| - | FTPS (also known as FTP Secure and %%FTP%%-%%SSL%%) is an extension to the commonly used File Transfer Protocol (%%FTP%%) that adds support for the [[tls|Transport Layer Security]] (TLS) cryptographic protocol (previously known as the Secure Sockets Layer – SSL).((&wikipedia_ref(FTPS|FTPS))) | + | ((&wikipedia_ref(FTPS|FTPS))) |

| - | Two separate methods were developed to invoke client security for use with %%FTP%% clients: //Explicit// or //Implicit//. The former method is a legacy compatible implementation where %%FTPS%% aware clients can invoke security with an FTPS aware server without breaking overall %%FTP%% functionality with non-%%FTPS%% aware clients. The latter method is an incompatible method that requires clients to be %%FTPS%% aware. WinSCP supports both methods. | + | To separate methods were developed to invoke lient security for use with %%FTP%% clients: //Explicit// or //Implicit//.

| - | In explicit mode, a %%FTPS%% client must "explicitly request" security from a %%FTPS%% server and then step-up to a mutually agreed encryption method. If a client does not request security, the %%FTPS%% server can either allow the client to continue insecure or refuse/limit the connection. | + | In exlicit mode, a %%FTPS%% client must "explicitly request" security from a %%FTPS%% server and then step-up to a mutually agreed encryption method.

| In Explicit Mode, the client has full control over what areas of the connection are to be encrypted. Enabling and disabling of encryption for the %%FTPS%% control channel and %%FTPS%% data channel can occur at any time. WinSCP though requests encryption for both control and data channel unconditionally during whole session. | In Explicit Mode, the client has full control over what areas of the connection are to be encrypted.
