Makes possible downloading and installing signed resource files from a server.
|
|
You must subclass it and implement the @ref installResource() pure
|
|
virtual method to install a resource. For uploading you must create a resource
|
|
tarball (which is installabale by @ref installResource()) and call the
|
|
@ref uploadResource() method with this tarball as the argument.
|
|
Signing and verification is done by the gpg application, so the user must
|
|
have it installed, otherwise this class does not give any extra security compared
|
|
to the standard TDENewStuff class.
