Adding a file to an archive

To add a file or files to a pre existing archive file , select the proper drive and directory containing the archive file and either double click on the archive file in the file list box or select the file using the keyboard an hit the return key while the file is selected or go to the archive menu and select the view command. The contents of the archive file will then be displayed in the archive list box. The archive listbox will show the names and sizes of all files stored in the archive. To add files to the archive change to the drive and directory so that the required files are shown in the file list box , next select the files to add to the archive file using the mouse and shift/ctrl keys, once you have selected the desired files , select the Add to archive option from the archive menu or simply drag the files from the file list box  (by clicking the mouse on any of the selected files and moving the mouse while holding down the left mouse button) and drop the files over the archive file list box. The files will then be added to the archive and the archive list will be updated and will show the new files that have been added to the archive. If no archive file is selected in the archive file list, the single or multiple file compress dialogs will be shown permitting you to create a new single or multi file archive for the files that you wish to compress.


Archive List

The archive list displays the contents of the currently selected archive file, including the filenames, full and compressed file sizes. To select an archive file double click or press the enter key on the desired file in the file list box , It is possible to expand files by dragging the files form the archive list and releasing in the directory list box or file list box. To add files to the archive ,select the desired files in the file list box and drag the desired files from the file list box and release them  in the archive list. You may clear the contents of the archive by selecting the clear archive function in the windows menu or by clicking on the clear archive button on the speed bar.


Attach Files

Attachments are files which have been included in a mail message. The files you select will be included in the mail message you send and should be converted to files by the recipients mail software.

To change directory double click on the selected directory, to expand and collapse directory trees click on the previous or highest directory in the display.

It is possible to drag files from the file list box and hence move or copy the files, you may also drag and drop files from the archive list box and in doing so expand the files to the desired location. In both cases the target directory is displayed on the status bar at the bottom of the screen.


Display window

This is used to display mail messages. Upon downloading mail you may view the messages and save

them by viewing the messages. if you do not view the messages they will be lost. Attached files will be

separated from the mail message upon viewing.

The main options in the display window are:-

 Save file 	:Saves the current mail message.

To change the current drive simply click on the down arrow in the directory selection option and then click on the desired drive letter. The directory list box will then show the contents of the select drive and the file listbox will be updated with new information.


Encrypt
Encrypts selected files.


Encrypting files

Encrypting files uses a key as a starting point which gives billions of possible combinations of values which can be used, thus making it unlikely that anyone will guess the combination to your file, hence keeping it secure. When a file is encrypted it's values are changed making it meaningless to anyone trying to see the contents of the file. The main encryption options are :-

Single file encryption

Multiple file encryption

Encryption level options


Encryption level

There are three main levels of encryption - low, medium and high, The main difference that the user will see between the encryption levels is the time taken to encrypt the files, if you are using an older machine then you may find that it takes too long to encrypt a file using the higher encryption levels and you may feel that it is better to sacrifice some security for time and use the lower encryption level, Users of relatively modern machines will notice very little time difference between the encryption levels and are advised to use the high level constantly. Files will have added protection if the high level encryption is used, along with your password and keyword. The encryption method used is based on DES, The

current key size is 80bit, this will be change to 96bit in the near future and a 160bit key for safedrive.

For each segment of the key you may assign values form A..Z and 0..9 this gives approximately 50bits of

possible key values.


Encryption level options

There are three encryption levels which can be used, these are

low

medium

high

The time difference between low level encryption and high level encryption is minimal for modern machines as the rate of encryption is limited mostly by disk access speeds and not processor power, although this may not hold true for older machines.

When encrypting files the encryption level is contained within the encrypted file. This method is slightly less secure than excluding the information, but it means that the user does not need to remember the encryption level that was used to encrypt the file to decrypt it. earlier versions of this software included no encryption information in the encrypted file and hence were slightly more secure, but a bugger to use if your memory wasn't too hot.


Environment options

There are several categories in the general environment options, these are :-

File display options

Keyword

Password

Settings


Erase original file

This option is available in the encryption, decryption, compression and extraction dialogs, you may also select it to be checked by default in the setting dialog. when checked the erase original files erases files once they have been operated on, Use wisely.


Exit
 Closes Ncrypt.


Expand menu option
Expands selected compressed files.


Expanding Files

Expanding files decompresses compressed files and separates archive files from the archive. You may expand all the files in an archive or expand only selected files from within an archive file to expand. It is also possible to select multiple archive files to expand in a single operation.

Expanding a single file

Expanding multiple files


Expanding a file from an archive

To expand a file from an archive use the drive selection and directory list box controls to move to the directory which contains the desired archive file. Once the archive file is displayed in the file list box.either double click on the archive file or select the file using the keyboard an press the enter key or select the view command from the archive menu. The contents of the archive file will then be displayed in the archive list box. select the file or files that you wish to extract from the archive and then drag them to either a directory in the directory list box (the target directory is shown on the status bar) or the file list box to extract them to the current directory or select the Extract from archive menu option in the Archive menu. If you wish to extract all the files within the archive you should select the archive in the file list box and then click  on the decompress button on the speed bar or select the decompress option in the windows menu.


Expanding single/multiple file(s)
Expanding single/multiple files

To expand single\multiple file(s) Select the file(s) to be expanded in the file list then select the expand option from the File Menu or click on the expand button on the Speed Bar. The expand dialogue will then be shown. An option to erase original file(s) is available and the target directory for the expanded file can be set.  If you select a directory that does not exist you will be given the option to create the desired path.  Once you are certain that all settings are correct, select the OK button to proceed. The files will then be extracted to the desired location. It is possible to drag and expand selected files from within an archive or expand multiple archives in a single operation.


