WebSilver: Silver Key's Frontend to the Web

WebSilver is Silver Key’s frontend to popular Web storage services. WebSilver is the further development of Silver Key uploaders, specifically designed to make secure file exchange as easy and simple as possible.

WebSilver main window

WebSilver’s main window looks very similar to Windows Explorer. The left pane shows the supported Web services, and the right one shows the contents of the selected folder. Drag and drop a file there, and WebSilver will encrypt the file and will upload the encrypted parcel.

Hint: you can drop several files and/or folders.

Hint: dragging with the right mouse button will open the parcel format menu.

In order to get the file back double-click the parcel. WebSilver will download and decrypt it.

Exchanging data with other people

Shared folders is the standard file exchange mechanism offered by Web storage services. Create a folder and allow your correspondents access to it. You need to consult the selected Web service’s documentation for details on folder sharing.

When the folder is created and shared, open it in WebSilver and drop a file there. The recipient can access the Web storage directly with a Web browser, but the recommended way is using WebSilver, which downloads and decrypts data transparently.

You can also get a direct download link with WebSilver’s Edit / Get Download Link command and send that link by email.

Which parcel format to use?

The two basic Silver Key formats are self-extracting (.exe) parcel, and standard (.sk) parcel. If your correspondent does not have Silver Key installed, send self-extracting parcel. Otherwise standard parcel will be the best choice.

Hint: open Settings / Web Storage to set the default parcel format.


Although WebSilver mimics Windows Explorer, in reality it is based on rather slow and very limiting Web services. This leads to some limitations, which may look somewhat illogical.

  • After some period of inactivity the Web service may perform a silent logoff. There is no way for the program to detect this reliably, so automatic reconnect is not possible. If you get a persistent error ‘Unauthorized’ or similar, use command File / Reconnect Storage to log on again.
  • Some commands may be unavailable. For example, Dropbox does not allow renaming items.
  • Drag-and-drop is one way only. The reason is that in order to start dragging from the storage, the program needs to know what to drag, and it is not known until the parcel is downloaded and decrypted.
