TrueCrypt – Free Open-Source Disk Encryption Software
Clever program to encrypt data on disks such as USB flash drive or hard drive. It uses following very strong encryption algorithms: AES-256, Serpent, and Twofish. There is also a nice option to create a virtual encrypted disk within a file and mapping it as a real disk. Encryption is automatic, real-time (on-the-fly) and transparent. The latest version supports hardware-accelerated encryption but of course only when processor has such possibility. System encryption provides the highest level of security and privacy because all files including all temporary files that Windows and some applications created on the system partition (usually without your knowledge or consent), hibernation files, swap files, etc., are always permanently encrypted (even if power supply is suddenly interrupted). An interesting new feature is also Volumes Favorite Organizer that allows you to manage encrypted partitions and containers from one place and also to configure their advanced options. TrueCrypt 7.0 supports the creation of encrypted partitions on the disk sector size of 4096, 2048, and 1024 bytes (both Windows and Linux). Previously on these kinds of disks you was able only to create a file containers. Moreover, you can interrupt the process of encryption or decryption anytime, leave the partition/drive partially unencrypted, restart or shut down the computer, and then resume the process, which will continue from the point it was stopped.
