In this tutz, I will discuss how to easily and quickly encrypt and decrypt files using very simple commands on Ubuntu
First install ccrypt on Ubuntu using this command:

sudo apt-get install ccrypt

For Debian, run these commands:

su -
apt-get install ccrypt

To encrypt a file, cd to its folder and run this command:

ccrypt file_name

Replace “file_name” with the name of your file. You will be asked to submit a password two times. The encrypted file will have the .cpt extension.
To decrypt the file, use now this command and provide the password you assigned to it:

ccrypt -d file_name
