First Step - User Profile and Logging On

Navaho Lock with Voice™ is used to send encrypted text, graphic and voice files over the Internet. Many of the features of this security program are designed to prevent unauthorized access to your files.

User Profile

When the program is first installed, no user accounts are set up. The New User Wizard will help you open a New User account so that you can create your Address Book and send or open encrypted files.

1.	Account Name

Enter your user name in the area provided. This will be the name assigned to your account and your Address Book.

2.	Full Name and Email

Enter your full name and email address in the areas provided. Recipients of your email messages will see this name associated with your messages.

3.	Phone Number

This section is optional. If you wish to have recipients call you to exchange passwords via telephone insert your phone number here. The phone number will be attached to your messages in an unencrypted state.

4.	Encryption Provider and Algorithm

To change the cryptographic service provider, select from the pull-down menu (either Microsoft&R& Base Cryptographic Provider or Microsoft Enhanced Cryptographic Provider). Please note if you send someone a message encrypted with an algorithm from the Enhanced Provider and they only have the Base Provider, they will be unable to open your message.

Once you have selected the cryptographic provider, a list of algorithms will appear in the Encryption Algorithm box below. Select the algorithm you want as your default.

5.	Password

Enter the password you will use to log on. Re-enter the password to verify it.

NOTE: This is the only password you need to remember to get into Navaho Lock with Voice  &TM& and send, receive and store files. *REMEMBER IT*.

Logon

Now that your account and password are set up, you can log on by either:

1.	Clicking on the Logon icon on the toolbar, or

2.	Clicking on the Actions menu, and then clicking on Logon.

Go to Step 2


Second Step - Creating your Voice Message

1.	You will require an external microphone to record a voice message. Make sure that it is properly connected to your computer before proceeding.

2.	Click the New button. The screen will then look like the image below.

Encryption Basics

Modern encryption takes advantage of the computer's ability to handle complex mathematics. All encryption schemes today use algorithms to scramble messages. Effective algorithms are extremely difficult to factor in reverse.

The two main types of encryption are public/private key (asymmetrical) and secret key (symmetrical). In public/private key encryption, a pair of keys is generated: the public key is used to encrypt the message and the private key is used to decrypt it. In secret key encryption, the same key is used for both encryption and decryption.

Navaho Lock with Voice ™ encrypts messages using secret key encryption.


Algorithm Basics

The algorithm is the mathematical formula that is used to scramble your data.  Algorithms work by shuffling blocks of data around, much like shuffling a deck of cards.  The "key" determines the sequence of shuffling and allows the data to be "unshuffled" back to its original order.

One of the main factors in the strength of the encryption is key size, which is measured in bits. Currently, 40-bit and even 56-bit keys are considered to be breakable, but 128-bit keys or higher are considered to be unbreakable with today's computers. Algorithms that use double, triple, or quadruple encryption will further stymie attempts to crack an encrypted message. These algorithms are used two, three or four times respectively (with a different key every time) to encrypt each message.

The Microsoft® Enhanced CSP comes with several strong encryption algorithms (up to 168 bits); however, current export laws in the U.S. limit messages to Europe and Asia to 56-bit encryption.

Cryptographic Service Providers


MS Cryptographic Service Providers

Navaho Lock with Voice ™ accesses the Cryptographic Service Provider (CSP) that is part of the Windows™ operating system (starting at Windows 95&TM&, release version 3). Most operating systems have the Microsoft Base Cryptographic Service Provider installed. To check your computer to see which cryptographic service provider is loaded, open the Address Book and select Add. Any installed cryptographic provider will show up in the drop-down menu. If you do not have a CSP installed, you can get it by downloading and installing Microsoft® Internet Explorer™ version 4.0 or higher.

The Base Cryptographic Provider is commonly used for communications outside of North America. The U.S. has strict laws controlling the export of strong encryption tools and it is quite possible your contacts in Europe and Asia will only have access to algorithms of 56 bits or less.  If you are unsure make sure you contact the recipient before sending an encrypted package using the enhanced CSP, otherwise they may not be able to open the package.

The Microsoft Enhanced CSP contains algorithms of up to 168-bit strength. If the Microsoft Enhanced CSP is not loaded on your computer and you are a resident in the United States or Canada you can download it by visiting http://www.microsoft.com/windows/ie/download/128bit/intro.htm.

Address Book Overview

The Address Book stores your contact names along with their email addresses and passwords. It is important to understand that a document associates with its Navaho Lock™ password like a key relates to its lock. Usually, a locksmith can replace or recreate a lost or damaged key. But a lost document password cannot be recreated, retrieved or substituted. Once the password is lost, all files stored with that password are essentially "lost".

