FAQ

What is RC2 Encrypt?

RC2 Encrypt 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. You can generate a password-based key using one of the KDF operations. IV: To run t. It runs entirely in your browser, so your data stays private.

Is RC2 Encrypt free to use?

Yes. RC2 Encrypt 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.
