Custom certificates could be embedded in the source code of Headwind MDM in PEM format. Note that it's unsafe to transfer certificates through the network due to a possible interception attack.
To embed certificates in the source code, please do the following:
1. Prepare the certificates in PEM (BASE64-encoded) format, and put them to assets subdirectory (one file per certificate).
2. Add the file names (without path, just file names, e.g. mycert.pem, myrootcert.pem) to res/values/strings.xml in the "certificates" string array.
The certificates will be installed at first app start (including the initial enrollment).
