DEVELOPER BENCH
Create a hexadecimal SHA-256 digest with the browser Web Crypto API. This text hash utility is not a substitute for a file-integrity or secret-management workflow.
WHAT THIS DOES
Runs entirely in your browser.
/tools/sha256-checksumsha256v2.0.0LOCAL · LOCAL RUNIMPLEMENTED — This workbench is functional in the current release.Presets for this workbench
No preset yet. A preset stores the values in this form — never the result — and only for workbenches that run entirely in your browser.
Collections
Saved on this device only. Turn on sync to carry them to another device.
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 browser Web Crypto API hashes UTF-8 encoded input with SHA-256 and returns a hexadecimal digest.
Boundary: This hashes supplied text only. It does not verify files, signatures, provenance, password strength, or the safety of a source.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ
No. This published tool runs locally in your browser. UtilityForge does not send the values entered in this workbench to a server.
The workbench states the exact method behind every result — the formula or procedure this page runs — so you can verify the computation instead of trusting a black box.
No. This workbench runs in the page: Text to hash 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.
This hashes supplied text only. It does not verify files, signatures, provenance, password strength, or the safety of a source.
