VeraCrypt is a free open source disk encryption software for Windows, Mac OSX,
FreeBSD and Linux. Brought to you by IDRIX (https://www.idrix.fr) and based on
TrueCrypt 7.1a.

VeraCrypt main features:

- Creates a virtual encrypted disk within a file and mounts it as a real disk.
- Encrypts an entire partition or storage device such as USB flash drive or
  hard drive.
- Encrypts a partition or drive where Windows is installed (pre-boot
  authentication).
- Encryption is automatic, real-time(on-the-fly) and transparent.
- Parallelization and pipelining allow data to be read and written as fast as
  if the drive was not encrypted.
- Encryption can be hardware-accelerated on modern processors.
- Provides plausible deniability, in case an adversary forces you to reveal the
  password: Hidden volume (steganography) and hidden operating system.
- More information about the features of VeraCrypt may be found in the
  documentation
