CAt this point you may set a default password for encryption. This is useful if you want to encrypt several groups of files with the same password. If a session password is set you don't have to enter the password for each encryption, instead Dircrypt will use the sessionpassword. A sessionpassword is only valid for the current run of dircrypt, if you exit Dircrypt the sessionpassword will not be saved. In addition the sessionpassword is only functional for encryption, not for decryption. You can deactive a sessionpassword by choosing the menuitem "Delete sessionpassword".

Dircrypt is a safe and very fast way to protect your data against unauthorized access. Dircrypt will hide your data from anyone without the correct password. Dircrypt needs less than 5 seconds to protect 40 MB on a harddisk, or 5 seconds to protect a whole 1,44 MB floppydisk. Dircrypt is able to work on single file and on directories and subdirectories. π
DIRCRYPT protects access to files and directories by deleting their directory entries and marking their clusters as bad in the FAT table. That means if you use CHKDSK or another disk utility on a disk with protected data, they will report bad sectors on this disk. This sectors will disappear if you decrypt the disk again. It won't matter if there have already been real bad sectors on the disk, Dircrypt is able to differentiate between its own simulated bad sectors and real ones. The deletion of the directory entries is done in a way which makes it impossible even for the professional to restore them, for example with UNDELETE or other utilities. The directory entries are deleted completely and there is no way to even get to know their names. By the way, when I am talking about disks, I mean floppy disks, harddisks or harddisk partitions. Compressed disks like Double Space or Stacker are supported only partially, please read DIRCRYPT.DOC before using Dircrypt on compressed disks. q
To encrypt files or directories on a disk, first select the desired drive ( hit F2 ), then select Encrypt disk.

You are only allowed to use the shareware version of Dircrypt in order to check if Dircrypt fits your needs. If you want to use Dircrypt you are required to register (i.e. buy the program). Further information on shareware can be found at the help topic Shareware ∙
This menu item lets you fill out the register form for ordering the registered version of Dircrypt which has no annoying shareware screens. After you have filled out the form you may print it out or save it to an ASCII textfile for later printout. ║

You can change between the two listboxes by using cursor left and cursor right. When in the right listbox you can unselect files by pressing space, and you can toggle encryption level by hitting "M". Encryption level 2 is a lot slower than normal encryption, so just use it when really neccessary. You will find further information on when to use level 2 in DIRCRYPT.DOC. You can change encryption level for all files at once be pressing Alt-M. ▄

Select the button "Masterpassword" to setup a masterpassword. This password serves three purposes: first it protects the current dialog window, so unauthorized users can not make any changes to the settings, second it serves as a programpassword, if the option "programpassword" is activated, and third it can be used for decrypting files which have been encrypted with the option "masterpassword" activated. ╗
The option "masterpassword active" serves as a backdoor for decrypting files without knowing the used password. If this files have been encrypted with the option set the masterpassword can be used for decryption by choosing the menu item "Drive/Master-decrypt". This feature is especially usefull if you want other persons to be able to protect their data from each other on your pc, but you want complete access to all data in case of need. ÿ
The option "programpassword active" is for protecting the execution of Dircrypt itself. If activated the right password must be supplied at startup of Dircrypt, otherwise Dircrypt will not work. This way no one can even try to use Dircrypt if he does not know the programpassword. To set the programpassword press the button "programmpassword". Please note that apart from the programpassword the masterpassword can also be used to get access to dircrypt. Use the masterpassword if you want access to this dialog and to the menu item "master-decryption". If you log in with the programpassword and not with the masterpassword you have no access to this features. v
If you activate the option "programpassword as only password" Dircrypt will always use the programpassword for encryption and decryption. This is useful if you are always using the same password, this way you just have to supply the password at program startup, and afterwards Dircrypt will automatically use this password and not ask before each encryption or decryption.

 Datafile duplicate save
 ───────────────────────
▀
DIRCRYPT saves information about an encryption in a file named DCDATA*.DAT. This file is needed for decryption, without this file decryption is impossible. This file is made writeprotected and hidden to prevent it from being deleted by mistake. But it is still possible to delete the file, for example with certain filemanagers. If you think the DCDATA*.DAT file may get deleted by mistake you can activate this option. In response Dircrypt will make a copy of the datafile when encryption. This copy is not a file, but it is placed sectors marked as bad, so it can not be deleted or destroyed unintentionally. If the first DCDATA-file is lost, Dircrypt is able to reconstruct the file using this copy. For this choose the menu item "Rebuild datafile". There is a drawback when activating duplicate save: the diskspace needed for the datafile is doubled because of the copy, and encryption may take (insignificant) more time. You may only recover a datafile if you know the right password.

Use this to protect Dircrypt against power blackout or switching off the PC by mistake. If activated you can restart Dircrypt and Dircrypt will continue the interrupted encryption or decryption. Progress-log can only be used when encryption or decryption is not taking place on the same drive where DIRCRYPT.EXE resides. Major drawback: encryption and decryption will be noticable slower. Note that this option is not a guarenteed protection against loss of data when the computer is switched of during operation of Dircrypt. So MAKE BACKUPS to be on the safe side. By the way, I myself don't use this option because I want real fast encryption and decryption, and I have backups.

Use the "search" buttons for easy selection of filenames and directories. ─
After all input has been made select "Ok". Dircrypt will ask you for the files and directories you want to encrypt, encrypt them and create the new loader executable.
