp-crypto is pulled in automatically as a dependency.
What it provides
A single extension module, samp_crypto, with stateless functions covering:
- sr25519 key derivation from a 32-byte seed
- Sealed message encryption to a recipient public key (per the SAMP capsule format)
- Group capsule wrapping and unwrapping
- View-tag derivation for inbox scanning
The protocol details are specified in the SAMP specification.
Supported platforms
Wheels are published for:
- CPython 3.9+ on Linux (x86_64, aarch64), macOS (x86_64, arm64), and Windows (x86_64)
A source distribution is also published; building from source requires a stable Rust toolchain.
