File AES Crypt on Linux

Using AES Crypt on Linux


You do not need to be an expert to use AES Crypt for Linux to securely
encrypt your data files. To encrypt a file, you simply enter the
"aescrypt" command with the approrpiate command-line arguments.



Suppose you have a file called "picture.jpg" that you would like to
encrypt using the password "apples". You would enter the following
command:


aescrypt -e -p apples picture.jpg



That's it! The program will create a file with the name "picture.jpg.aes".



When you want to later decrypt the file "picture.jpg.aes", you would
enter the following command:


aescrypt -d -p apples picture.jpg.aes



The program will create the file "picture.jpg", containing the contents of the
original file before it was encrypted.



It can't be any simpler than that!



Of course, many Linux users create sophisticated scripts that pipe input from
one program into another, and AES Crypt fully supports such usage. For
example, you could backup files and encrypt them with a command like this:


tar -cvf - /home | aescrypt -e -p apples - >backup_files.tar.aes



In all of the examples above, the password is provided on the command
line. Since there are certain risks associated with that kind of usage,
it may be preferred to let aescrypt prompt you to enter the password.
This can be accomplished simply by not including the -p parameter,
like this:


aescrypt -d picture.jpg.aes



AES Crypt will prompt you for the password, but what you enter will not be
displayed on the screen.



What if you want to decrpyt a file, but just want to have it displayed on
the screen and not stored in a plaintext file? That's possible. To do
that, just use this syntax:


aescrypt -d -o - passwords.txt.aes
