Local calculation
This page processes input and digests only in the current browser. It does not upload, query, or write input, expected values, or results to URL/storage.
Comparison meaning
A match means only that the selected local digest equals the expected value. It is not source trust, authenticity, or third-party evidence.
Report sharing
The report omits raw input and the raw expected value, but a digest can still identify a sample, text, or investigation target. Review authorization before sharing.
Passwords and scope
This page handles pasted text or encoded bytes. It is not a password storage tool; use a dedicated password hashing scheme for password storage.
A hash is an integrity digest, not encryption or password storage. SHA-1 is included for legacy compatibility only.
