Please take the survey on new features for LibreCrypt

Features

• Easy to use, with a 'wizard' for creating new 'containers'.
• Full transparent encryption, containers appear as removable disks in Windows Explorer.
• Explorer mode lets you access containers when you don't have admin permissions.
• Compatible with Linux encryption, Cryptoloop "losetup", dm-crypt, and LUKS. Linux shell scripts support deniable encryption on Linux.
• Supports smartcards and security tokens.
• Encrypted containers can be a file, a partition, or a whole disk.
• Opens legacy volumes created with FreeOTFE
• Runs on Windows Vista onwards (see note below for 64 bit versions).
• Supports numerous hash (including SHA-512, RIPEMD-320, Tiger) and encryption algorithms (Including AES, Twofish, and Serpent) in several modes (CBC, LRW, and XTS), giving more options than any other disk encryption software.
• Optional 'key files' let you use a thumb-drive as a key.
• Portable mode doesn't need to be installed and leaves little trace on 3rd party PCs (administrator rights needed).
• Deniable encryption protects you from 'rubber hose cryptography'.

Please note this is a Beta version with some known limitations. Particularly on 64 bit Windows the text 'Test Mode' is shown on the desktop.

New features in version 6.2

• Change of name to 'LibreCrypt'
• Many UI bugs fixed - see Issue 20
• Improved support for GPT partitioned discs. LUKS partitions on GPT discs have not been tested and should be used with caution.
• Improved new password dialog.
• Improved partition information when running as non-admin.

Release notes

Important: LibreCrypt in Portable mode will not work on Windows Vista and later 64 bit versions without a extra step before use.

LibreCrypt installed on Windows Vista and later 64 bit versions adds the text "Test Mode" to the Windows desktop. Please see the documentation for details on removing this. On Windows 8 please turn off 'Safe Boot' and disklocker before installing. There has been a report that Kaspersky anti-virus falsely reports LibreCrypt as having the 'generic.Trojan' virus, please disable or replace this before installing.

• Please follow these instructions to run LibreCrypt in portable mode on 64 bit Windows; if you do not do this you will get the error "Windows requires a digitally signed driver" when starting the drivers. There is no need to do this if LibreCrypt is installed.
  • Start LibreCrypt, click 'No' on the prompt to start the portable drivers, and 'OK' on the warning dialog about not having any loaded drivers.
  • Click the Tools->"Allow Test-signed drivers" menu item.
  • Reboot
  • After rebooting the words "Test Mode" appear in the four corners of the Desktop. Please see the documentation for details on removing this.
  • After finishing with LibreCrypt you can click the Tools->"Disallow Test-signed drivers" menu item to remove the "Test Mode" text.
• To run in portable mode, you need to have admin rights.
• Backwards compatibility with older versions of FreeOTFE (before 5.21) will be removed in a future version. Please convert any FreeOTFE volumes. This can be done by creating a new 'box' and copying the files across.
• Support for the following cyphers will be removed in a future version, please convert to another: xor, plain, single DES. Ditto for the 'plain' hash.
• LibreCrypt does not support encryption of the operating system partition, for this we recommend Ubuntu Linux.
• LibreCrypt needs to be run as administrator the first time it is run. After that it can be run as an ordinary user.

Passwords

These issues relate to passwords (keyphrases) containing non-ASCII characters, e.g. accented letters and non Latin scripts, not to ASCII special characters like '$&^'.

• The handling of keyphrases containing non-ASCII characters will change in a future version. This change will not be backwards compatible. So in this version it is recommended to use only ASCII characters in keyphrases.
• There are possible bugs in opening volumes created with FreeOTFE with non-ASCII characters. If you experience problems, please use the legacy app to change the password to an ASCII one and retry. Alternatively move the files to a native container.
