Password-protected files that anyone can open without special software is a genuinely clever idea. Solving the security vs. accessibility tradeoff for non-technical recipients is the right problem to tackle.

Open source encryption tool that works right in the browser - love the privacy-first approach! Being able to securely share secrets without any server dependency is a big deal for security-conscious users.

Does the hint go out with the message? Or is it for you to tell the person your password?

@alcazarsec

@clsmiles52 The hint is stored in HTML and displayed as a password hint to the recipient. Unlike the message, it is unencrypted and remains in plaintext to help the user recall or guess the password.
