How to use: MD2

MD2 is a free online Cryptography Tools tool that the MD2 (Message-Digest 2) algorithm is a cryptographic hash function developed by Ronald Rivest in 1989. The algorithm is optimized for 8-bit computers. Although MD2 is no longer considered secure, even as of 2014, it remains in use in pub instantly in your browser. Paste your data, adjust the options and get the result in real time — no installation, no sign-up, and nothing is ever uploaded to a server.

How to use

Using MD2 takes three steps:

  1. Paste your data into the input box (or load the example).
  2. Configure the options to match your target format or scenario.
  3. Copy, download or inspect the output — it updates live as you type.

FAQ

What is MD2?

MD2 the MD2 (Message-Digest 2) algorithm is a cryptographic hash function developed by Ronald Rivest in 1989. The algorithm is optimized for 8-bit computers. Although MD2 is no longer considered secure, even as of 2014, it remains in use in pub. It runs entirely in your browser, so your data stays private.

Is MD2 free to use?

Yes. MD2 is free, unlimited and works without registration or installation.

Does my data get uploaded?

No. All processing happens locally in your browser; nothing is sent to any server.

Good to know

  • Everything runs client-side, so extremely large inputs are limited by your browser tab’s memory rather than by a server upload limit.
  • The worked example below could not be pre-computed for this tool (threw: function is not iterable (cannot read property Symbol(Symbol.iterator))); the interactive tool above still works normally.