The Address Book gives users the ability to create, modify and delete contacts. If you make a mistake in entering contact information or if you want to change a contact's email address or password, this feature proves helpful.

Read through the following sections to see how to use the Address Book and then go to Managing Your Address Book for file management strategies that will help you avoid access problems.

Import Addresses


Setting Up New Contacts

Open the Address Book and click the Add button.

Enter the contact information. A valid email address is required for each contact so that Navaho Lock with Voice ™ can function properly.

Choose a secret code for that contact.

Choose a cryptographic service provider and an algorithm.

Click OK to accept. Navaho Lock with Voice™ will prompt you to save the modifications to your Address Book.


Choosing Algorithms

As a general rule, the higher the bit number, the stronger the algorithm. Also some algorithms use double or triple encryption (e.g., DESX, Triple-DES). For a complete discussion of algorithms, open the Support tab in the Explorer window or visit the Navaho Lock with Voice support Web site directly at http://www.cypost.com/navaho/support.html.


Choosing a Contact Password

Navaho Lock with Voice ™ uses symmetric-key encryption, which relies on the use of the same password (secret key) by the sender and the recipient. The same contact password should be used for encrypting and decrypting a message. Obviously, you will need to agree on a password with your contact. You should decide this in person or over the phone. If you do not believe the phone line is secure, use a temporary password that is something you both know and that can be elicited by a hint (e.g., "Remember what you said to me in the elevator yesterday that made everyone laugh?").

The Address Book remembers these contact passwords for you. Since you only have to enter the password for each contact once, it can be complicated. A strong secret key includes numbers and both uppercase and lowercase letters.


Choosing a Cryptographic Service Provider

Most operating systems have the Microsoft® Base Cryptographic Service Provider installed. To check your computer to see which cryptographic service provider is loaded, open the Address Book and select Add. Any installed cryptographic provider will show up in the drop-down menu. If you need to download the Base Cryptographic Service Provider, go to Base Cryptographic Service Provider.

The Base Cryptographic Provider should be used for all communications outside of North America. The U.S. has strict laws controlling the export of strong encryption tools and it is quite likely that your contacts in Europe and Asia will only have access to algorithms of 56 bits or less.

The Microsoft Enhanced CSP contains algorithms of up to 168-bit strength. If the Microsoft Enhanced CSP is not loaded on your computer and you are a resident in the United States or Canada, see Enhanced Cryptographic Service Provider. Use this CSP for communications within North America only.


Deleting Contacts

If you delete a contact, you delete the associated password.

Any documents on your system that were encrypted with this password will therefore be inaccessible.

If you suspect that you may have files on your system encrypted with that contact password, you may want to double check the contents of the files before deleting the contact and the associated password.


Modifying Contacts

Modifying a contact can have the same problematic effect as deleting a contact.

If you change a contact's password, any documents encrypted with the old password will be inaccessible.

If you change a contact's email address, Navaho Lock with Voice ™ will not know which password is associated with any new documents received from that person.

The old contact password and address will open the older associated files, and the new contact password and address will open all future Navaho Lock packages.

Managing Your Address Book


Updating/Backing Up Address Book File

Creating backups is important - especially when you are dealing with encrypted files and passwords. When you first set yourself up as a new user, Navaho Lock with Voice ™ creates an Address Book with a filename that includes your user name and a .cya extension (username.cya). This Address Book file is stored in the Navaho Lock folder along with any other user's Address Book files. Navaho Lock encrypts your Address Book and all backups you make with your default algorithm and your password.

A simple backup strategy involves adding a 4-digit date in the format "mmyy" to the Address Book file name (i.e., username1299.cya). This will make it easy to select which backup is the most recent. You can also backup to a floppy disk for added security or when you need to use your contacts on someone else's copy of Navaho Lock with Voice.

Taking Navaho Lock with Voice ™ on the Road


Restoring from Backup

If for some reason you have inadvertently deleted a contact or modified a contact and you want to retrieve your last saved Address Book, choose Restore from Backup from the Address Book menu. A dialog box will open and you can then select your most recent backup. When you select OK, the contacts from the backup will overwrite the contacts in your current Address Book.

Any contacts that were in your original Address Book but not in your backup will be lost.

To keep these contacts, import the additional records to the backup Address Book before you perform the Restore from Backup. Go to Import Addresses for more.


