VeraCrypt is a free open source disk encryption software for Windows, Mac OSX and Linux. Brought to you by AM Crypto (https://amcrypto.jp) 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.
