Troubleshoot: Polycom endeavors to maintain a built-in list of the most commonly used Certificate
Authority (CA) certificates. Due to memory constraints, we cannot ensure a complete set of
certificates.
If you are using a certificate from a commercial CA not in the list above, you can submit a feature
request for Polycom to add your CA to the trusted list. At this point, you can use the custom certificate
method to load your particular CA certificate into the system. See

Encrypt Configuration Files

The system can recognize encrypted files. Systems can download encrypted files from the provisioning
server and can encrypt files before uploading them to the provisioning server. There must be an encryption
key on the system to perform these operations. You can encrypt configuration files (excluding the master
configuration file), contact directories, and configuration override files.
You can generate your own 32 hex-digit, 128 bit key to encrypt and decrypt configuration files on a UNIX or
Linux server.
The SDK generates a random key and applies Advanced Encryption Standard (AES) 128 in Cipher Block
Chaining (CBC) mode. For example, a key can look like this:
Crypt=1;KeyDesc=companyNameKey1;Key=06a9214036b8a15b512e03d53412006;
