In order use WebCourier, it must interact with your local file system so that you can add files. You are asked because your system is by default set not to allow access to your local files. For WebCourier to function, you must click on Trust/Yes when asked if you trust an applet.

WebCourier uses a HTTPS connection, the same as used for payment and sensitive transactions on the web. HTTPS creates a secure channel and protects from eavesdropping and man-in-the-middle-attacks. Before your files leave your computer, they are secured with 2048-bit RSA encryption, which is equal to, or higher than industry standards.

In comparison, the normal FTP specification is an inherently unsecure method of file transfer that allows the files to be easily intercepted by unauthorized persons.
