We need to start thinking about the future now. Current encryption methods will no longer be state of the art in the near future.
Due to the rapidly increasing computing power of quantum computer technology, it will be possible in a few years to decrypt files and VPN connections with today's encryption standard in a short space of time and without great effort.
In order to counteract this development, the responsible institutes such as BSI and ANSII are already working on a new encryption standard that will remain secure in the future.
