Cryptic Disk versions

v4.1 [Nov 17, 2014]
- An option has been added that allows the user to disable changes to buttons in the system panel if there are mounted encrypted volumes.
- An option has been added that allows the user to disable program icons in the system panel while the program is still running.
- Dynamic volumes can now be accessed via an icon in the system panel.
- If a new version of the program is available on the server a notification will appear in the system panel. In this case a dialog window with information about the new version will not appear automatically.
- The process of updating the program while a copy of the program is open has been improved.
- A bug that made it so that hidden encrypted volumes could only be mounted in a registered version of the program has been fixed. Hidden encrypted volumes can now be used during the trial period.
- Using key files with a size of zero no longer causes an error. These files will be ignored.
- A number of minor fixes and improvements.

v3.2 [Jan 28, 2014]
- Increased the speed of lossless encryption of physical drive volumes.
- When creating a new encrypted container on volumes with the NTFS file system, the container file was previously filled with zeros, which resulted in the long creation of large containers. From now on, the program will disable the filling of newly created files with zeros (requires the program to be launched with admin rights)
- Fixed the support of physical drives with 4 kb sectors.

v3.0 [Aug 11, 2010]
The following error has been corrected: in Windows XP and Windows 2003 Server operating systems, any encrypted container just mounted would immediately unmount.
The encrypted container creation wizard now uses the default path as the value of the file path input field.
The default container size in the encrypted container creation wizard has been increased to 20 MB.
If the program cannot complete the formatting of an encrypted volume or container, it displays a notification with a description of the problem. For instance, when an encrypted container is created, the program will not be able to format it if it was started with lower privileges.
Improved UAC (User Account Control) support. When an action requiring higher privileges is executed, the program automatically restarts with higher privileges and opens a window corresponding to the selected action.
Added the OFN_DONTADDTORECENT flag to all file selection dialogs that prevents the system from remembering the paths specified by the user.
Added the Hungarian localization.
Fixed the Russian localization.
Added a content tree to the program manual.
Fixed a bug that could cause the program to freeze or crash when mounting or using encrypted volumes on multi-processor (or multicore) platforms.
The “Tip of the day” window is not shown automatically when the program is launched with command line parameters.
Double-clicking the “Unmount” button on the toolbar could cause the program to freeze if the encrypted volume was being used by other programs at that moment.
The interface of the program has been completely redesigned.
The algorithms used for protecting data on encrypted disks, have been heavily modified, which enabled us to drastically improve the data protection aspect of the program.
Added an ability to encrypt disks without losing any information – all the information stored on the disk is encrypted.
Added an ability to create virtual encrypted disks based on file containers mounted as physical drives.
By default, encrypted disks have no signatures that can help determine that these disks were created by Cryptic Disk.
Added an ability to mount encrypted disks to empty folders on NTFS volumes.
To gain access to encrypted disks, users can now use passwords and key files.
The installer now has a new "Extract" mode that enables users to extract all program files for portable use (launching without installation).
The program can automatically play sounds files, launch programs or scripts (CMD Shell, Windows Scripts, PowerShell) upon mounting or unmounting of encrypted disks.
Added an ability to create hidden encrypted disks inside existing encrypted disks. The program supports several nesting levels for hidden encrypted disks: a hidden disk can be created as deep as three levels down.
When working with encrypted disks on multi-processor and multi-core platforms, the program driver uses all available cores for encryption, which gives a solid boost to the speed of encryption and decryption operations.
In addition to the AES (Rijndael) algorithms, the program now supports Serpent, Twofish, Blowfish and CAST6.
Added support of cascade encryption using several encryption algorithms. Users can now select the algorithms and their sequence. This capability makes it possible to increase the length of the encryption key to 2944 bits and dramatically improve the quality of data protection.
The new version of the program features a security mechanism against brute force attacks compliant with the PKCS #5 v2.0 specification. The user can select the algorithms used for obtaining the header encryption key: HMAC-SHA-512, HMAC-RIPEMD-256 or HMAC-Whirlpool.
The "CBC" data encryption mode has been replaced with "XTS", which was developed specifically for encrypting data on storage devices and drives all different types.
Added a virtual keyboard for protecting passwords from being intercepted by key loggers.
Improved support of dynamic volumes (software RAID arrays).
When unmounting an encrypted disk used by other programs, Cryptic Disk shows a corresponding notification with a list of these programs.
When mounting and unmounting encrypted disks, corresponding notifications are shown in the system panel.
You can now define individual hotkeys to each encrypted disk for its quick mounting and unmounting.
A backup copy of the drive’s header is stored at the end of each encrypted disk (can be used if the main header block at the beginning of the disk is damaged).
A new disk header import/export function has been implemented instead of the old encryption key export/import function (to/from a file).
Added full UAC ("User Account Control") support for Windows Vista and Windows 7.
Added a window with program usage tips.
Added a possibility to manually and automatically check for program updates on the program server.
Fixed a bug that occurred in the function responsible for automatically restoring the general access settings when mounting an encrypted disk.

v2.4 [Mar 10, 2008]
Plug-in are now supported. The SDK is distributed as open source together with the software distribution package. Now it is possible to configure the screensaver and protect it with a password. A lot of other fixes and improvements.
