Hash Generator (MD5, SHA-256)

How to use

1. Choose Text or File.
2. For Text, type or paste into the box; the hashes update as you type. The text is hashed as UTF-8.
3. For File, pick a file; its name and size in bytes are shown, and “Calculating…” appears while it is processed.
4. Read the MD5, SHA-1, SHA-256, SHA-384 and SHA-512 values in the table. They are shown in lowercase hex; tick Uppercase to show capital letters.
5. Copy a hash with the button next to it, or compare it with the value the publisher provides.

Frequently asked questions

Is my text or file uploaded?

No. Hashes are calculated in your browser; your text and files are not sent to our server or anywhere else.

Which hash should I use?

Use SHA-256 (or SHA-384/SHA-512) to verify downloads. MD5 and SHA-1 have practical collision attacks, so use them only to match old checksums, not to detect deliberate tampering.

Why is my hash different from another tool’s?

A hash depends on the exact bytes: an extra space or line break, or Windows (CRLF) versus Unix (LF) line endings, changes it completely. This tool hashes text as UTF-8, and line breaks typed in the box are LF.

Can I use this to hash passwords?

Not for storing them. A fast hash such as MD5 or SHA-256 can be guessed billions of times per second even with a salt; password storage needs a dedicated, deliberately slow algorithm such as Argon2, bcrypt or scrypt.

Is there a file size limit?

There is no fixed limit, but the whole file is loaded into memory, so files of several gigabytes may be slow or fail depending on your browser and device.
