Encrypting files and drives
Tools
The menu item zC | erase data in a device gives particularly security-conscious zuluCrypt users the option of deleting existing data physically from a container. For this purpose, it overwrites the entire container contents with random characters, making a reconstruction of previously existing data impossible. The container itself is kept. To enable the secure delete function, you must first unmount the encrypted drives. You cannot purge unnecessary data files from mounted drives.
Conclusions
ZuluCrypt gives users a small but powerful encryption program that is suitable for every need due to its diversity of functions. In the lab, the software was very stable and ran without the slightest problem. The program impressed with its fast speed: creating encrypted drives with multiple-gigabyte sizes was achieved within a short time, and even deleting larger containers took just a few seconds.
The biggest shortcoming of zuluCrypt turned out to be the lack of distribution packages, which makes the installation process cumbersome and time-consuming. However, once you have overcome these hurdles, zuluCrypt gives you a highly useful tool that can significantly increase the security of your personal information.
