How to use

  1. 1 Pick an algorithm from the dropdown (SHA-256 by default).
  2. 2 Choose Text or File mode.
  3. 3 Type or paste text, or upload a file (up to 50 MB).
  4. 4 Choose Hex or Base64 output and copy the digest.

Why use this tool

  • 13 hash algorithms in one tool — pick from a dropdown instead of bookmarking five different pages.
  • Heavy libraries (js-sha3, spark-md5) are loaded only when their algorithm is first selected — fast initial paint.
  • File mode streams large files in 2 MB chunks where supported.
  • Pure client-side — text and files never leave your browser.

Frequently asked questions

Which algorithms are included?

MD4, MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-384, SHA3-512, Keccak-256 (the Ethereum variant), CRC-32, and NTLM.

Why are MD2, MD6, and Whirlpool missing?

MD2 has been deprecated since 1996 with no maintained JS implementation small enough to ship. MD6 is a research design with no real-world deployment. Whirlpool requires a 700-line table lookup — happy to add it on request if there is demand.

Is SHA-256 the right choice?

For most modern use cases yes — it is fast, well-supported, and considered secure. Use SHA3-256 or SHA-512 if you need post-MD/SHA-1 family separation. For password storage use a dedicated KDF like Argon2 or bcrypt, not a raw hash.

Need a single-algorithm tool?

Try our dedicated pages: MD5 Hash Generator, SHA-256 Hash Generator, SHA-1 Hash Generator, and Keccak-256 Hash Generator.

How is Keccak-256 different from SHA3-256?

Keccak-256 is the original Keccak submission with no padding tweak; SHA3-256 is NIST's standardised version with a slightly different padding byte. They produce different outputs for the same input. Ethereum uses Keccak-256 (Solidity keccak256()).

What is Hash Generator — All Algorithms?

A Hash Generator is a tool that computes cryptographic and checksum digests of text or files across many algorithms, including MD4, MD5, SHA-1, the SHA-2 family (SHA-224, SHA-256, SHA-384, SHA-512), SHA3, Keccak-256, CRC-32, and NTLM. It outputs the resulting digest for each selected algorithm. All hashing runs client-side in the browser, so input never leaves the device.

Features

Many algorithms at once

Compute MD5, SHA-1, SHA-256/512, SHA-3, Keccak-256, CRC-32, and NTLM together and compare digests.

Text or files

Hash typed text or drop in a file to fingerprint it byte-for-byte.

100% private

All hashing runs client-side — your input is never uploaded.

Example

Input

Zerethon

Output

MD5:     12b69cd48af1bae2634b3595f9c72f33
SHA-256: 37db5bf6cf84b6fc4d683553ab476292cb3b7c73202251f827bc2921ff3206cc

Common use cases

  1. 1

    Verify file integrity

    Compare a SHA-256 digest against a published checksum to confirm a download wasn't corrupted or tampered with.

  2. 2

    Fingerprint & deduplicate

    Use a hash as a stable key for caching or spotting duplicate content.

  3. 3

    Compare hash algorithms

    See how the same input maps across MD5, SHA-1, and SHA-256 for teaching or debugging.

Summary

Zerethon's hash generator computes many digest algorithms of text or files entirely in your browser — MD4, MD5, SHA-1, the SHA-2 family (SHA-224/256/384/512), SHA-3, Keccak-256, CRC-32, and NTLM. Each selected algorithm is shown side by side. Note that MD5, SHA-1, and MD4 are cryptographically broken — use SHA-256 or SHA-3 for security. Nothing is uploaded.
