Hash digest calculator

Calculate SHA-1, SHA-256, SHA-384, and SHA-512 digests locally with browser Web Crypto from UTF-8, Hex, Base64, or Base64URL byte input, then optionally compare an expected Hex, Base64, or Base64URL value. Input and output are not uploaded, written to the URL, stored, or sent to backend logs.

A hash is an integrity digest, not encryption or password storage. SHA-1 is included for legacy compatibility only.

Input limit 1 MiB. Browser Web Crypto calculates locally; choose an input format, paste content, then calculate a digest.

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.

Recommended from common tool workflows. This section does not read or pass page input.
