CertL4cates
1469-089
In order to encrypt communication with a remote device, an encryption key must be sent and received over an unsecured network beforehand. This problem is solved by public-key cryptography. Public-key cryptography ensuressecure communication by protecting important and valuable information from attacks, such as  sniwng, spoo4ng,  and
tampering of data as it  5ows over a network.

GeneratingKeyPairs
1469-08A
A key pair can be generated with the machine when it is required for encrypted communication via Transport Layer
Security (TLS). You can use TLS when accessing the machine via the Remote UI. Up to  4ve key pairs (including the
preinstalled pairs) can be generated to the machine. Self-signed  certi4cates are used with key pairs generated in
"Network Communication". With a "Key and  Certi4cate Signing Request (CSR)", you can apply for a CA-issued digital...
