In essence, it’s a free alternative encryption software which only available for free to Vista Ultimate and Enterprise editions users, as part of Ultimate Extras package.
TRUECRYPT 7.2 BUGS MAC OS
To make them accessible again, you have to mount the volume (and provide the correct password and/or keyfile).TrueCrypt is a free open-source disk encryption software for Windows Vista, Windows XP, Mac OS X, and Linux. Even when power supply is suddenly interrupted (without proper system shut down), files stored in the volume are inaccessible (and encrypted). When you restart Windows or turn off your computer, the volume will be dismounted and files stored in it will be inaccessible (and encrypted). Even when the volume is mounted, data stored in the volume is still encrypted. Note that TrueCrypt never saves any decrypted data to a disk – it only stores them temporarily in RAM (memory). This process is called on-the-fly encryption/decryption and it works for all file types (not only for video files). While this portion is being played, the media player begins loading another small portion of the video file from the TrueCrypt-encrypted volume to RAM (memory) and the process repeats. The decrypted portion of the video (stored in RAM) is then played by the media player. While the portion is being loaded, TrueCrypt is automatically decrypting it (in RAM). The media player then begins loading a small initial portion of the video file from the TrueCrypt-encrypted volume to RAM (memory) in order to play it. When the user double clicks the icon of the video file, the operating system launches the application associated with the file type – typically a media player. The user provides the correct password (and/or keyfile) and mounts (opens) the TrueCrypt volume. avi video file stored on a TrueCrypt volume (therefore, the video file is entirely encrypted). For an illustration of how this is accomplished, see the following paragraph.Let's suppose that there is an. There are no extra memory (RAM) requirements for TrueCrypt. Note that this does not mean that the whole file that is to be encrypted/decrypted must be stored in RAM before it can be encrypted/decrypted. Similarly, files that are being written or copied to the TrueCrypt volume are automatically being encrypted on the fly (right before they are written to the disk) in RAM.
Files are automatically being decrypted on the fly (in memory/RAM) while they are being read or copied from an encrypted TrueCrypt volume. Files can be copied to and from a mounted TrueCrypt volume just like they are copied to/from any normal disk (for example, by simple drag-and-drop operations). Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc). No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys.
On-the-fly encryption means that data is automatically encrypted right before it is saved and decrypted right after it is loaded, without any user intervention.
TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device).
