Active

truecrypt.org · DevTools

TrueCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, TrueCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by TrueCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files.
