Data can be transferred between two computers using Socket programming in C.
Similarly, files can easily be sent using UDP protocol and a simple client/server.
Security: Handled by encryption.
Protocol : UDP
Encryption: XOR encryption
1. The server starts and waits for filename. 2. The client sends a filename. 3. The server receives filename. If file is present, server starts reading file and continues to send a buffer filled with file contents encrypted until file-end is reached. 4. End is marked by EOF. 5. File is received as buffers until EOF is received. Then it is decrypted. 6. If Not present, a file not found is sent.
The Server :
