Hash Generator
Hash text or files and check them against a published checksum.
Password Generator
Create strong random passwords with your choice of length and symbols.
About these tools
A password generated by a website that then transmits it is not a secure password, whatever the site says about its logging. Both tools here run in your browser: the Password Generator draws its randomness from crypto.getRandomValues(), and the Hash Generator computes digests locally, so the output exists only in your tab.
That distinction matters more than it sounds. Cryptographically secure randomness is what makes a generated password unpredictable, and it is not what Math.random() provides, despite how many generators rely on it.
The most common everyday use of a hash is checking a download. Software projects publish the SHA-256 of each release; hash the file you received, paste the published value into the Hash Generator's expected-hash box, and it tells you whether they match. A mismatch means the file is corrupted or is not the one the project published. Large files are read in chunks, so this works on multi-gigabyte ISOs without loading them into memory at once.
