Portable TrueCrypt 6.2a

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). Files are automatically being decrypted on-the-fly (in memory/RAM) while they are being read or copied from an encrypted TrueCrypt volume.

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. 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. There are no extra memory (RAM) requirements for TrueCrypt.

Major Features:

1. Create a virtual encrypted disk within a file and mounts it as a real disk.
2. Encrypt an entire partition or storage device such as USB flash drive or hard drive.
3. Encrypt a partition or drive where Windows is installed (pre-boot authentication).
4. Encryption is automatic, real-time (on-the-fly) and transparent.
5. Provide two levels of plausible deny, in case an adversary forces you to reveal the password:
   • Hidden volume (steganography ? more information may be found here).
   • No TrueCrypt volume can be identified (volumes cannot be distinguished from random data).
6. Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS

Enhancements:

• Improvements and bug fixes:
• • Improved file container creation speed on systems having issues with write block sizes greater than 64 KB. (Windows)
  • The Device not ready error will no longer occur when the process of decryption of a system partition/drive is finished. (Windows)
  • Other minor improvements and bug fixes. (Windows, Mac OS X, and Linux)
