SHA-1 Integrity Receipt

01 / Tool workbench

Use the runtime only when it is actually ready.

The application shell fails closed. An input interface is not enabled merely because a WordPress Tool record exists; the declared engine must be registered in the current build.

SHA-1 Integrity Receipt

BROWSER LOCAL

Checking whether the declared runtime module is loaded. No input has been processed.

Session change summary

No output has been built in this session.

What this Tool does

Calculate SHA-1 over the exact bytes of one local file, optionally compare an expected digest, and export a deterministic read-only integrity receipt without inferring file validity.

Coverage is explicit

The digest covers the exact selected file from byte 0 through end-of-file. An expected digest is optional and must have the exact width for the fixed algorithm.

What the result means

A digest match is not proof of authenticity, semantic validity, game compatibility or safe editability. Phase 73 never repairs or rewrites a save and never guesses checksum coverage or byte order.

Safe workflow

Keep the source backed up, use only a checksum rule documented for the exact format, and preserve the generated receipt alongside the file you analyzed. The source file is never modified in place.

02 / Compatibility

Know the supported input before opening a file.

Compatibility fields are intentionally explicit. Missing values stay unclaimed rather than being filled with generic assumptions.

Accepted extensions

No extension list is recorded.

Platforms

No platform assignment is recorded.

Supported versions / editions

Any local binary file up to the permanent 16 MiB browser-local ceiling. The checksum/hash algorithm itself is the already-verified Phase 17 implementation named by this Tool.

Input constraints

The digest covers the exact selected file from byte 0 through end-of-file. An expected digest is optional and must have the exact width for the fixed algorithm.

Known limitations

A digest match is not proof of authenticity, semantic validity, game compatibility or safe editability. Phase 73 never repairs or rewrites a save and never guesses checksum coverage or byte order.

Output / result

A deterministic JSON integrity receipt containing source SHA-256, the explicit coverage rule, the computed digest, and an optional exact expected-digest comparison. No modified save file is emitted.

03 / Instructions

Use an explicit conversion workflow.

General utilities operate only on the value and options you provide. No game format is inferred behind the scenes.

01Choose the format
Confirm the expected base, encoding, width, precision, or time unit before conversion.
02Enter the value
Use only the syntax documented in the compatibility and input sections.
03Convert locally
Run the verified browser engine and review any validation message instead of forcing rejected input.
04Verify the result
Check the output format before copying it into another file, tool, or workflow.

Tool-specific steps

Choose the local file, optionally paste the expected hexadecimal digest, then calculate and save the JSON receipt. Interpret a match only within the named algorithm contract.

04 / Privacy and processing

The processing mode is part of the product contract.

SaveEditor.com should state local processing only when the implementation truly keeps file contents in the browser. Server or hybrid processing must be disclosed just as clearly.

Declared mode

Browser local

Runtime state

Operational

Tool-specific privacy notes

The selected file is read locally in browser memory. Phase 73 performs no fetch, XMLHttpRequest, WebSocket, sendBeacon, account login, cloud synchronization, remote hashing, or remote validation.

05 / Troubleshooting

Rejected input is a validation signal.

The converter fails closed on invalid digits, malformed byte sequences, ambiguous date input, unsupported widths, and values beyond documented bounds.

Wrong syntax

Confirm the selected base, encoding, byte grouping, or numeric form matches the documented input contract.

Out of bounds

Reduce the input size or choose a supported bit width instead of relying on implicit truncation.

Ambiguous interpretation

Specify the intended width, precision, or timezone explicitly when those details change the result.

Known Tool issues

A mismatch means only that the computed digest under the exact selected rule differs from the expected digest. Confirm algorithm variant, exact byte range, zero/exclusion rule and expected value before drawing conclusions about corruption.

06 / Verification

Support claims should be traceable.

The verification date, method notes, and public references are kept separate from marketing language so compatibility can be reviewed over time.

Method notes

Verified against the existing Phase 17 hash-core vector authority plus Phase 73 whole-file/range/zero/exclusion fixtures, source immutability checks, malformed-range negatives, independent reference calculations and source/installable parity.

07 / FAQ

Questions to answer before editing.

These answers are generated from the Tool record and current runtime state rather than generic compatibility promises.

Is SHA-1 Integrity Receipt ready to use?

The Tool record is verified and declares an operational runtime. The page enables its input controls only when the declared engine module is loaded in the current build.

Does processing stay in the browser?

Yes for this declared mode. The loaded runtime processes the explicit input in the browser; Tool-specific privacy notes describe the exact scope and limits.

Does this utility change my source value?

No source data is modified by the converter. It calculates a result from the value and options you explicitly provide.

What if my input is rejected?

Use the validation message to correct the base, encoding, width, timezone, byte alignment, or size. The runtime does not guess through invalid input.
