About SHA-1 Hash Generator
The SHA-1 Hash Generator produces a 160-bit SHA-1 digest from text or a file. It remains common in legacy systems, Git object IDs, and older checksums, though it is no longer considered collision-resistant.
Plenty of existing systems still expect SHA-1. Generating it locally lets you match those systems while keeping your input on your own machine.
Step by step
- Enter text or drop a file into the tool.
- The SHA-1 digest is calculated in your browser.
- Copy the resulting hash.
- Repeat for any other input you need to fingerprint.
What it offers
- SHA-1 digest from text or files
- Instant computation — SHA-1 Hash
- Copyable hex result
- Hashing on your device
Tips for best results
- Avoid SHA-1 for new security designs; collisions are practical, so prefer SHA-256.
- SHA-1 is acceptable for non-security identifiers like content fingerprints.
- When verifying a download, match the exact algorithm the publisher listed.
