What is in Generators
Tools that produce something from nothing: barcodes in CODE128, EAN-13, UPC-A, ITF and CODE39, Diceware style passphrases, cryptographically secure random strings and tokens, and usernames.
The random values come from the browser's own crypto source rather than from an ordinary pseudo random number generator, which is the difference between a token that is genuinely unguessable and one that merely looks it. Nothing generated here is logged or reused.
Diceware passphrases are worth a look if you still write passwords by hand. Four or five common words chosen at random are both easier to remember and harder to guess than the usual substituted characters.
The barcodes cover the symbologies that come up in practice: CODE128 for general purpose labels, EAN-13 and UPC-A for retail products, ITF for cartons and CODE39 for older industrial scanners. They download as SVG so they stay sharp at any print size, and as PNG for software that will not take vector input.
Common questions
Are the random values actually secure?
+
They come from the Web Crypto getRandomValues source, which is the browser's cryptographically secure generator. They are suitable for tokens, salts and passwords, and they are never sent anywhere or stored.
How long should a Diceware passphrase be?
+
Four words gives roughly 52 bits of entropy and five gives about 65, assuming the words are chosen at random from a large list. Five words is a reasonable default for anything that matters, and it is still easier to type than a substituted password.
Can I print the barcodes?
+
Yes. They download as SVG, which scales to any size without softening, and as PNG for tools that will not take vector input. Check the printed result with a scanner before committing to a large run.
