What These Developer Tools Do

Some developer jobs are small but easy to get wrong. These developer tools handle them in a few clicks. For instance, the Base64 tool, the string escape tool and the text to hex converter turn data into a safe form and back again.

Next, the security tools protect what matters. For example, the hash generator makes SHA and MD5 checksums, the bcrypt generator hashes passwords, and the AES tool encrypts a message with a key. The password and UUID generators make values that are hard to guess.

Because these developer tools run in your browser, keys and passwords never leave your computer. That is why they are safe for real work. In addition, every tool keeps working offline once the page has loaded.

Which developer tool should you use? To send binary data as text, use Base64. To check that a file arrived intact, use the hash generator. To store a password, use bcrypt, and to make a random ID that will not clash, use the UUID generator.

A word on safety. These developer tools run in your browser, so nothing you type is sent to us. Even so, change any secret that you pasted into a chat or a ticket. Treat the tools as a safe workbench, not as a reason to share keys.

All of the developer tools here follow the published standards. For example, Base64 uses the standard alphabet, the hashes match what command line tools produce, and the UUID generator makes versions 1 to 7. So the results work in any language or framework you use.

These tools also help when you read someone else's code. You can decode a token from a log to see what it holds, or compare a checksum from a release note with the file you downloaded. Small checks like these catch problems early.
