LibreCrypt: Open-Source disk encryption for Windows
Please support with the recommended amount of $15 or £10
- Full transparent encryption, containers appear as removable disks in Windows Explorer.
- Compatible with Linux encryption: dm-crypt and LUKS. Linux shell scripts support deniable encryption on Linux.
- Explorer program lets you browse containers when you don't have administrator permissions.
- 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 many hash (including SHA-512, RIPEMD-320, Tiger) and encryption algorithms (Including AES, Twofish, and Serpent) in several modes (CBC, LRW, and XTS).
- 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 in case of 'rubber hose cryptanalysis'.
- Considered the most easy to use encryption program for Windows.
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 in version v6.3β
* Simplified open and create container dialogs by removing 'hidden' containers options * Creating hidden containers is now through separate dialogs, which is easier and less error prone * Added experimental feature to create LUKS containers * Minor UI improvements, including the option to remember the window position * Reviewed and simplified all the text used in the application to use less technical language
- A new menu time shows the recommended 'hidden' offset, so hidden containers can be used without memorizing a number
- More clearly separated LUKS and dm-crypt options in the UI, to prevent LUKs containers being accidentally opened as dm-crypt
New features in version 6.2β
- Change of name to 'LibreCrypt'
- Many UI bugs fixed - see Issue 20
- Improved support for GPT partitioned discs.
- Improved new password dialog.
- Improved partition information when running as non-admin.
Important: LibreCrypt in Portable mode will not work on Windows Vista and later 64 bit versions without a extra step before use.
* LUKs partitions on LVM volumes, or LVM volumes in LUKS partitions cannot be accessed due to Windows limitations * To run in portable mode, you need to have admin rights. * LibreCrypt does not support encryption of the operating system partition, for this we recommend Ubuntu Linux or DiskCryptor.
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.
* LibreCrypt cannot access LVM containers without an additional filesystem driver that understands LVM. No such filesystem driver exists for Windows versions later than XP * LibreCrypt cannot access ext2,3,4 volumes without an additional filesystem driver that can read ext2. * Installing the LibreCrypt drivers may enable malware specifically written to take advantage of it to access files as administrator [see issue #38](https://github.com/t-d-k/LibreCrypt/issues/38) * LibreCrypt may not be able to access internal disks where a LUKS volume was created using the whole volume, instead of a partition [see issue #30](https://github.com/t-d-k/LibreCrypt/issues/30)
* 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. * LibreCrypt needs to be run as administrator the first time it is run. After that it can be run as an ordinary user.
* This release has changes to the drivers, if upgrading from previous versions of LibreCrypt,DoxBox or FreeOTFE please completely uninstall the old version first * 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. * Backwards compatibility with older versions of FreeOTFE (before 5.21) will be removed in version 6.3. Please convert any FreeOTFE volumes. This can be done by creating a new 'container' and copying the files across.
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.
