How is SHA-256 computed?

In your browser via the Web Crypto API (crypto.subtle.digest). Nothing is sent to a server.

Need other algorithms too?

Open the Hash Generator for MD5, SHA-1, SHA-384, and SHA-512 alongside SHA-256.

What is an HTML color code?

An HTML color code is a way to specify colors in web pages using HEX (#RRGGBB), RGB, HSL, or named CSS colors. HEX is the most common format in CSS and HTML.
