FTPS channel configuration queries

Hi Experts,

I am using FTPS for the first time so have some questions: SAP PI 7.1 version:

>Where exactly should I ask Basis to keep the X.509 public certificate(which I have got from the third party system) in certificate keystore? Can you please share the navigation path in certificate keystore?

>In FTPS channel, what value has to be configured in "Keystore" and "X.509 Certificate and Private Key" ?

Thanks in advance, Surya