File display options
File display options are available in the settings windows, these control the types of file listed in the file list display, i.e. read only, hidden, system, archive.


File list

The file list is located on the right hand side of the window, it contains a listing of the files that are contained in the currently selected directory. It is possible to move or copy files form the file list to another directory by selecting the desired files and then dragging them to the desired directory in the directory list box , by selecting the file copy or move options in the file menu, or by clicking on the file move/copy icons in the speed bar.

To select a file use the mouse and click on the desired file, to select additional files use the ctrl key and click on the next file with the mouse, another option to select a group of consecutive files is to click on the first file then hold the shift key and click on the last file.

It is also possible to drag the files and release them in the archive list box, the files will then be added to the currently selected archive file, if there is no active archive file selected you will be given the option to create a new archive.


File list filter

The file list filter is located beneath the speed bar above the file list box.

The filter controls the files that are displayed in the file list box. The filter uses dos type wild cards ie * for anything.  e.g.

*.*	 	Displays all files.

*.pak	Will only display files with the pak extension

new.* 	will only display files called new but will ignore the extension

s*.* 	Will show all files beginning with the letter s.

You can use the filter to selectively show desired files.


General file controls

There are several option that you can use to manipulate files.

Copying a file

Initialization file

The initialization file cryp.ini is located in the windows directory, it contains various initialization information required by ncrypt. Do not delete, move or attempt to alter the initialization file or ncrypt will not start and it will be necessary to reinstall ncrypt. The Ini file is encrypted by ncrypt in a two stage process.


Key
Select Key to enter your own Keyword. If no keyword is set then Ncrypt will automatically use DEFAULTKEY for the keyword.

Note: Keyword must be Ten characters long.


Keyword

The keyword is used as a starting point for any encryption routine, it provides the starting point for ciphering and deciphering. To set the keyword click on the keyword button on the speed bar or select the keyword option from the windows menu. The key dialog will then be shown , it will display your present keyword value and provides the option to change the keyword value. If you have not set the keyword then the key will have the default value of DEFAULTKEY . You may enable the option in the settings dialog to retain last key so that the last used keyword will be used when ncrypt is restarted after shutdown. The keyword consists of characters in the range A..Z and 0..9 no other characters will be accepted. The mail keyword is unrelated to the File Keyword and may be up to 256 characters long.

N.B.

The keyword must contain Ten letters. This provides a key of 80bits,this will soon be changed to a key

of 96 bit.

You must use the same key to encrypt and decrypt a file.


Low Encryption
Determines level of encryption.


Mail

You can use ncrypt to send and relieve encrypted mail. Encrypting your email means that the contents of your message is secure and can only be read when it has been decrypted using the proper mail keyword. Using this method you may send and receive mail knowing that the contents cannot be read by any unauthorized persons.

N.B. Attached files are not encrypted and should be encrypted using the file encryption

facilities in Ncrypt.

Sending Mail

Receiving Mail


Mail encryption key

The mail encryption key Can be set from the send mail and get mail windows. The key can consist of up to 256 characters of any value. If no key is set the value will be DEFAULTKEY. The key is used to determine how the mail message is encrypted, once you have encrypted a message you will not be able to alter the message. to edit the message you must first decrypt it. Files sent as attachments are not encrypted , to encrypt these files you should use the file encryption features included in Ncrypt.

IMPORTANT

The same key value must be used to encrypt and decrypt mail messages.


Mail parameters

The following fields must be set correctly before using the send mail facility.

SMTP Server 	:Usually something like Mail.Servername.co.country

i.e. if your internet providers name was provider.com

then your mail server address would probably look

something like  mail.provider.co or mailhost.provider.co

Email Address 	:This is your email address, normally your log on name followed

by the @ symbol and then your servers name ie if you name were

Problems

There are certain circumstances where you may be unable to perform operations on files. In the majority of cases this will be due to files having the same file name and existing in the same directory.

E.G.

If you add a file to an archive and a file with the same file name already exists in the archive the previously existing file will be replaced with the new file.

If you include a file in an archive and it has the same file name as the archive then you will be unable to extract the file to the same directory as the archive file.

If you use a default file extension with multiple files ,eg enc to encrypted files and one of the files has the same file extension eg  trying to encrypt thefile.enc to the file.enc will not work unless you use the keep original filename option.

If you encrypt files with compression using the keep original filename option and then decrypt the files with the keep original filename option you will be unable to expand the compressed files in the same directory as they will have the same file name as the compressed file.

Do not use the default extension option when files have the same name eg

if you attempt to compress thefile.wpd ,thefile.pas and thefile.doc you will only be able to compress one of the files as they will all have the same filename and exist in the same directory.

You may also receive errors when operating on files if you have selected multiple files and any of the output files has the same name as one of the input files and you select the replace file dialog when prompted.

Please do not use the erase original files option until you have some experience using ncrypt. The functionality of this software can be time saving when used properly , but can also be bothersome when used in ignorance.

Wipe Delete

When you normally delete a file the system removes the first character of the filename in the F.A.T. (File Allocation Table), Doing so marks the file as deleted by the system and tells it that the disk space previously occupied by the file can now be used. The file is not actually removed from the disk until it is overwritten, which normally occurs several days later, when a new file is allocated the disk space previously used by the file. By using the wipe delete function the file is overwritten during the deletion process ensuring that the files contents cannot be retrieved using any file undelete program.
