This area allows you to upload one or more client certificates to use while authenticating with HTTPS servers. These are normally not needed unless the remote server requires a client certificate for authorization.
Adding a new certificate requires providing the certificate and key each in PEM
format (with the BEGIN PRIVATE KEY/END PRIVATE KEY
and
BEGIN CERTIFICATE/END CERTIFICATE
blocks, respectively).
Client certificates uploaded here can be chosen for use with the
Client Certificates
profile setting (3.5.71). The same
client certificate can be used by multiple profiles.
