Why compute multiple hashes at once?

A text hash generator applies several hash functions to the same input so you can see MD5, SHA-1, SHA-256, and related digests side by side. It saves the round trip of opening a separate tool per algorithm when you are verifying a download, comparing against a legacy checksum, or producing identifiers for several downstream consumers at once. All hashes are computed locally in the browser over UTF-8 bytes.

Use Cases

Match vendor-supplied checksums

Some vendors publish MD5 and SHA-256 together; compute both at once and pick whichever matches their documentation.

Migrate between hash algorithms

Run old and new algorithms simultaneously to confirm your migration script produces the right new digest for every record.

Build composite cache keys

When a key has to be short but collision-resistant, combine truncated hashes from different algorithms to reduce risk.

Verify fixtures in tests

Generate expected hashes of a canonical payload and paste them into test assertions instead of hard-coding by hand.

FAQ

Which algorithms are included?

Typical fast digests: MD5, SHA-1, SHA-256, and SHA-512. Longer or niche algorithms are deferred to their dedicated tools.

Are hashes computed in the browser?

Yes. The browser crypto API handles SHA variants; MD5 runs through a small JS implementation so no input leaves the tab.

How is input encoded before hashing?

Input is serialized as UTF-8 bytes before hashing, which matches the default behavior of most language runtimes.

Can I hash binary data?

The tool focuses on text. For arbitrary bytes, Base64-encode the input first or use a dedicated file hashing utility.
