Contact Us
You can send feedback, bug reports, or feature requests for Crypto & Hash Tools through the contact form on this page. The form opens a prefilled email message addressed to the project team. We do not collect form submissions on a server — the message is composed in your email client.
What You Can Contact Us About
We welcome input that helps improve the tools. The most useful messages tell us what happened, which tool it involved, and what you expected. Common topics are listed below.
Bug Reports
If a tool behaves unexpectedly — for example, a button that does not respond or output that does not update — tell us the tool name, the steps you took, your browser, and what you saw. A screenshot or the exact input helps us reproduce the issue.
Incorrect Results
If a hash, HMAC, checksum, UUID, or regex result does not match a known reference value, please report it. Include the tool, the input (or a non-sensitive equivalent), the output you received, and the expected output from an independent source so we can investigate.
Feature Requests
Suggestions for new tools, additional algorithms, or improvements to existing ones are welcome. Describe the use case you are trying to solve; that helps us judge whether a feature fits the project's scope.
Security Concerns
If you believe you have found a security issue, please describe it responsibly. Do not paste real secrets, API keys, or tokens into the message. For sensitive details, describe the concern in general terms and we will follow up on how to share specifics safely.
General Questions
Questions about how a tool works, which algorithm to choose, or the privacy model are welcome. For broader answers, the FAQ and About pages may already cover your question.
Expected Response
This is a small, volunteer-maintained project, so we cannot guarantee a response time or a reply to every message. We read all feedback and use it to prioritize fixes and improvements. Please avoid including sensitive information, as email is not a secure channel.
Direct Email
You can also email us directly at support.freeutilityhub@gmail.com. The contact form simply pre-fills a message to that address using your email client.
