Apache Reference: mod_ssl, SSLCertificateFile
Server PEM-Encoded X.509 Certificate File
Syntax: SSLCertificateFile A
Example: SSLCertificateFile etc/ssl/host.crt
Since: Apache 1.3
This directive points with file to the PEM-encoded certificate
file for the server and, optionally, to the corresponding RSA or
DSA private key file for it (contained in the same file). If the
private key is encrypted, the pass phrase dialog (->
SSLPassPhraseDialog) is forced at start-up time. This directive can
be used a maximum of two times (referencing different file names) when both
RSA- and DSA-based server certificates are used in parallel.
