The information and tools on DevTools Hub are provided for general use. This page sets out what that does and does not imply.
General information only
The guides on this site explain technical concepts in general terms. They are not professional advice, and they cannot account for the specifics of your situation. Where a decision carries real consequences, consult someone qualified to advise on it.
Security tools in particular
The hash generator, password generator, JWT decoder and related tools are provided for convenience and learning. Passwords generated here are produced with your browser's cryptographic random source, but we make no guarantee about the security of any particular result or how you subsequently store it.
Decoding a token here does not validate it for any security purpose, and verifying a signature confirms only what the cryptography states. Never rely on this site as the sole check in a security-critical process.
Accuracy
We test the logic behind each tool and correct errors when we find them, but we do not warrant that every result is accurate or current. If you spot something wrong, telling us is the fastest way to get it fixed.
External links and advertising
This site contains advertising and may link to external sites. We do not endorse, control or take responsibility for the content of advertisements or of sites we link to. Any dealings you have with an advertiser are between you and them.
