Security and Cryptographic Standards

Layer	Technology	Description
Key Exchange	ECDH (secp256k1)	Used for stealth address generation
Encryption	AES-GCM (256-bit)	Used by Lit Protocol for file encryption
Access Control	Wallet-based signature gating	Only authorized wallets can decrypt data
Hashing	Keccak256	Used for address derivation and file key mapping
Storage	Lighthouse / IPFS	Decentralized, immutable storage layer

All cryptographic functions are executed client-side, ensuring that no secret ever leaves the user’s browser.
