Ed25519 certs, quantum-seeded keys

Modern TLS is moving to smaller, faster elliptic-curve keys. Migration takes time — start now.

Quickstart — issue a cert from the API

# 1. Create an API key in your dashboard → API Keys export QNTYX_KEY="qntyx_ca_…" # 2. Issue a quantum-attested certificate curl -X POST https://ca-api.qntyx.io/certificates/issue \ -H "Authorization: Bearer $QNTYX_KEY" \ -H "Content-Type: application/json" \ -d '{"common_name": "example.com", "valid_days": 90}'

Same key works from any language — it is just an HTTP header.

Certificate Types

TLS / HTTPS

Secure your web servers with Ed25519 certificates. SAN support for multiple domains.

Client Auth (mTLS)

Mutual TLS for service-to-service authentication. Zero-trust architecture with quantum-attested client certificates.

Code Signing

Sign software releases with quantum-attested certificates. Prove provenance of binaries, containers, and packages.

IoT / Device

Lightweight Ed25519 certificates for embedded devices. 32-byte keys vs 256-byte RSA — ideal for constrained hardware.

Quantum Attestation

Every certificate issuance is quantum-attested — cryptographic proof the certificate was issued at a specific moment in time, anchored to quantum entropy. Verify any attestation publicly without an account.
