Ubuntu / Linux news and application reviews.

diskcryptorDiskCryptor is the only truly free disk encryption solution for Windows, provided under GNU General Public License (GPLv3), which offers encryption of all disk partitions, including the system partition. The application can encrypt hard disks, partitions, pen drives or CD / DVD, having a very low impact on performance. If you want to keep your data private, you should really try this application!

On the Intel Core 2 Quad Q6600 CPU, data encryption speed amounts to 104Mb/s per core. The maximum speed of reading the data from a single hard disk, equals to 80Mb/s, thus consequently, one can work with up to 5 different disks without the loss of performance, when using the aforementioned type of processor.

The encryption is performed on AES, Twofish, AES-Twofish, Serpent, Serpent-AES and others, so we will not be short in terms of security options. That if, in the case of CD / DVD and USB flash drives, one must bear in mind that to take them to another site and to use them, there also need to have installed DiskCryptor.
