    Read the digests

    All six algorithms compute instantly.

  3. 03

    Toggle case

    Switch to uppercase hex if required.

  4. 04

    Copy

    Copy the digest you need with one click.

Use cases

Common use cases

  • Verify a downloaded file's checksum
  • Compare SHA-256 hashes for integrity
  • Generate cache or ETag keys
  • Create a fingerprint of a string
Overview

Every common hash, side by side

A hash function turns any input into a fixed-length fingerprint that changes completely if even one character changes. This tool computes six of the most-used algorithms at once — MD5, SHA-1, SHA-256, SHA-512, SHA-3 and RIPEMD-160 — so you can grab the exact digest a system expects. It's ideal for verifying file integrity, comparing checksums and generating cache keys.

Fast, local and private

Hashes update instantly as you type, and each one has its own copy button. Everything is computed in your browser with the crypto-js library, so your input is never uploaded. Note that MD5 and SHA-1 are fine for checksums but are no longer considered secure for passwords — use a dedicated password hashing function for that.

FAQ

Frequently asked questions

Which hash algorithms are supported?+

Six: MD5, SHA-1, SHA-256, SHA-512, SHA-3 and RIPEMD-160. All are computed simultaneously from your input.

Is my input sent anywhere?+

No. Hashing runs entirely in your browser using crypto-js, so your text is never uploaded or logged.

Can I use MD5 or SHA-1 for passwords?+

No — MD5 and SHA-1 are fast and outdated for password storage. They're fine for checksums and integrity, but use a dedicated password hash like bcrypt or Argon2 for passwords.

Why does one character change the whole hash?+

Good hash functions have an 'avalanche effect' — any tiny change to the input flips about half the output bits, so the digest looks completely different.
