First bytes of BestCrypt encrypted file-containers contain information about size of the container, two signatures (LOCOS94 and CRYPTED_DSK), identificator of encryption algorithm, etc.
Existence of the information in opened form may be helpful. Size characteristics of container in its header allows BestCrypt Control Panel to discover damaged container when it initially reads files in root directory of every drive. Besides, in case of damaging hard drive or file system the container file can also be damaged as any other regular file on the drive. In that case opened signatures may help the user to find start bytes of the file and possibility of restoring a whole container file increases considerably.
From the other hand, existence of signatures makes BestCrypt container files recognizable as encrypted data files. BestCrypt v8+ provides an opportunity for users to choose whether they want to encrypt the header of container to get the file looking as a file completely filled in by random data, so that it is impossible to prove that the file contains encrypted data. However, you should realize that files with random data may not confuse skillful investigators of your computer and they will still suspect that the large amount of random data on your disk is encrypted data.
To encrypt header of container file, you should do the following:
NOTE: 1. Containers with encrypted headers are not shown in BestCrypt Control Panel.
To work with such containers, you have to use Browse
command from menu.
2. Containers with encrypted headers are not guarded by Container Guard Utility.
