Post-Quantum Security Layer

The foundation of all post-quantum security. 12 languages, 8 middlewares, simple integration into any stack.

Post-Quantum Algorithms

Implementation of NIST-standardized algorithms for post-quantum cryptography.

ML-KEM-768

FIPS 203

Lattice-based key encapsulation. Replaces RSA/ECDH with quantum-resistant security.

ML-DSA-87

FIPS 204

Lattice-based digital signatures. Replaces RSA/ECDSA with post-quantum protection.

SLH-DSA-256

FIPS 205

Hash-based stateless signatures. Conservative alternative with long-term guarantees.

Python Decorators

Protect functions with a single line of code.

@pqsl_protected() — Full protection

@pqsl_sign_only — Digital signature only

@pqsl_database — Database operations

@pqsl_api — Secure REST endpoints

@pqsl_file — File protection

@pqsl_stream — Secure streaming

Native PQC integration in the most used communication protocols.

TTL-PQC

Automatic post-quantum key rotation on critical endpoints. Each key has a configurable minimum time-to-live (30 s to 24 h), killing the "harvest-now, decrypt-later" risk at the root.
