What is hash generator?

Hashes are one-way fingerprints of data. Compare two hashes to verify that a file was not tampered with, store passwords securely, or check an integrity checksum after a download.

This tool computes MD5, SHA-1, SHA-256, and SHA-512 digests of any text you type — or any file you drop in. Every hash updates live as you type.

How to use it

  1. Type or paste text

    All four digests update live as you type.

  2. Hash a file instead

    Drop a file anywhere on the page to compute its checksum — useful for verifying downloads.

  3. Copy any digest

    Each hash has its own copy button.

Examples

The classic "abc" vector

Well-known reference digests.

abc

Result: MD5 900150983cd24fb0d6963f7d28e17f72 · SHA-256 ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad
