Is it possible to encrypt all files in a folder including their file names but totally without compression...
I have a folder with several files:
file1
file2
file3
I want to encrypt them all with AES including the file names so the output should be something like this:
kjk437fjk437
3k4jn34jk
j34nkj34
But I do not want to apply any compression at all.
Is it possible to do this with 7zip? I am using Debian and looking for Terminal based solutions only.
Edit: I also want to be able to get the filename back after decryption.

Please clarify your requirements: why do you need to avoid compression?

You probably just want to hide the filename instead of to encrypt it, so something like the following should do:
for file in ./*;do
7z a $RANDOM-$RANDOM.7z -m1=copy -mhe -psecret "$file";
rm "$file"
done
-m1=copy means use copy method, so no compression.-mhe means encrypt header, so without password one cannot view filenames inside the 7z file.-psecret sets password to secret

@Vesa the original filename is stored in the archive. You get the original file + filename back just by extracting it.

And this also AES encrypts the content of the file?

Is 7zip a must? Choose the right tool. EncFS seems to be it.
- Install it. In Debian:
apt-get install encfs. Create two directories:
mkdir encrypted mountpoint.
Run the tool:
encfs "$PWD/encrypted" "$PWD/mountpoint"
Note you need
$PWD/instead of./becauseencfsdoesn't accept relative paths (unless-fis used).
Proceed as instructed to choose encryption, password.
Copy or move all directories and files you want to encrypt to
./mountpoint. Encrypted directories and files will appear in the./encrypteddirectory.
Unmount:
fusermount -u ./mountpoint
You can now copy/move/rename/tar/whatever the ./encrypted directory as a whole. Note there is a hidden .xml file inside. The file includes the (password protected) key which is crucial, so don't lose it. It's possible to store the file separetely (read about ENCFS6_CONFIG variable in man 1 encfs).
To access the original files, repeat step 3, provide the right password. Work with files under the chosen mountpoint: read, add, remove, modify, anything goes. Finally unmount with fusermount -u like in step 6.
Notes:
encfsis FUSE (filesystem in userspace). See Why FUSE might be considered insecure on server?
- There are also EncFS-specific security concerns.

@Vesa It's somewhat disappointing you knew aboutencfsand you knew you can't use it now, still you didn't explicitly ruled it out. I did notice you're asking about a 7zip solution; but sticking to some tool is often a Y in XY problem, while good answers should concentrate on X and this is what I was trying to do. The answer will stay (with other users in mind), unless you change the question so it clearly saysencfsis not an option. Regardless, I do hope you'll get an answer that fits you. Good luck.