Switch Address Book

This feature allows you to simultaneously maintain more than one Address Book file and to switch between them. If you want to use Navaho Lock with Voice ™ at home or on someone else's computer while you are on the road, you will need to bring your Address Book file and your password with you.

When you choose Switch Address Book from the Address Book menu, a dialog box opens that allows you to navigate to the Address Book you want to use. Select the Address Book file you want to switch to and press OK.

Navaho Lock with Voice™ will check the new Address Book against your user name and try your existing Logon password. If you have the same password for both Address Books, Navaho Lock with Voice™ will switch to the new one. If the new one is from a different user or has a different password, the program will prompt you for the correct password for the Address Book you want to switch to.


Import Addresses

The Import functions allow you to bring in contacts from one Address Book to another. This feature is useful when you have Address Books in more than one location, when you gather new contacts while on the road, or when you are using Navaho Lock with Voice ™ on someone else's computer. See Taking Navaho Lock with Voice ™ on the Road.

To import selected contacts, open Import Contacts under the Address Book menu. Navigate to the Address Book file that contains the addresses you wish to import. Open the Address Book using the password associated with that Address Book. Choose the address you want to import. To choose more than one, select the first address and hold down the Control key while selecting the other addresses you want to import. When all the addresses you want to import are selected, use the arrows to bring them over to the other Address Book and press OK.

To import from an Outlook Express Address Book, choose Import Address Book from Outlook Express under the Address Book menu. Select the contacts that you want to import from the list in the left window. Use the arrows to bring them over to be imported. Click OK.

You will then be returned to your original Address Book and the new addresses should be there. If there are any duplicates, Navaho Lock with Voice™ will ask you if you want to keep the existing ones or the new ones.


Managing Your Address Book

Navaho Lock with Voice ™ creates a new Address Book file, encrypted with a CSP and algorithm, whenever you set up a new user. More

The Address Book file, labeled with a filename that includes your user name and a .cya extension (username.cya), is stored in the Navaho Lock folder. As with any computer file, it is a good idea to back it up occasionally. You may already have a system for backing up files, but one approach is to add the date to the filename (i.e., username1299.cya).

As discussed in the Address Book Overview, access to documents can be lost if passwords and contacts are not managed properly.


Identifying Navaho Lock with Voice  Encrypted Files
Identifying Navaho Lock with Voice ™ Encrypted Files

Navaho Lock with Voice ™ encrypted files have a .nvl file extension. Locally filed documents default to the Navaho Lock folder in your program files.  Address Book files have a .cya extension. Address Books are also stored in the Navaho Lock folder.

Received files are stored within your email program, unless you resave them to the Saved Packages folder. More


Viewing Encrypted Attachments

When you open a Navaho Lock with Voice ™ package, the attachments are visible in the Drop area. You can view the contents of a file by double-clicking the filename. If you have an application that opens that kind of document, Navaho Lock with Voice ™ will launch the application and open the file.

If the file will not open, you either do not have the appropriate application or Navaho Lock with Voice™ cannot open the application. If you think you do have the appropriate application, you can drag the file out of the Drop area to another directory and try to open it using the application.

Be aware that once a file is dragged out of Navaho Lock with Voice™, it is no longer encrypted.


Retaining Encrypted State

By default, all documents in Navaho Lock with Voice ™ retain their encrypted state. You need to drag documents out of the Drop area to decrypt them or to save them in an unencrypted state.


File Will Not Open

When you double-click a document in the Drop area, the document will open with the appropriate application. If the document does not open, one of the following conditions may apply:

1.	You do not have the appropriate application installed for opening this kind of document.

2.	You have the application installed, but it is not recognizing the file extension. This can be changed in your operating system settings.

3.	Navaho Lock with Voice ™ cannot launch this particular application.

If you drag the file out of the Drop area into a folder in the Explorer view, you should be able to open it if you have the appropriate application.


Saving Outside of Navaho Lock with Voice
Saving Outside of Navaho Lock with Voice ™

If you want to save a document in an unencrypted state, simply drag it out of the Drop area into a folder in Navaho Explorer, or choose extract and it will be saved in an unencrypted state.


Starting a New Message

After logging on to Navaho Lock with Voice ™, press the New button or choose New from the File menu. A new Navaho Lock with Voice package will open - ready for you to record an encrypted voice message, type a text message and attach files for encrypting.


Finding and Moving Files for Encryption

The Explorer view to left of the Drop area is where you can navigate through your files to find the ones you want to encrypt. Find the directory or folder that contains the file you are looking for and double-click on it. The contents of the directory or folder will be displayed in the lower window. You can select the file you want and drag it to the Drop area for encryption.


