Encrypted Messages

An encrypted message on HandShake Factory is a blockchain contract where your content is:

• Military-grade encrypted — AES-256-GCM authenticated encryption, the same standard used for US TOP SECRET classified data
• Brute-force resistant — 125,000-iteration chained PBKDF2 key derivation makes password guessing computationally expensive
• Immutable — permanently preserved on the blockchain, impossible to alter or delete
• Access-controlled — only readable by those with the correct reference key
• Private by choice — your reference can be kept off-chain entirely for maximum privacy
