How it works

Initial Authentication

- User on Computer A creates and configures a new computer entry for Computer B, with an associated password, and sends a request to initialize communication between the two computers.

- User on Computer B creates and configures a new computer entry for Computer A, with the same associated password, and sends a request to initialize communication between the two computers.

- When either computer receives the communication from the other it checks the authenticity and password (through SHA256 secure hashing) and if the request is authentic it responds with encryption key information to secure future communication and also sends the allowed directory structure information.

- When either computer receives the initialization response it stores the encryption key information and the directory structure to allow offline browsing. Once the computer has received its response it can now send commands to the other computer.

Example: Getting a file

- If the user on Computer A wants to get a file they:

browse Computer B's directory structure to the required file

initiate a copy command (e.g. Ctrl+C)

browse computer A's directory structure for the location to copy the file to

complete the copy command by pasting to the new location (e.g. Ctrl+V)

encrypts, signs, then sends the copy command to the remote Computer B

- Computer B, which should be periodically checking for email commands, receives the command from Computer A:

checks the authenticity of the email through encryption key and digital signature

fetches the file

compresses the information

encrypts, signs, and sends the information back to remote Computer A

- Computer A, which should also be periodically checking for email commands, receives the results from Computer B:

checks the authenticity of the email through encryption key and digital signature

uncompresses the information

saves the file into the specified local location
