TrueCrypt TrueCrypt provides free open-source disk encryption software for Windows 7/Vista/XP, Mac OS X, and Linux. It creates a virtual disk that is entirely encrypted (including file names, folder names, contents of every file, allocation tables, free space, meta data, ect.) and mounts as if it was a real disk. It can encrypt an entire partition or storage device such as a USB flash drive or hard drive. The encryption is automatic, fast, and transparent to the user. You can copy files and folders to and from a mounted TrueCrypt volume just like you would normally do. Keep in mind that after you drag-and-drop all your sensitive data into your TrueCrypt volume, you should securely erase the original unencrypted files. TrueCrypt does not save any decrypted data to a disk rather it only stores data temporarily in RAM (memory).

Important: Note that when you open a file stored on a TrueCrypt volume (or when you write/copy a file to/from the TrueCrypt volume) you will not be asked to enter the password again. You need to enter the correct password only when mounting the volume. In order to close the volume and make your files inaccessible click Dismount.
