Hash Generator

Compute SHA-1, SHA-256, and SHA-512 in the browser.

Sensitive processing stays in your browser whenever possible.

Details

Hash functions help with file integrity, output comparison, and teaching digest concepts. SHA-1 is not recommended for new security uses; prefer SHA-256 or stronger.

Computation is local so sample data does not leave your browser. Do not store passwords with a plain hash lacking proper salt/KDF.

Tips

For software-release integrity, publish the hash on a channel separate from the file.
A one-character change should yield a completely different digest—the avalanche property.
Hashing is one-way; do not expect to recover the original text from it.
