Developer Utility Suite

Cryptographically secure passwords, UUID v4 generator, Base64 encoder, and SHA-256 hashes.

What this tool does

Four everyday developer helpers in one place: a password generator built on the browser secure random source, a UUID v4 generator, a Base64 encoder and decoder, and a SHA-256 hash calculator. Everything runs locally so sensitive strings never reach a server.

How to use it

  1. Choose the utility you need.
  2. Enter your input or set the options.
  3. Copy the generated result.

Frequently asked questions

Are generated passwords stored?

No. They are created in your browser and disappear when you close the tab.

Is Base64 a form of encryption?

No. It only changes the representation of data and offers no protection.