Using the Message Area

You can type or paste any text message into the Message Area. The formatting tools below allow you to add color, change fonts and appearance, and justify text.

Use the tabs at the bottom of the Message Area to enter encrypted text and/or exposed (unencrypted) text. Select the Encrypted Message Area tab to enter the portion of your message that you want protected. Select the Non-encrypted Text Area tab to enter the text that you want exposed.


Using the Voice Area

You can record, delete or playback a Navaho Lock with Voice ™ encrypted voice message using the features of the Voice Area.

To record an encrypted voice message with Navaho Lock with Voice, click on the Record button (plus sign) in the Voice Area and a dialog box will prepare your message.

To delete an encrypted voice message, select the voice file in the Voice Subject header window and click the Delete button (minus sign).

To play an encrypted voice message, select the voice file in the Voice Subject header window and click the Playback button (triangle). To stop the voice message, simply click the Stop button (square).

When you send a Navaho Lock with Voice package, any attached voice file will automatically be compressed and encrypted. If you want to send the voice message unencrypted, you will have to send the entire package as an unencrypted transmission.

Sending Unencrypted Messages


Sending the Encrypted Message

When your Navaho Lock with Voice ™ package is ready to send, press the To button in the Message Area. The Address Book will open so that you may choose a contact to send the message to. After you select a contact and press OK, Navaho Lock with Voice will return you to the main screen.

Press the Send button in the Message Area and your message is sent. More


Sending to Non-Navaho Lock with Voice  Recipients
Sending to Non-Navaho Lock with Voice ™ Recipients

You can safely send a Navaho Lock with Voice ™ encrypted document to a non-Navaho Lock user. When the person receives the email, they will see a message telling them that the email was encrypted using Navaho Lock with Voice™ and download instructions.


Save Overview

Pressing the Save button drops down a menu of choices that will be applied to the currently open document:

Save	Saves changes to a previously saved package in the same location and with the same filename. If you have not previously saved a version of the package, the Save As dialog box opens.
Save As	Opens dialog box to allow user to choose name and location for encrypted package
Save to Saved Packages Folder	Shortcut to save an encrypted package to Saved Packages folder in Navaho Lock with Voice ™

Encrypting Files on your Hard Drive

Saving before Logging Off


Saving Encrypted Copies of Outgoing Mail

Navaho Lock with Voice™ automatically saves sent mail in a folder called Sent Packages in the Navaho Lock with Voice™ folder. You can view this folder under the Sent Packages tab in the Explorer view.


Saving Encrypted Copies of Incoming Mail

Incoming Navaho Lock with Voice ™ packages are stored within your email program. You can either leave them there or save them to a different location

Choose Save if you have made changes and want to save the package to the same location.

Choose Save As to save the package to a location of your choice.

Choose Save to Saved Packages to save the files to the Saved Packages folder.

After saving an encrypted copy of incoming mail, you can delete the original email and any associated attachments.


Saving Unencrypted

You can save any encrypted file attachment in an unencrypted state. Simply drag the file out of the Drop area into a directory in the Navaho Explorer view. To save the text message in the Message Area, copy and paste it into a word processing document and save it in the same directory as the attachments.


Encrypting Files on your Hard Drive

Drag the files that you want to encrypt to the Drop area. Press the Save button and select Save, Save As, or Save to Saved Packages.


Saving before Logging Off

If you have minimized messages open in Navaho Lock with Voice ™ and you leave your workstation, the session may timeout. You will have to log on again to make any changes to these files or to save them. If the files are in a saved state, you can simply choose Exit from the File menu to quit the application. If you have not saved the file yet, quitting will bring up a Save dialog box. You may need to log on again to save the file.

To change the timeout setting, see Logging Off and Timeouts.

If a user leaves files open and unsaved and a second user wants to quit the Navaho Lock with Voice™ program for them, they will have to quit the application without saving the most recent changes to the files. The second user must say "No" to the query "Do you want to Save changes to …?". Navaho Lock with Voice™ will quit without saving the most recent changes to the affected documents.


Managing File Overview

Your file management requirements will vary depending on how and where you use the Navaho Lock with Voice ™ application.

If you are the only person who uses Navaho Lock with Voice™ on your computer and it is the only computer you use it on, file management will not require any special considerations.

If you use Navaho Lock with Voice™ both at work and at home, or have multiple users, it will quickly become difficult to know which file belongs to what user unless some organization is done at the outset. For multiple users, it is highly advisable to create individual directories for storing each user's encrypted files.

