Installation Instructions for Apache ==================================== To correctly install your certificate, it is important to configure the server to use the intermediate DigiCertCA.crt file in addition to dcl_coface_com_ar.crt. Our online Apache installation guide is available here: https://www.digicert.com/csr-ssl-installation/apache-openssl.htm#ssl_certificate_install A typical Apache installation will involve configuration lines like these in your block: SSLCertificateFile /your/path/to/dcl_coface_com_ar.crt SSLCertificateKeyFile /your/path/to/dcl_coface_com_ar.key SSLCertificateChainFile /your/path/to/DigiCertCA.crt (The dcl_coface_com_ar.key file refers to the private key which only you control. It was likely generated in the same place where your CSR was created on the day this certificate was ordered.) After installing your certificate, you can verify that it is correctly installed by using our Certificate Testing tool: https://www.digicert.com/help/ If you are having difficulty installing your certificate, please contact our friendly support team for more assistance.
