CORE FEATURES

Built for Quantum Resilience

Everything you need to encrypt, sign, and manage post-quantum keys without the complexity.

Post-Quantum Ready

NIST-standardized Kyber768 (ML-KEM-768) and Dilithium3 (ML-DSA-65) algorithms protect your data against both classical and quantum attacks.

Non-Exportable Keys

Private keys never leave our secure enclave. All cryptographic operations happen server-side, eliminating key leakage risk entirely.

Simple REST API

Encrypt, decrypt, sign, and verify with straightforward API calls. No cryptography expertise required. SDKs for Python, Node.js, and Go.

WHO IT'S FOR

Trusted Across Industries

From government agencies to healthcare providers, organizations use Qpher to future-proof their encryption against quantum threats.

Government & Defense

Protect classified documents and diplomatic communications against harvest-now-decrypt-later attacks. NIST FIPS 203/204 compliant for federal mandates.

Financial Services

Secure banking records, KYC data, and transactions for decades. Quantum-safe key encapsulation keeps sensitive files on your infrastructure.

Healthcare

Encrypt PHI and sign medical records with quantum-resistant algorithms. Non-exportable keys and audit trails satisfy HIPAA requirements.

HOW IT WORKS

Three Steps to Quantum Safety

Go from sign-up to your first encrypted payload in under five minutes.

Sign Up

Create a free account and get your API key. No credit card required.

Integrate

Install our SDK or call the REST API directly. We handle key generation and lifecycle.

Encrypt

Send plaintext, receive quantum-safe ciphertext. Your data is protected against harvest-now-decrypt-later attacks.

DEVELOPER EXPERIENCE

Integrate in Minutes

Simple SDK. Familiar patterns. Get started with just a few lines of code.

import requests

response = requests.post(
    "https://api.qpher.ai/api/v1/kem/encrypt",
    headers={
        "x-api-key": "qph_live_abc123...",
        "Content-Type": "application/json",
    },
    json={
        "plaintext": "SGVsbG8gUXVhbnR1bSBXb3JsZA==",
        "key_version": 1,
    },
)

data = response.json()["data"]
print(data["ciphertext"])  # base64-encoded quantum-safe ciphertext
