Verisign company provides SSL certificates in .cer format.  To be able to install certificate in Plesk it’s necessary to convert it to .pem format.

Please use the following command for converting:

“%plesk_bin%\openssl”  pkcs7 -in public.cer -print_certs -out certs.pem
There are two certificate parts in cert.pem file:

-          The first part is the certificate itself
-          The second one is CA certificate
