Hi there. I'm trying to do the following using python 3: create a list
from all files in a particular directory, then loop over that list
symmetrically encrypting each file using the gnupg module (note, for the
moment I'm embedding the passphrase in the code while obviously in
practice it would have to be inputted by the user).
I start with the following which can be used to encrypt a single file
(assume I have the indentations correct in the actual code, I can't seem
to modify the wrapping with my email client):
phrase = '12345'
cipher = 'AES256'
gpg = gnupg.GPG(gnupghome='/home/adam/.gnupg')
with open('/home/adam/file1', 'rb') as f:
status = gpg.encrypt_file(f, None, passphrase=phrase,
symmetric=cipher.upper(), output='/home/adam/file1.gpg')
Here you are giving with open( ) a full path to file1
This produces a single encrypted file, 'file1.gpg'. I then try to embed
this in a for loop:
unencrypted = [u for u in os.listdir('/home/adam/temp')]
If I run this code with my info and print it, I get a list of files in
my temp directory.
for G in unencrypted:
gpg = gnupg.GPG(gnupghome='/home/adam/.gnupg')
phrase = '12345'
cipher = 'AES256'
with open (G, 'rb') as f:
status = gpg.encrypt_file(f, None, passphrase=phrase,
symmetric=cipher.upper(), output=G + '.gpg')
If I then do:
for G in unencrypted:
print(G)
I get just a file name printed on each line.
When you do:
with open (G, 'rb') as f:
I think you have lost the path info for the files. If you give with
open() path info it should work. Hopefully if I am wrong someone with
more knowledge will step in and give you a better answer.

This produces the following error:
Traceback (most recent call last):
File "<pyshell#8>", line 5, in <module>
with open (G, 'rb') as f:
FileNotFoundError: [Errno 2] No such file or directory: 'file1'
It seems 'G', which I'm intending to represent each successive element
of the list as the for loop iterates, does not find its way into the
gnupg code lines. I have a feeling I'm missing something really basic
here :)
