Encrypt given data using rc2-128 cipher algo. RC2 with a 128-bit key size, providing stronger encryption compared to lower key lengths. RC2-128 was developed to offer better security than the base RC2 cipher, with a fixed key length for enhanced encryption strength. While more secure than lower key lengths of RC2, RC2-128 is still considered weak by modern standards and is no longer recommended for use. Our encryption process prepends the IV string used during the encryption process in the encrypted data so that it can be used during decryption.
