PowerTCP SSL for ActiveX

PowerTCP SSL for ActiveX Features

 

SecureFtpServer ActiveX Control

 

Use the SecureFtpServer control to create FTP server applications which can transfer files using SSL, TLS, or PCT. Features include:

 

• Use SSL 2.0, SSL 3.0, PCT, TLS or unencrypted FTP communications.
• Customize certificate acceptance or rejection.
• Client authentication fully supported.
• Uniquely capable of SSL over FTP through a Firewall using Dart's proprietary FirewallReady functionality (requires PowerTCP products on both sides of the connection).
• The SecureFtpServer control uses an internal Daemon object and dynamically creates internal TCP objects as each passive connection is automatically accepted. Use this TCP object to send and receive data to that individual connection.
• When a request is received, a corresponding event is raised. Write your own custom handling code in the event handler.
• Add authentication and customized user directories within the Login event.
• Disallow changing directories within the ChangeDirectoryUp and ChangeWorkingDirectory events to those who do not have proper permissions.
• Disallow directory creation/deletion within the MakeDirectory and RemoveDirectory methods to those who do not have proper permissions
• Disallow file upload/download within the Retrieve and Store event to those who do not have proper permissions.
