Hash Compare

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.

Hash Compare

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 utility does

Calculate a selected checksum or hash locally and compare it with an expected hexadecimal digest without uploading the input.

Algorithm and input contract

Supports CRC-32, Adler-32, MD5, SHA-1, SHA-256, and SHA-512 in the comparison interface. The expected digest must have the exact hexadecimal length for the selected algorithm. The calculated digest plus an explicit Match or No match verdict.

Important limitations

A matching digest means the calculated bytes match the expected digest under that algorithm. It is not a malware scan, signature verification, or independent proof of source authenticity.

SaveEditor.com performs this Phase 17 calculation locally in the browser. The result is derived from the exact bytes supplied by the selected input source; the utility does not infer a game format or silently normalize file contents.

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

Modern evergreen browsers with JavaScript enabled. SHA-1, SHA-256, and SHA-512 use the browser Web Crypto API. CRC, Adler-32, and MD5 use deterministic local JavaScript implementations.

Input constraints

Supports CRC-32, Adler-32, MD5, SHA-1, SHA-256, and SHA-512 in the comparison interface. The expected digest must have the exact hexadecimal length for the selected algorithm.

Known limitations

A matching digest means the calculated bytes match the expected digest under that algorithm. It is not a malware scan, signature verification, or independent proof of source authenticity.

Output / result

The calculated digest plus an explicit Match or No match verdict.

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

Select the algorithm, paste the expected digest, choose the input source, and select Compare hash.

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 Phase 17 runtime performs no network requests. Text and pasted hex are processed locally. A local file is read only after the user selects it; files are buffered in browser memory and limited to 16 MiB. Pasted hex is limited to 2 MiB of decoded bytes and text input to 1,048,576 characters / 4 MiB UTF-8.

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

If comparison fails before calculation, verify the expected digest length and remove labels such as sha256= before pasting.

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 deterministic Phase 17 checksum/hash vector suite in tests/phase17-hash-core.test.js and docs/qa/phase17-hash-vectors.json. Vectors include the standard ASCII string 123456789 for CRC variants, Adler-32, MD5, SHA-1, SHA-256, and SHA-512, plus empty-input and digest-comparison tests.

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 Hash Compare 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.
