QTCL

Encryption Stack

● Layer 1: PBKDF2-SHA256 (600K rounds) → AES-256-GCM (client-side, WebCrypto)

● Layer 2: Zero-knowledge storage (server stores opaque ciphertext — never decrypts)

● Layer 3: SHA3-256 chain anchor (immutable proof-of-existence on QTCL)

● Optional: Blinding nonce obfuscation (unlinkable on-chain hash)
