file_transfer
Inspired from https://github.com/TheAlgorithms/Python/file_transfer
python socket file transfer using ssh key for encryption/decryption
This project contains 3 python modules that can be called separately.
pyCryptoFile
This module can be called in command line : python3 pyCryptoFile.py -h
usage: pyCryptoFile.py [-h] [-V] [-f FILE] [-m {encrypt,decrypt}] [-k KEYFILE]
[-o OUTPUTFILE]
pyCryptoFile is a python3 program that encrypts, decrypts using ssh key encryption
optional arguments:
-h, --help show this help message and exit
-V, --version Display the version of pyCryptoFile
-f FILE, --file FILE file to encrypt/decrypt
-m {encrypt,decrypt}, --mode {encrypt,decrypt}
encrypt/decrypt mode
-k KEYFILE, --keyfile KEYFILE
public key file if encrypt mode or private key file if decrypt
mode
-o OUTPUTFILE, --outputfile OUTPUTFILE
outputfile by default it will be the file with .enc or .dec
extension
example to encrypt a file content and put in another file by default same as file with .enc extension :
python3 pyCryptoFile.py -f mytext2.txt -k ~/.ssh/id_rsa.pub
this generates a mytext2.txt.enc by default
example to decrypt a file content and put in another file :
python3 pyCryptoFile.py -f mytextcrypted.txt -k ~/.ssh/id_rsa -m decrypt -o mytext_decrypt.txt
This generates the mytext_decrypt.txt if -o option is missing it will generate mytextcrypted.txt.dec
This module provides some useful functions. You can find pycryptofile in pypi.
pySendFile
This module can be called in command line and starts the server in the listening port default 12312 :
python3 pySendFile.py -h
usage: pySendFile.py [-h] [-V] -f FILE [-hn HOSTNAME] [-p PORT] [-k KEYFILE]
pySendFile is a python3 program that creates a socket and transfers using ssh key encryption
optional arguments:
-h, --help show this help message and exit
-V, --version Display the version of pySendFile
-f FILE, --file FILE file to send
-hn HOSTNAME, --hostname HOSTNAME
hostname
-p PORT, --port PORT port number
-k KEYFILE, --keyfile KEYFILE
public key file
pyReceiveFile
python3 pyReceiveFile.py -h
This module can be called in command line and connects to the host/port and receives the data :
usage: pyReceiveFile.py [-h] [-V] [-f FILE] [-hn HOSTNAME] [-p PORT] [-k KEYFILE]
pyReceiveFile is a python3 program that connects to a socket and receives data encrypted using ssh key encryption
optional arguments:
-h, --help show this help message and exit
-V, --version Display the version of pyReceiveFile
-f FILE, --file FILE file to receive data
-hn HOSTNAME, --hostname HOSTNAME
hostname
-p PORT, --port PORT port number
-k KEYFILE, --keyfile KEYFILE
private key file
Examples
python3 pySendFile.py -f mytext.txt -hn localhost -p 12000
Server listening....
Got connection from ('127.0.0.1', 39704)
Server received: data = b'Hello server TOTO-7Z845TT'
Done sending
python3 pyReceiveFile.py -f result.txt -hn localhost -p 12000
File opened
Receiving data...
data = b'Hello\nThis is sample data\n\xc2\xabk\xc3\xbc\xc3\x9f\xc3\xae\xc2\xbb\n\xe2\x80\x9c\xd0\x8c\xcf\x8d\xd0\x91\xd0\x87\xe2\x80\x9d\n\xf0\x9f\x98\x80\xf0\x9f\x98\x89\n\xf0\x9f\x98\x8b\n'
