Certificates for the secure data transfer

The "Transport Layer Security" (TLS) protocol enables encrypted data transfer between a client
and the SINAMICS drive. TLS is the basis for https access of the browser to the drive.
"Transport Layer Security" (TLS), more widely known under the predecessor designation
"Secure Sockets Layer" (SSL), is a hybrid encryption protocol for secure transfer of data in the
Internet.
The encrypted variant of communication between the browser and the Web server using
HTTPS requires the creation and installation of certificates (default configuration, self-created
certificates or server certificates from a certification authority).
Protecting the HTTPS access
To enable encrypted communication between the browser and the web server via HTTPS, you
must install certificates. You have three options:
● Use the standard configuration
● Use certificates created with certificate software such as OpenSSL
● Use a server certificate from a certificate authority
Key files
For the encryption process you will need 2 key files:
● A public certificate (Public Certificate)
● A private key (Private Key)
