SHA-256 Hash Generator
Generate the SHA-256 hash of any text using the native Web Crypto API. 64-character hex hash, processed locally in your browser.
What is SHA-256 and what is it for?
Part of the SHA-2 family, SHA-256 (Secure Hash Algorithm 256) produces a 256-bit hash shown as 64 hexadecimal characters. No collision vulnerability has ever been found in it, which is why it's still treated as secure for cryptographic work.
You'll find it in SSL/TLS certificates, digital signatures, blockchain (Bitcoin being one example), file integrity checks and password storage with salt. In practice it took over from MD5 and SHA-1 across most modern systems.
Here the calculation runs right in your browser through the native Web Crypto API of modern browsers. Nothing travels over the network.
Generate the SHA-256 hash of a text
Modern and secure, SHA-256 belongs to the SHA-2 family and turns any text into a sequence of 64 hexadecimal characters. The calculation here uses the browser's native Web Crypto API, so you get the reliability of a standard implementation.
Unlike MD5, SHA-256 shows up in serious security contexts such as integrity verification, digital signatures, blockchains and identifier generation. When you need a robust, collision-resistant hash to check or identify content, it's the right choice.
The calculation happens entirely in the browser, with the text never sent anywhere. Paste the content and the SHA-256 hash shows up next.
