Hash Generator SHA-1

Generate SHA-1 hashes from text or files

Input

What is Hash Generator SHA-1?

A SHA-1 hash generator produces a 160-bit (40-character hex) digest of any input. SHA-1 is used in Git commit hashes, legacy certificate fingerprints, and data integrity verification where collision resistance isn't critical.

How to use

  1. Step 1 — Type or paste text, or drop a file to compute its SHA-1 digest.
  2. Step 2 — The hash is generated entirely in your browser — nothing is uploaded.
  3. Step 3 — Copy the 40-character hex string or verify it against an expected value.

Result

You need to verify a Git object's SHA-1 hash matches what's displayed in your repository log. Paste the object content here and compare the output.
