TrueCrypt is a program whose function is to encrypt files in order to protect them, so that they can not be opened by third parties. It can be very useful for saving important documents or spreadsheets, files with passwords, bank data or other confidential data. Also personal videos or photos.
TrueCrypt allows you to encrypt partitions whole, removable disks, and flash drives (USB flash drives). In turn, it also allows you to create virtual disks within some partition, which are recognized as a more disk drive.

Each time a file is copied to a space created with this application, it is automatically encrypted, without any need to specify anything. To access the protected area is necessary to enter a password previously defined, otherwise it will be impossible to decrypt its contents.

To optimize this aspect in large files, such as videos, TrueCrypt uses a batch decryption method, so that they can be opened and viewed while processing the following parts.
The application uses sophisticated encryption algorithms, such as Serpent, AES or Twofish, among others; Individually or in combination, which is a guarantee that they will not be able to break even by brute force methods.
