SHA-256 Generator

FAQ

Does this page load MD5 code?+

No. This route uses Web Crypto only. spark-md5 is reserved for the MD5 generator and when MD5 is selected on the hash generator.

What is SHA-256 used for?+

SHA-256 is common for checksums, Git commit IDs, blockchain references, and API signatures where SHA-512 is not required.

What encoding is hashed?+

UTF-8 bytes of your text, matching typical server-side implementations for Unicode strings.

Is processing local?+

Yes. digest() runs in your browser via crypto.subtle. Your input is not transmitted.

Can I verify a Git commit or checksum?+

Paste the exact string being hashed — Git commit IDs hash a specific header format, not arbitrary text. For file checksums, hash the file bytes in a file-hash workflow when available.
