VeraCrypt is a free open source disk encryption software for Windows, Mac OSX and Linux. Based on TrueCrypt 7.1a. 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 and hidden operating system.
- 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.
