Hash (SHA)

Computes SHA-1, SHA-256, SHA-384 or SHA-512 of text.

Hash (SHA) computes the SHA-1, SHA-256, SHA-384, or SHA-512 digest of any text you paste in. It returns the hash as a lowercase hexadecimal string using the browser's built-in Web Crypto API, so it's handy whenever you need a quick checksum or digest while developing or debugging.

Common uses

• Generate a SHA-256 checksum to verify that a string or config value hasn't changed
• Compute a SHA-1 digest to compare against a value produced by another system
• Produce SHA-384 or SHA-512 hashes for stronger fingerprints of text content
• Create a deterministic hash key for caching or deduplicating identical strings
• Quickly check expected hash output while writing or testing hashing code

FAQ

Is my data sent to a server?

No. Hashing runs entirely in your browser using the Web Crypto API (crypto.subtle.digest). The text you enter is never uploaded or sent anywhere.

Which hash algorithms are supported?

SHA-1, SHA-256, SHA-384, and SHA-512. SHA-256 is the default; pick a different one from the Algorithm option.

What format is the output in?

The digest is returned as a lowercase hexadecimal string, with each byte represented by two hex characters.

Can I hash files or only text?

This tool hashes text input. The text is UTF-8 encoded before hashing, so identical text always produces the same digest.

Is MD5 supported?

No. The Web Crypto API only provides SHA-1, SHA-256, SHA-384, and SHA-512, so MD5 is not available here.
