Not gated. Your PII is never captured. No cookies.
Public — opens right here for anyone. No key needed.
Decrypted
Every byte is sealed and opened right here in your browser. No server ever sees your message — or your key.
scrypt (N=16384, r=8, p=1) hardens your key; AES-256-GCM seals the message with authenticated encryption.
No public-key crypto for Shor’s algorithm to break. Grover’s search still leaves AES-256 at 2128 effective strength — beyond any machine, quantum or otherwise.
A wrong key or a tampered message fails whole — authenticated encryption gives no partial reveal.
Two tiers — Public opens for anyone, no key; Sealed locks under a word that lives only in your head.
Not gated · no PII captured · no cookies · nothing is ever sent anywhere.
This tool and any message it reveals are for your private use only.
