Nachdem ein Peer einen Offer erhalten hat, sollte dieser sich per TCP mit dem Server verbinden und die Datei gesendet bekommen.

Dies kann nicht über die gleiche Verbindung gemacht werden, da der Server an Broadcast sendet.

• Progressbar (c814538)
• Ability to specify destination of the transferred file (and even the output name)
  • Output directory (126c9a1)
  • Output filename (0f57fd6)
• Ability to specify multiple files
• Ability to specify a whole directory
• Make it work over the internet, not only in LANs (3d567a3)
• Human-readable file sizes (c70e674)
• Resume intercepted transfers
• Usage of UNIX-like CLI-flags (0bb443b)
• Relaying (Client <-> Server <-> Client)
• Encryption (Branch feature/encryption) -> See #4
• Ability to specify the other side (3d567a3)
• Encode the transmit-requests via protobuf not JSON
• Ability to run the upload and download in parallel
• Ability to disable the integrity checks (03cbcba)
• Password-protection
• Daemon-Mode (37760f1)

There should be a check, if the file got transferred correctly.

The transmitFileRequest should have a Hash-field which gets filled by the hash of the file. After the client recieved the file, he should build a hash and compare both.

There are three ways to do encryption:

• Just TLS
• Encrypt the file with PGP, secure the transfer with TLS
  • Use an existing key or generate a temporary key on the fly
• Encyrpt the file with AES, secure the transfer with TLS
  • How do we exchange the passphrase?
    • Could be made by elliptic curves
