VeraCrypt is a free open source disk encryption software for Windows,
Mac OSX 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.
* Parallelisation 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. |
