About our Security Tools
Strengthen your security hygiene with tools that never see your secrets. Generate strong, customizable passwords and tokens, hash strings with MD5 and the SHA family, gauge password strength against modern guidelines and encode sensitive values. Because everything is computed in your browser using the Web Crypto API, your inputs are never transmitted anywhere.
Every tool in this collection is free, requires no sign-up, and processes your data entirely in your browser. That means there are no uploads, no waiting, and no privacy trade-offs — ideal whether you are on a fast desktop connection or a phone with patchy signal. Browse the 17 security tools above, or use the search to jump straight to the one you need.
