Open-source disk encryption with plausible-deniability features.

VeraCrypt is a free, open-source application for encrypting disks and protected volumes on Windows, Mac OS X, and Linux. It encrypts data transparently as it is used, aiming to avoid leftover unencrypted temporary files while keeping memory use low.

Why it stands out

  • Focuses on disk and volume encryption rather than only encrypting individual files.
  • Designed to avoid creating temporary unencrypted copies during normal encrypted-data use.
  • Cross-platform desktop support covers the major operating systems named on the site.
  • Plausible-deniability support addresses a threat model many encryption tools do not explicitly cover.

Good to know

  • Protects disks or encrypted volumes rather than serving as a lightweight one-off file-encryption utility.
  • The listed platform support is desktop-focused: Windows, Mac OS X, and Linux.
  • Plausible-deniability setups require careful use; they are not a substitute for understanding the security model.
