That could be anywhere on your system. During setup of the SSL you provided a directory where to install them. If you followed a how-to the most likely directory would be /etc/apache2/ssl
.
To make it easier to find the: the files are
ca.pem
private.key
sub.class1.server.ca.pem
ssl.crt
Beside that: your virtual host in /etc/apache2/sites-enabled/
will also have alterations to point to port 443 and have something like this:
SSLEngine on
SSLProtocol all -SSLv2
SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM
SSLCertificateFile /etc/apache2/ssl/ssl.crt
SSLCertificateKeyFile /etc/apache2/ssl/private.key
SSLCertificateChainFile /etc/apache2/ssl/sub.class1.server.ca.pem
(this is all based on the assumption you used apache and the often used /etc/apache/ssl/
in how-to's).
General searching for files in a tar.gz:
tar tvfz {tarfile}.tar.gz /etc/apache2/ssl/ /etc/apache2/sites-*/
will find it. tar xvfz
to extract files.
