Core Capabilities

Built on the principle that trust should be mathematical, not institutional.

Memory-Hard KDF

Utilizes Argon2id with tunable memory costs to make GPU brute-force attacks economically impossible.

High Throughput

Optimized for modern multi-core processors. Encrypt gigabytes of data in seconds with SIMD acceleration.

Stateless Integrity

Self-contained .qenc file format. No external databases or key servers required for restoration.

Developer API

Integrate QuantumPy directly into your Python workflows. Our library exposes simple, safe interfaces for complex cryptographic operations.

Type-safe configurations
Automatic salt & nonce management
Stream-based processing for large files
