Privacy & Security
Small tools that make you meaningfully harder to hack. Generate passwords with real cryptographic randomness, check how long a password would survive a brute-force attack, and learn what actually matters about account security. Nothing is transmitted or logged.
A small set of tools for the security and privacy tasks that come up in ordinary life, all of which run entirely in your browser. That last point is not a marketing line here, it is the whole design: a password generator that sends candidate passwords to a server is not a password generator, it is a liability.
"For passwords, the generator uses the browser's cryptographic random source rather than the ordinary random function, and the strength checker estimates how long a password would survive an offline attack. The important finding from using it is usually that length beats complexity by a wide margin: a long passphrase of ordinary words outlasts a short string of substituted symbols, which is the opposite of what most password rules push people towards."
For files and text, the encryption tool uses the Web Crypto API to encrypt with a passphrase locally, and the hash generator computes MD5, SHA-1, SHA-256 and SHA-512 digests for verifying that a download matches what was published. Neither the input nor the output leaves the page.
For privacy, the browser privacy check shows what any website can read about you without permission: your screen, timezone, fonts, hardware details and the combination of them that makes up a fingerprint. It is not an audit and it does not fix anything. It is a demonstration of how identifiable a browser is by default, which is worth seeing once.
Everything here is deliberately narrow. These tools do the specific job and stop, and none of them requires an account, an email address or trust in anything beyond the code running in your own tab.
