The hardware key (dongle) used with Ple4Win has a cryptographic processor inside, which is controlled using a bit of internal programming (the firmware). As with normal software, firmware can be changed and re-programmed into the key. Firmware changes can only be done by Wibu Systems, but updating the firmware of a key can be done by a user.

Info To use Ple4Win, a minimum firmware version of 1.18 is required. However, to ensure compatibility with future developments, it is recommended to use firmware version 4.01 or higher.
