How to use

Using RC2 Decrypt 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 RC2 Decrypt?

RC2 Decrypt rC2 (also known as ARC2) is a symmetric-key block cipher designed by Ron Rivest in 1987. 'RC' stands for 'Rivest Cipher'. Key: RC2 uses a variable size key. IV: To run the cipher in CBC mode, the Initialization Vector should be 8 bytes long. It runs entirely in your browser, so your data stays private.

Is RC2 Decrypt free to use?

Yes. RC2 Decrypt 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.
