TrueCrypt is a utility that generates an in-file encrypted disk that is able to be mounted as a real disk, with support for encrypting both internal and external storage devices and partitions.
As TrueCrypt has been discontinued for several years, its development has been succeeded specifically by VeraCrypt and CipherShed. Most importantly, both of those alternatives that serve as successors are also in active development.
Outside of CipherShed and VeraCrypt, there are free and open source alternatives to TrueCrypt available on all major operating systems, including Android and iOS.
