Using Certificates with the Debugger
When connecting remotely to Layout Developer via the socket, the information transmitted by default is not secure. The debugger now allows the use of HTTPS using installed certificates and key. The debugger supports the PEM format.
In order to use this, the debuggerCertificateChain property in the security.3ad file should point towards the certificate file and the debuggerPrivateKey keyword should point to the private key location.
Although the security.3ad file describes a way to create these items, PTC does not provide tools to do this. It might well be that your organisation already has their own versions of these files available to use. It is the user’s responsibility to create these and make them available to the debugger.
