DEVELOPER BENCH
Hash supplied UTF-8 text with SHA-1, SHA-256, or SHA-512 using the browser Web Crypto API.
WHAT THIS DOES
Runs entirely in your browser.

BATCH / ONE VALUE PER LINE
Up to 200 lines, one at a time, in this browser. Each line takes the place of text and everything else stays as you set it. Nothing is uploaded, and the row limit is not exceeded silently.
METHOD / LOCAL RUN
The selected Web Crypto SHA algorithm hashes UTF-8 text locally and returns lowercase hexadecimal bytes.
Boundary: A text digest is not file-integrity verification, password storage, signature verification, secret management, or an authentication decision.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ
A text digest is not file-integrity verification, password storage, signature verification, secret management, or an authentication decision.
No. This published tool runs locally in your browser. UtilityForge does not send the values entered in this workbench to a server.
No. This workbench runs in the page: Text to hash, Hash algorithm are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
Yes, and it is enforced rather than advertised: Text to hash (100,000 characters). The limit is a browser input limit on a tool that runs on this device, so nothing is truncated after being sent anywhere.
