Step 2: Obtain the Server Certificate

  2. Copy the certificate imbedded in the body of the email and paste it into a text file using Vi or Notepad.

    The text file should look like:

             [encoded data]
    -----END CERTIFICATE-----
  3. Make sure there are 5 dashes to either side of the BEGIN CERTIFICATE and END CERTIFICATE and that no white spaces, extra line breaks or additional characters have been inadvertently added.
