SiPass Entro uses integral encryption software when communicating in network
environments. This higher security level is necessary - especially when SiPass
Entro is installed in Internet applications.
The user of SiPass Entro should regularly change the crypto key needed by the
encryption algorithm. The crypto key will always be stored in the database. The
algorithm uses 128-bit level.
If the crypto key is not correct the communication is not established – and the
system must be completely reset and re-configured.
Because of the fact that network use needs an encryption algorithm the security
aspects of a system are improved. At the same time this raises some important
points:
Always write down the crypto key as soon as it is changed from the standard!

There are no back-doors into the system. I e there is no work-around if the

crypto key is lost.
The only way to re-create a system - is to reset it and re-configure the entire

information.
A good idea is to use the default crypto key (used at delivery) until the system is
completely set-up – and then change it.
