Generate SHA-1 and standard hash entries for Apache & Nginx HTTP Basic Authentication.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Input the desired authentication login username.
Type a strong password to be encrypted.
Copy the generated username:hash line and paste it into your server's .htpasswd file.
An .htpasswd file stores usernames and password hashes used by Apache and Nginx web servers to restrict access via HTTP Basic Authentication.
It should be placed outside the public document root (e.g. /home/user/.htpasswd) so it cannot be downloaded via a web browser.
Zero-egress companion tools in the Security & Network suite
