(SQL Server) FTP using Explicit SSL/TLS (AUTH TLS, AUTH SSL, FTPES)

Demonstrates how to connect using AUTH SSL (also known as FTPES). By setting the AuthTls property, a secure FTP connection can be established using either SSL 3.0 or TLS 1.0. The Chilkat component will automatically choose whichever is supported by the FTP server during the secure channel establishment. The FTP control port remains at the default (21). Upon connection, the channel is converted to a secure channel automatically. All control messages and data transfers are encrypted.
