AES-256-GCM
Authenticated encryption with a 256-bit key. If a single byte of the message is altered, decryption fails loudly instead of returning garbage.
Lock text, rich formatting and images behind a password using AES-256. All encryption happens locally on your device — there is no account, no upload, and nothing for anyone to leak.
Tip: there is no way to recover a lost password — store it safely.
Authenticated encryption with a 256-bit key. If a single byte of the message is altered, decryption fails loudly instead of returning garbage.
Your password is stretched into a key with PBKDF2 (250,000 SHA-256 rounds) over a random salt — slowing brute-force attempts.
All cryptography runs in your browser via the audited Web Crypto API. No servers, no logging, no analytics. Works offline.
Encrypted blocks are plain text you can paste into email, chat or docs. The same engine will power the upcoming Firefox & Chrome extensions.
