FTP/SSL (AUTH SSL, TLS)

Download Chilkat FTP2 ActiveX

Demonstrates how to connect using AUTH SSL. 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.
