About EncryptWatch

EncryptWatch provides free, easy-to-use online tools for security and web development. Our goal is simple: build genuinely useful utilities, explain clearly how each one works, and keep your data private.

What we offer

Our tools help you generate strong passwords, encode and decode data, hash files, validate JSON, inspect JSON Web Tokens, and more. New tools are added regularly across categories including passwords, encoding, hashing, DNS, TLS, email authentication, and developer utilities.

Privacy first

Most of our tools are marked “Runs in browser.” That means the processing happens entirely on your own device using JavaScript. When you generate a password or hash a file with one of these tools, the data is never transmitted to us or any third party.

How we keep the tools free

EncryptWatch is supported by advertising. Ads appear on explanatory pages and are kept separate from the areas where you enter sensitive data. This lets us offer every tool at no cost.

Accuracy & limitations

We work hard to make our tools correct and our explanations accurate, but no online tool can guarantee security. A passing result is a helpful signal, not a certification. Always combine these utilities with professional judgment and, where appropriate, expert review.
