I wrote a simple python script to encrypt (and then decrypt) a configuration file, using cryptography.fernet library. They work as expected on Linux systems, otherwise on Windows systems every time I decrypt the file it adds a newline in between every line. For example, if this is my config file:
[config]
user = test
psw = testtest
[utils]
ip = xx.xx.xx.xx
after encryption and then decryption, on Windows systems it becomes like this:
[config]
user = test
psw = testtest
[utils]
ip = xx.xx.xx.xx
Sometimes after this behavior the script doesn't work, for it everything is on the same line.
Is it an encoding issue?
This is the encryption script:
#!/usr/bin/env python
from cryptography.fernet import Fernet
# variables
config_file = r"configFile.txt"
encrypted_file = r"configFile.txt"
key_file = r"key_file.txt"
try:
# generate key
key = Fernet.generate_key()
# read config file
with open(config_file, "rb") as f :
data = f.read()
# encrypt data
fernet = Fernet(key)
encrypted = fernet.encrypt(data)
# write encrypted file
with open(encrypted_file, "wb") as f :
f.write(encrypted)
# write file with key
with open(key_file, "wb") as f :
f.write(key)
except Exception as error :
print(f"Error: {error}")
And this is the decryption script:
#!/usr/bin/env python
from cryptography.fernet import Fernet
# variables
key_file = r"key_file.txt"
encrypted_file = r"configFile.txt"
decrypted_file = r"configFile.txt"
try:
# read key file
with open(key_file, "rb") as k :
key = k.read()
# read encrypted file
with open(encrypted_file, "rb") as f :
data = f.read()
# decrypt file
fernet = Fernet(key)
decrypted = fernet.decrypt(data).decode()
# write file unencrypted
with open(decrypted_file, "w") as f :
f.write(decrypted)
except Exception as error :
print(f"Error: {error}")
Thanks in advance for any help.
