Initializing help system before first use

https_cacerts

Description
Location of the file containing the certificates of the trusted certification authorities.
Type
String, read/write
Note
The file identified by this parameter consists of a list of certificates (in PEM format) of trusted certification authorities (in order to be able to check the validity of servers they have certified) and certificates of servers trusted by the application (typically using self-signed certificates that could not be certified by an external authority, see x509newcrt). This file is used when HTTPS client connections are established to check the identity of the server unless the control parameter https_trustsrv is set to true. It is also required by servers that perform client authentication (see option HTTP_CLTAUTH of server configuration http_srvconfig): in this case the certificates are used to identify the clients.
When this parameter has not been initialised, the default location getparam("ssl_dir")+"/ca-bundle.crt" is used. This default file collecting the certificates of the major certification authorities is installed by the mmssl setup command (Section The mmssl command).
