Hash

One tool, five hashes at once

A hash is a one-way function that turns any text into a fixed-length fingerprint. It is used for file integrity checks, checksum comparisons, and debugging API signatures. Type your input and the MD5 and SHA hashes are computed live — entirely in your browser, so nothing is ever sent anywhere.

Five algorithms at once

Compare MD5, SHA-1, SHA-256, SHA-384, and SHA-512 side by side on one screen.

Live compute, one-click copy

Hashes update as you type, and each result copies with a single click.

Fully in-browser

Your text never leaves the browser, so even sensitive values stay private.

FAQ

Frequently asked questions

Is MD5 secure?

MD5 is vulnerable to collision attacks and is not recommended for security or password storage. It is still handy for non-security uses like checksums or cache keys. For security, use SHA-256 or stronger.

Can I reverse a hash back to the text?

No. Hashing is one-way, so the original input cannot be recovered from the result. The same input simply always produces the same hash.

Are Korean text and emoji hashed correctly?

Yes. Input is UTF-8 encoded before hashing, so Korean text, emoji, and special characters match standard tools.

What if I need uppercase hashes?

Turn on the uppercase toggle to show every result as uppercase hex. The hash value itself is unchanged.
