Which hash should I use?

For security-sensitive work use SHA-256 or SHA-512. MD5 and SHA-1 are fine for quick checksums but are considered broken for security purposes.

Can I reverse a hash back to the text?

No. Hashing is one-way by design. This tool only generates hashes, it cannot decode them.

Hashes are computed in your browser. MD5 and SHA-1 are not secure for passwords or signatures; prefer SHA-256 or SHA-512 for security-sensitive use.

About the Hash Generator

A hash turns any text into a fixed-length fingerprint. The same input always produces the same hash, which makes hashes useful for checksums, cache keys and comparing data.

This tool generates MD5, SHA-1, the SHA-2 family (SHA-224, SHA-256, SHA-384, SHA-512) and SHA-3 (SHA3-256, SHA3-512) all at once, so you can grab whichever algorithm you need.

All hashing happens on your device, so the text you enter is never uploaded.
