Why this tool exists
Hash Generator creates deterministic digests for text values directly in the browser.
It is useful for data integrity checks, debugging signatures, and reproducible fingerprints of payloads.
Common use cases
- Generate SHA-256 checksums for config strings and payload snapshots.
- Compare whether two text blobs are identical without visual diffing.
- Produce reference digests for API docs and test fixtures.

Common errors
Unexpected hash mismatch
Cause: Whitespace or newline differences changed the input string bytes.
Fix: Normalize input text (trim or keep exact whitespace) before generating hashes.

Frequently asked questions
Which algorithms are supported?
The tool supports SHA-256 and SHA-1 in-browser, plus MD5 compatibility reference guidance.
Is hashing reversible?
No. Hashing is one-way and cannot be directly reversed to recover the original text.
