E2EE client

Encrypts files and uploads them to the E2EE server.

E2EE client provides end-to-end encryption. The files dragged into E2EE client get encrypted and are sent to the E2EE server. When needed, the files are downloaded from the E2EE server and decrypted locally. The server is to be found on https://github.com/xlab-si/e2ee-server. The server address needs to be specified in the E2EE client login window. The server never knows the contents that it is storing because the files and file names are encrypted locally on the user's machine using E2EE client. Files can be shared to other users.
