You are obtaining identity certificates and encryption keys from a Certificate Authority (CA) for installation...

When installing the identity certificate and encryption key files on the Avaya Session Border Controller for Enterprise (ASBCE), you need to follow this rule: The filename of the identity certificate (.pem or .crt file) must be different from the filename of the encryption key (.key file). An identity certificate is a file that contains information about the identity and public key of an entity, such as a server or an endpoint. An encryption key is a file that contains information about the private key of an entity, which is used to encrypt and decrypt data. The identity certificate and encryption key files are obtained from a Certificate Authority (CA) or generated by yourself using tools such as OpenSSL. When installing these files on the ASBCE server, you need to make sure that they have different filenames, otherwise they will overwriteeach other and cause errors. For example, you can name them as sbce-cert.pem and sbce-key.key respectively.
