VeraCrypt

VeraCrypt is disk encryption software with strong security, based on the original TrueCrypt 7.1a and extended with security enhancements and modifications. It protects your data at the disk level rather than file by file, so volumes stay encrypted on the devices you use locally.

It runs on Windows, macOS, Linux, and FreeBSD. By default the build produces a universal executable with both a graphical interface and a text-mode interface; on Linux you can also build a console-only version that needs no GUI libraries, which suits headless and server use.

Official Windows binaries are digitally signed, and the source ships pre-built EFI boot loader binaries so the platform can support encrypting the system boot volume.
