How to encrypt text file in Linux (VIM)
It is very easy to encrypt a text file in Linux, VIM text editor can be used to achieve it.. vim -x [file name]
[kartook@Nilas ~]$ vim -x kartook.txt
This will prompt us to enter encryption key (password)
Enter encryption key : ******
Enter same key again: ******
After that, key in the text data and save it. Now the “kartook.txt” text file is encrypted with my password.

The text file content is encrypted with some alien code 🙂 ,
Done, no body can view the content unless they know my encryption key.
