To install an SSL certificate for Citrix Access Gateway 5.0, perform the following steps.

Step 1: Install SSL certificate

The COMODO SSL Certificate will be sent by email. The certificate click on the link to extract the zip file, copy and paste it into a text editor (save as cert.pem) such as Notepad or Notepad ++. Do not use Microsoft Word or other word processing programs that may add characters. Confirm that there are no extra lines or spaces in the file.

The text file should look like:

-----BEGIN CERTIFICATE-----
[encoded data]
-----END CERTIFICATE-----

Make sure there are 5 dashes to either side of the BEGIN CERTIFICATE and END CERTIFICATE and that no white space, extra line breaks or additional characters have been inadvertently added.
