pyoqs-wasm 0.15.1.0

Pyodide-compatible ctypes interface for Open Quantum Safe liboqs

pyoqs-wasm

Pyodide-compatible ctypes interface for Open Quantum Safe (liboqs). This is a refactored liboqs-python wheel designed specifically for WebAssembly environments.

Installation

For Pyodide/PyScript

import micropip
await micropip.install("pyoqs-wasm")

For standard Python

pip install pyoqs-wasm

Usage

import oqs

# List available KEM algorithms
print(oqs.get_enabled_kem_mechanisms())

# Key Encapsulation
with oqs.KeyEncapsulation("ML-KEM-768") as kem:
    public_key = kem.generate_keypair()
    ciphertext, shared_secret_enc = kem.encap_secret(public_key)
    shared_secret_dec = kem.decap_secret(ciphertext)

# Digital Signatures  
with oqs.Signature("ML-DSA-65") as signer:
    public_key = signer.generate_keypair()
    signature = signer.sign(b"Message to sign")
    is_valid = signer.verify(b"Message to sign", signature, public_key)

Differences from liboqs-python

• Bundles a WebAssembly-compiled liboqs.so for use in Pyodide
• Includes explicit argtypes definitions for ctypes WASM compatibility
• Loads liboqs from the package directory instead of attempting auto-install

Versioning

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

• X.Y.Z is the upstream liboqs-python version
• P is the pyoqs-wasm patch version
