NS Secrets is a security utility which allows you to encrypt documents, applications and also other datatypes, like E-Mail or the Clipboard. It uses the advanced Dyna64 encryption scheme, developed by the NEWTECH Research Center in Luxembourg, and offers PGP-like security but with much more speed. NS Secrets offers a lot more of features, like drag and drop, FingerPrints, data compression, ... . It simply has high security and great speed to a low price.
NS Secrets is Shareware. If you want to use it without restrictions please pay the 10$ Shareware fee.
System Requirements
NS Secrets should work on any Color Macintosh with at least 2048 Kb free RAM and System 7.0 or later.
The File Menu
NS Secrets is rather simple to use, so you should not encounter any difficulties due to the user interface.
Encrypt... and Decrypt... show a standard open dialog, where you may select a file or an application you want to encrypt/decrypt.
After having selected Open, you will be asked a password which you'll have to enter twice.
If both passwords are the same, a status dialog will be shown while NS Secrets is encrypting/decrypting.
Notes: -The password is not stored within the encrypted file. So if during decryption, you twice enter a wrong password, your data will be lost! Take care to remember the right password!
-Your password should always be shorter than the data to encrypt! So if your data presents only 8 characters, your password must be smaller than 8 characters. (But this case should be very rare)
-The longer the password is, the better the Dyna64 code will work. (It does not take more time to encrypt with a long password than with a short password)
Register ... This menu item shows up a dialog with the serial number of your copy of NS Secrets. To register, send 10$ (or the equivalent in your currency) by cash or by Eurocheque with your Last Name, First Name, Company Name, your complete address, your E-Mail address (if available) and the version and Serial Number of NS Secrets to me (address below).
I'll return you your registration code which you'll have to enter after clicking onto Register now ... in the Register dialog. After having registered you'll be able to enjoy a full version of NS Secrets.
Quit Lets you quit the application. (What else?)
The Edit Menu
Encrypt Clipboard and Decrypt Clipboard let you crypt or decrypt the content of the clipboard. This may be very useful for E-Mail and similiar data. You will be asked a password, exactly as with the Encrypt or Decrypt function in the File menu.
Show Clipboard displays the content of the clipboard and optionally lets you encrypt/decrypt or delete the clipboard.
The FingerPrint Menu
What is a FingerPrint?
A FingerPrint is a digital code which allows each owner of NS Secrets to identify the sender of the files he'll decrypt. It's composed of two 8 digit lines.
Create FingerPrint... This item lets you create your personal FingerPrint. It will be stored in the FingerPrints file, in the same folder as NS Secrets. After this step, you may include your FingerPrint in your encrypted files and the receiver of the files will be able to identify you as the sender (if your FingerPrint already is in his database).
Note: Once you've created your personal FingerPrint, you should not change it. Store a copy of the FingerPrints file on a save disk (i.e. a Floppy disk).
Copy FP to Clipboard copys your personal FingerPrint into the clipboard. It'll look like:
NS Secrets
15472589
14523025
FingerPrint
Show FingerPrints displays a list of all the FingerPrints saved in the FingerPrints file. You may add a Fingerprint to the database when receiving a file with an unknown FingerPrint or by one of the Personal FingerPrint applications created with the FingerPrint Maker application.
You may also remove FingerPrints from the database(but not the MasterPrint, your personal FingerPrint).
The Options Menu
Crypt datafork only If checked, only the datafork of the files will be encrypted. This may be useful for encrypting E-Mail, images or plain text files.
Compress files If checked, all the encrypted files will be compressed, saving about 50% of their original size. Unfortunately the compression code is not yet stable enough for a public release, so it doesn't work yet. Sorry!
Include FingerPrint If checked, your personal FingerPrint will be included in all your encrypted files. If you want to stay anonymous, this option should be deselected.
Show Sender's FP If checked, NS Secrets will display the FingerPrint of the file's sender for each file. You'll see the complete FingerPrint and , if in the database, also the real name of the sender.
Save options Saves the options as selected above.
Note: -Your FingerPrint may only be included in files. So it may not be included when encrypting the clipboard.
-When using drag and drop, NS Secrets will use the saved options.
-Only registered users may save their options. So if using drag and drop with the Shareware version of NS Secrets, default options will be used.
-If the Crypt datafork only option was selected when encrypting a file, it must also be activated when decrypting the same file or you may experience data loss.
About the FingerPrint Maker application
The FingerPrint Maker application, once started, transforms itself into your personal digital visit card. It'll include your personal FingerPrint, your full name and you may add up to 256 characters of personal information (address, e-mail, homepage,...). You may then distribute this application along with your encrypted files. The receiver may then add your FingerPrint and real name to his database by clicking onto Save in FP file in your personal FingerPrint application.
Note: As the FingerPrint Maker application transforms itself and therefore will be erased, it will certainly be suitable to use a copy of the application instead of the original.
About the Dyna64 encryption scheme
Developed by the NEWTECH Research Center in 1996, Dyna64 is one of the most powerfull encryption schemes that exist. It uses a 64bit dynamic code. That means that the data is encrypted using a 64bit code which does change dynamically while a hacker or any other person try to break the code without the right password. NS Secrets is the first public encryption program using the Dyna64 encryption scheme.
Currently NEWTECH Research are developing an even more secure code, the TriDyna64 code. This code replaces all characters by digits between 0 and 9 and then compresses the file to obtain a file size similar or smaller than the original file size. After release, this encryption scheme will most probably be the most secure in the whole world. And it will be available in one of the next releases of NS Secrets !!!
Further informations
NS Secrets does support drag and drop. You may drag a file or a group of files (but no folders or disks) onto NS Secrets. They will be encrypted/decrypted using the saved options.
Until you become a registered user, you will get a message at Startup, you won't be able to save the options and after 30 days, the demo will have expired. You may then still decrypt files, but no more crypt them.
