About Encode & Crypto tools

Encoding is how data survives a trip through something that would otherwise mangle it — a URL, an HTTP header, an HTML page, a text-only transport. These tools do that translation in both directions, plus the one-way transformations (hashing) that verify data rather than move it.

Everything here runs on your own machine, which matters more in this category than any other: pasting a JWT, an API token or a password hash into a website that posts it to a backend means handing over the credential itself. Nothing you paste leaves the page.
