You can configure the passphrases that a listener requires in the mf-server.dat file. When you start the listener, it retrieves the passphrases from the file, and you do not need to configure them manually.
If you are securing the Communications Process use the name of the enterprise server region as the listener name.
By default, the mf-server.dat file is in the %ProgramFiles(x86)%\Micro Focus\Enterprise Developer\bin directory:
[Listener-name/SSL/passphrases] certificate=certificate passphrase keyfile=keyfile passphrasewhere:
mfsecret:configuration-name:secret-path
or:
mfsecret::secret-path
or:
mfsecret:secret-path
