The certificates in the crts directory has never been used.

Because when proxy starts, we will set the RootCertificate, this will delete the crts directory in the disk.

So we either use the newly created certificate (and save it in the crts directory and the cache variable cachedCertificates), or use the certificate in the cachedCertificates, but never use the certificate in the crts directory.

If so, it doesn't make sense to save the certificates to the disk crts directory.

Thanks!
