Introduction:

PyDrop was written as a side project but also has practical applications! Use PyDrop to transfer files securely over SSL/TLS or unsecurely! Quickly transfer files from one host to another whether your playing a CTF, performing a penetration test or carrying out general administration.

PyDrop is designed to be deployed quickly and easily in any environment that supports the Python programming language, on both Windows and Linux.

Prerequisites:

PyDrop requires the following prerequisites to work:

• Python 3.x
• A certificate file (for use in encrypted mode)
• A key file (for use in encrypted mode)

To use TLS, PyDrop requires you to specify a certificate and a private key using the -c and -k flags. To create your own certificate and key, you can use the openssl command:

• openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

Note this will create a "self-signed certificate", which by default PyDrop will accept without warning.

Usage:

By default, the PyDrop server listens on port 9090/tcp, this can be changed using the -p flag, similarly PyDrop will listen on all interfaces 0.0.0.0, this can be changed using -H.

• Start an Unencrypted Server on port 9090/tcp: PyDrop.py server
• Connect to Unencrypted PyDrop Server: PyDrop.py client --host <IP> --port <PORT> --filename <FILENAME_TO_FETCH>
• Start an Encrypted Server on port 9090/tcp: PyDrop.py server --encrypted --certfile ./server.crt --keyfile ./server.key
• Connect to Encrypted Server: PyDrop client --encrypted --host 127.0.0.1 --port 9090 --filename <FILENAME_TO_FETCH>

python .\PyDrop.py -h
