Qopanza

Qopanza is a quantum-safe cryptography platform that finds quantum-vulnerable cryptography in software and replaces it with NIST post-quantum standards through one API.

What it does

Qopanza scans source code, dependencies and TLS endpoints. It builds an inventory of the cryptography an application depends on and ranks it by quantum risk. Developers call the Qopanza API to encrypt and sign with ML-KEM, ML-DSA and SLH-DSA, or with hybrid X25519 + ML-KEM-768. SDKs cover Python, TypeScript, Go, Rust, Java, C#, Ruby, PHP and C++. With managed keys, Qopanza holds the keys, rotates them and records every use. In zero-knowledge mode, the user keeps the private key and registers only the public half. Qopanza can then inventory those keys but cannot decrypt anything. The inventory can be turned into a migration plan that the user approves and tracks.

Capabilities

  • Managed keys come with rotation and revocation, and every decryption is recorded against the API key that asked for it.
  • The inventory, risk score and CycloneDX CBOM export are available for scanned cryptography.
  • A hash-chained audit log records key operations, and the chain can be verified by the user.
  • Claude, Cursor and Codex can call Qopanza directly through its AI agent (MCP) integration.
  • A free app security scan names leaked API keys, open databases and missing protections in apps built with AI tools such as Lovable, Bolt and Cursor, with no account needed.

When to use it

  • You need to replace RSA and elliptic-curve cryptography with post-quantum standards.
  • You need a list of which cryptography your software uses and where it is used.
  • You need to show customers and auditors where you stand on quantum-safe cryptography.
