What these tools are for
This section collects small utilities that pair naturally with a temporary inbox: decoding a verification token during QA, formatting a webhook payload, generating a one-off test password, creating UUIDs for fixtures, hashing text for an integrity check, or safely encoding a callback parameter before pasting it into a test email.
The tools are deliberately simple. They do one job on the page, without accounts, dashboards, upload flows or background storage. That keeps the privacy model easy to understand: the browser receives the page assets, then your browser performs the operation locally.
Privacy model
Tool execution does not submit your input to EmailGenerator.pro. The JavaScript code runs in the current tab and writes the result back into the page. For hashing and random generation, it uses browser cryptography APIs. For formatting and encoding tools, it uses standard browser text APIs. You can confirm this in your browser's network panel by running a tool and watching that no tool-execution request is sent.
This does not mean every pasted value is risk-free. Browser extensions, shared computers, screen-recording software and clipboard history can still expose sensitive data. Treat active production tokens, private keys, customer records and unreleased credentials as secrets. When possible, inspect development or staging values instead.
How the tools connect to temporary email
Temporary email is often used while testing signup, login and transactional email flows. These tools help with the adjacent tasks: decode a JWT found in a magic-link flow, format JSON copied from a webhook debugger, URL-encode redirect parameters, generate random fixture strings, and create unique IDs while documenting a bug. For receiving the actual message, use the temporary email generator; for understanding the mail pipeline, read how temporary email works.
