'RC' stands for 'Rivest Cipher'.<br><br><b>Key:</b> RC2 uses a variable size key.<br><br>You can generate a password-based key using one of the KDF operations.<br><br><b>IV:</b> To run the cipher in CBC mode, the Initialization Vector should be 8 bytes long. If the IV is left blank, the cipher will run in ECB mode.<br><br><b>Padding:</b> In both CBC and ECB mode, PKCS#7 padding will be used.";
