Confidentiality of private keys
Asymmetric encryption with the corresponding public/private
key pairs are used in the Microwall for the TLS protocol for
web accesses as well as for authentication within the WireGu-
ard VPN protocol. Both private keys of the Microwall cannot
be read out.
When setting up WireGuard VPN clients, there is an optional
option to have the key pair of the new client generated by the
Microwall for reasons of user-friendliness. Only choose this
method if you can guarantee a confidential transmission of
this key to the VPN client. For applications with increased pro-
tection requirements, we recommend generating the key pair
on the VPN client and then transmitting the uncritical public
key to the Microwall in another way.

ty requirements of the respective application, we recommend
taking appropriate precautions.
