Create encrypted tar files

# tar -zcf – todays_backup|openssl enc -aes-256-cbc -salt -pass pass:yourpassword -out todays_backup.tgz.aes-256-cbc

Replace yourpassword with a password of your own. Keep the password to yourself, and keep it carefully. The above command will generate a file called todays_backup.tgz.aes-256-cbc. This file can only be decompressed using this password.

To extract your protected archive file todays_backup.des3 use the following command:

# openssl enc -d -aes-256-cbc -out todays_backup.tgz
