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()).
