Certificate authority (CA) files for the service to authenticate server certificates.
|
Value |
String. The path and filename of a CA certificate. If you have certificates from more than one CA, specify a comma-separated list (one file per CA). For the recommended path, see Copying certificates and keys. |
|
Default |
(empty) |
|
How to set |
Set on the Nuance Text Processing Engine service in Management Station. If not using Management Station, set in the NTpE service configuration file (User-ntpexx.yaml, see Configuration roadmap). In Management Station, format the value as a string array: one or more comma-separated values enclosed in square brackets [ ]. |
|
Usage |
Typically changed once, when setting up secure connections during the transition from development to production environments. See Securing connections with SSL/TLS. Valid when httpsClient : requestCert is enabled. |
Specifies the certification authority file (or files) for validating the certificates of an HTTPS resource. When a Dragon Voice service acts as a client (by sending an https GET or POST to a server), the server responds by sending its certificate to the client. (For example, a service is a client when it registers with the Resource Manager service.) The client service receives the server's certificate and authenticates it using a CA certificate specified by this property. (The client only authenticates when you've enabled its rejectUnauthorized property.)
Specifies the certification authority file (or files) for validating the certificates of an HTTPS resource. The httpClient properties control how the service behaves when acting as a client. For example, when NTpE downloads directly resources such as application linguistic models from the Natural Language Engine.
Most sites do not need to specify this property. By default (the property is empty), the service loads any trusted CA signing certificates already loaded on the host. This means that if you acquire Speech Suite certificates from an authority that is already loaded, it's not necessary to configure this property. (There's no problem if you specify the property unnecessarily, in which case you overwrite the default behavior.) If you acquire certificates from more than one authority, include every CA file.
