VeraCrypt is an open-source encryption software designed to secure files and drives. A direct successor of the TrueCrypt project, VeraCrypt uses a range of encryption algorithms to improve its predecessor's security capabilities, including AES, TwoFish, and Serpent ciphers in various combinations. The software allows users to create encrypted virtual disk volumes (containers) or encrypt entire partitions on storage devices such as USB drives and hard disks. VeraCrypt supports Windows, macOS X, and Linux platforms. As it is open source software new releases are tested by researchers around the world for vulnerabilities in real time which makes it less likely a backdoor could be implanted unnoticed like what happened with Truecrypt in 2014 when Microsoft stopped supporting Windows XP.
