pychloride 0.7.18.1

Pyodide-compatible ctypes interface for libsodium (refactored pysodium)

pychloride

Pyodide-compatible ctypes interface for libsodium. This is a refactored pysodium wheel designed specifically for WebAssembly environments.

Installation

For Pyodide/PyScript

import micropip
await micropip.install("pychloride")

For standard Python (if you have libsodium installed)

pip install pychloride

Usage

import pychloride

# Generate a keypair
pk, sk = pychloride.crypto_box_keypair()

# Sign a message
sign_pk, sign_sk = pychloride.crypto_sign_keypair()
signature = pychloride.crypto_sign_detached(b"Hello World", sign_sk)

Differences from pysodium

• Bundles a WebAssembly-compiled libsodium.so for use in Pyodide
• Includes explicit argtypes definitions for ctypes WASM compatibility
• Loads libsodium from the package directory instead of system paths

Versioning

The version follows the pattern X.Y.Z.P where:

• X.Y.Z is the upstream pysodium version
• P is the pychloride patch version
