VeraCrypt 1.23 for Linux was used in the screenshots below (in Ubuntu 18.10). You may also encounter different options depending on the operating system you're using (for example the filesystem types), but the important steps should be the same. It should be noted that you can create an encrypted USB flash drive on Linux, Windows and macOS using VeraCrypt in a similar way, but the VeraCrypt user interface may look slightly different. This article explains how to encrypt a USB drive with VeraCrypt with step-by-step screenshots, including what partition type to choose if you want it to be compatible with multiple operating systems (Linux, Windows, macOS), as well as how to mount / access the encrypted USB drive. The application was forked from the TrueCrypt project, and since then it got security improvements along with optimized implementations of cryptographic hash functions and ciphers which boost performance on modern CPUs. In Windows, it can also encrypt the entire storage device with pre-boot authentication. VeraCrypt is a free and open source disk encryption utility that can create a virtual encrypted disk within a file or encrypt a partition.
