All Implemented Interfaces:

Configurable
```
public class FTPSClient
extends FTPClient
```
FTP over SSL processing. If desired, the JVM property -Djavax.net.debug=all can be used to see wire-level SSL details. Warning: the hostname is not verified against the certificate by default, use setHostnameVerifier(HostnameVerifier) or setEndpointCheckingEnabled(boolean) (on Java 1.7+) to enable verification. Verification is only performed on client mode connections.
