cert=	client side certificate and private key

Convert .cer into .pem:
	open, export as Bse64 encoded (this will be the host certificate, e.g. cert.pem
	2. from the tree open intermediate certificate and save in the same way
	3. from the tree-tab of host or intermediate cert open root certificate and export in Base64
	4. append content of int and root certificates into cert.pem (ordermatters: cert,int,root at the end)
