With DESkey you have a choice of integrating our API calls into your software to make whatever secure system you want.


DESnet provides a system for multi-user access to a DK2 DESkey across a network, LAN or WAN. The server DESkey may be attached to any PC on the network, including file servers and workstations. DESnet supports TCP/IP and can be adjusted to suit any firewall restrictions you may have. The DK2 can be remotely updated using the built-in secure encrypted instruction transfer protocol in almost any medium from email to phone to fax.
