Quantum-Safe Cryptography, Simplified
Full post-quantum key management, encryption, and digital signatures as managed APIs. No cryptography expertise required — we handle key generation, rotation, and storage so you can focus on your product.
PLATFORM CAPABILITIES
Enterprise-Grade PQC Infrastructure
Everything you need to protect data against quantum threats.
Kyber768 KEM Encryption
NIST FIPS 203 (ML-KEM-768) key encapsulation mechanism. Encrypt data with quantum-resistant keys at sub-15ms latency. Hybrid KEM-DEM scheme combines Kyber768 with HKDF-SHA256 and AES-256-GCM for payload encryption of any size.
Dilithium3 Digital Signatures
NIST FIPS 204 (ML-DSA-65) digital signature scheme. Sign documents, invoices, and API responses with quantum-resistant signatures at sub-30ms latency. Verify signatures locally without exposing private keys.
Non-Exportable Key Management
Private keys are generated and stored exclusively within the KMS secure enclave. No API endpoint can export private key material. Keys are encrypted at rest with AES-256-GCM and referenced by handle, never by value.
Zero Trust Policy Engine
Every API request is evaluated against a dedicated policy engine with first-deny-wins rule chains. Plan-based restrictions, quota enforcement, and method-level access control. Fail-closed by default — if the engine is unavailable, all requests are denied.
API Key Management
Generate, rotate, and revoke API keys with zero downtime. Dual HMAC-SHA256 hashing for timing-safe authentication. Brief concurrent window during rotation ensures seamless key transitions without service interruption.
USE CASES
Built for Real-World Applications
Qpher uses Key Encapsulation Mechanism (KEM) — we generate a quantum-safe shared secret that you use to encrypt files locally. Your sensitive data never leaves your infrastructure, and the API payload stays small for sub-15ms latency.
Government & Defense
Defense secrets and diplomatic communications require protection for 25-50 years — well into the quantum computing era. Adversaries are already harvesting encrypted traffic today, waiting for quantum computers to decrypt it later (HNDL attacks). Qpher provides NIST FIPS 203/204 compliant algorithms to sign procurement contracts, encrypt classified documents, and maintain complete audit trails for government compliance. U.S. NSM-10 requires federal agencies to complete PQC migration by 2035.
Financial Services
Banking transaction records, customer KYC data, and credit card tokens need protection for decades. Qpher encrypts sensitive financial data using Kyber768 KEM — your files never leave your infrastructure. Call our API to get a quantum-safe shared secret, then encrypt locally with AES-256-GCM. Dilithium3 signatures secure contracts, transaction confirmations, and audit reports. Zero-trust policy engine and key rotation ensure ongoing compliance.
Healthcare
Protected Health Information (PHI) is a high-value target for attackers. HIPAA requires encryption of PHI at rest and in transit, and clinical trial data is typically retained for 15-25 years. Qpher encrypts sensitive EHR fields and signs prescriptions and lab reports to ensure integrity. Non-exportable keys and comprehensive audit logging satisfy HIPAA encryption requirements without changing your existing healthcare system architecture.
Legal & Compliance
Attorney-client privilege demands the highest level of confidentiality. Legal documents — contracts, litigation files, M&A due diligence — require long-term protection and verifiable signatures. Qpher's KEM enables quantum-safe encryption without uploading sensitive files to external servers. Dilithium3 signatures remain verifiable in the quantum era. Full audit trails serve as court-admissible evidence, and multi-tenant isolation ensures complete data separation.
SaaS & Technology
SaaS companies store vast amounts of customer data and need to stay ahead of security threats. 'Quantum-safe' is becoming a competitive differentiator that wins enterprise trust. Qpher's simple REST API and SDKs integrate in minutes — encrypt API secrets, user tokens, and tenant data with just a few lines of code. Sub-15ms latency means no impact on user experience. Focus on your core product while we handle PQC infrastructure.
Critical Infrastructure
Power grids, water utilities, transportation, and telecommunications have equipment lifecycles of 20-30 years. Attacks on these systems endanger public safety. Governments worldwide are mandating quantum-safe encryption for critical infrastructure. Qpher signs firmware updates with Dilithium3 to ensure integrity, encrypts SCADA commands and telemetry data, and provides strict access control through the policy engine. Version-controlled keys support long-term key lifecycle management.
