PQCMail per Onion Search Engine

🔒 Post-Quantum Cryptography for Your Email
PQCMail brings quantum-resistant encryption to Gmail, Outlook, Yahoo Mail, and any webmail client — working the same way Mailvelope works for PGP, but with next-generation NIST-standardized algorithms.

⚛️ NIST Post-Quantum Algorithms
ML-KEM / CRYSTALS-Kyber (FIPS 203) — Key encapsulation for encryption
ML-DSA / CRYSTALS-Dilithium (FIPS 204) — Digital signatures
SLH-DSA / SPHINCS+ (FIPS 205) — Hash-based signatures
Hybrid X25519 + Kyber768 — Transitional mode (classical + PQC simultaneously)
🌐 Supported Webmail Clients
Gmail
Outlook Web
Yahoo Mail
OnionMail
Any textarea
🛡️ Privacy First
All cryptography runs 100% locally — no server-side crypto
Private keys never leave your device
Zero telemetry, zero analytics, zero ads
Open source — auditable by anyone
📦 Pure JavaScript — No WASM, No Native Code
Powered by @noble/post-quantum (MIT), a fully audited pure-JS implementation of NIST FIPS 203/204/205. No WebAssembly binary blobs, no CDN dependencies.
