VeraCrypt is free disk-encryption software. It can create an encrypted virtual disk inside a file, encrypt whole partitions or drives and encrypt the Windows system partition. It runs locally on Windows, macOS and Linux (FreeBSD is also mentioned) and is based on TrueCrypt 7.1a with security enhancements. It is meant for organisations and individuals who want to protect data on laptops, USB drives or backups without relying on a cloud service.
According to the project site, VeraCrypt is brought to you by AM Crypto, based in Kobe, Japan; the licence text also names IDRIX. The source code is public and covered by a combination of the Apache License 2.0 and the TrueCrypt License 3.0. The second licence is not approved by the OSI, so do not treat VeraCrypt as open source in the strict sense without checking the terms. The software runs entirely on your own device: keys and data are not sent to the developer. The developer is based outside the EU.
