FIPS 203 / 204 / 205
Post-Quantum Security Layer
The foundation of all post-quantum security. SDK and library to integrate quantum-safe cryptography into any application.
Quick Start
Integrate post-quantum security in minutes with our simple API.
Python
from pqsl import get_pqsl
pqsl = get_pqsl()
# Gerar par de chaves
keypair = pqsl.generate_keypair()
# Encriptar
encrypted = pqsl.encrypt_data(
data=b"dados sensÃveis",
recipient_public_key=keypair.public_key
)
# Desencriptar
decrypted = pqsl.decrypt_data(
encrypted_data=encrypted,
private_key=keypair.private_key
)NIST Algorithms
All NIST-approved algorithms for the post-quantum world.
ML-KEM-768
FIPS 203Lattice-based key encapsulation. Replaces RSA/ECDH.
ML-DSA-87
FIPS 204Lattice-based digital signatures. Replaces RSA/ECDSA.
SLH-DSA-256
FIPS 205Hash-based stateless signatures. Conservative alternative.
Python Decorators