Closing Open Files

Closing Other User's Files

File Names

Setting Up User Directories


Closing Open Files

When you close a Navaho Lock with Voice ™ file after viewing it, it automatically returns to its encrypted state. You must use Save As under the Save button to store it in an unencrypted state.

If you leave your workstation when you are logged on to Navaho Lock with Voice™ and you are not in High Security Mode, any casual passerby can peruse an open file. It is recommended to close files and logoff when you leave your workstation.

When you quit Navaho Lock with Voice™, the program will prompt you to save any unsaved documents. Saved documents will close without bringing up a dialog box.

Logging Off and Timeouts


Closing Other User's Files

If another user leaves and fails to close their open files, you can close them by exiting the Navaho Lock with Voice ™ program. If their work has any unsaved changes, the program will prompt the user to log back on.

If that person has left the premises, you can choose to quit without saving, or leave the Navaho Lock with Voice™ program running until that user returns and can log on again.


File Names

For security purposes, your file naming scheme should mean something to you - but nothing to unauthorized individuals. A filename like "passwords.nvl" would more likely be a target of attack than "whitewall.nvl".


Setting Up User Directories

You can create directories within the Navaho Lock with Voice ™ folder or in a file area of your choice. If you have a lot of contacts or expect to receive a lot of encrypted mail, creating directories will make finding files much easier.

If several people use one Navaho Lock with Voice™ program, it is a good idea to create individual user directories and any sub-directories necessary to manage the files. Each user can store their encrypted files within their own directory.

You might even want to create a text file directory of your encrypted files (add each new file to the directory as you receive it and encrypt the directory file under your password).

Encrypted Directory Listing


Address Book Contact Passwords

Contact passwords and secret keys do not need to be remembered by either party, since the Navaho Lock with Voice ™ Address Book remembers them for you. Combinations of at least 8 characters (longer if you can remember it), including both uppercase and lowercase letters and numbers, will provide the strongest protection.

For added security, use one password for files you send to a correspondent and another for files you receive from that correspondent.


Directory Padding

Since it is a major undertaking to break an encrypted file, encrypt some unimportant files (e.g., a picture of your dog, a long joke, or a Readme file) and place them in your encrypted files directory. There's a good chance that anyone trying to break into your files will hack a bogus file - an effort that will waste their time and protect your interests.


Encrypted Directory Listing

Once you begin to amass a large quantity of encrypted files, you may have difficulty remembering what was in any particular file. In this case, make up a directory listing that will remind you of file contents without being too specific. Encrypt, name and store that directory file with your other encrypted files.


File Naming

If you name a file "finance.nvl" or "accountinfo.nvl", they will most likely be singled out for attack. Instead, make up "pet names" for your files based on something you can easily associate with the particular file. Create a file naming convention that means something to you.

If you have difficulty remembering file contents, create an Encrypted Directory Listing.


Nested Encryption

Cryptanalysts debate whether encrypting and then re-encrypting documents will make the files harder to break. In some instances, such as double encryption using the same password, the resulting encrypted file can actually be weaker than a file treated with single encryption.

If you want to try re-encrypting an encrypted file, you might try one of these techniques (although we do not advocate that either of these tactics will increase security):

1.	Place your encrypted file into a folder with several other files and then encrypt the whole folder.

2.	Use a different algorithm and password for each subsequent encryption.


Storing Off System

In case of fire or theft, sensitive files or those that cannot be duplicated or resurrected should be stored in a safe place off your system. It is recommended that you keep a backup copy of your Address Book file off the system as well.


User Passwords

Your user password, or Logon password, is the only password you need to remember to access all of your encrypted documents, your Address Book, and the passwords for all of your contacts. It is vitally important that you remember it, rather than writing it down. A password that is short or easy to guess weakens your security.

Smart hackers realize that people tend to use passwords that are easy to remember. Rather than trying brute force attacks, they will research their victim's birth date, hometown, high school, pet's names, etc., and then try different permutations of these words and numbers.

A strong password contains at least 8 characters (longer if you can remember it), including both uppercase and lowercase letters and numbers.

If you forget your password, you will lose access to all of your encrypted documents and you will have to set yourself up with a new user identity.

Algorithms

The algorithm is the mathematical formula that is used to scramble your data.

Algorithms work by shuffling blocks of data around, much like shuffling a deck of cards.

The "key" determines the sequence of shuffling and allows the data to be "unshuffled" back to its original order.

One of the main factors in the strength of the encryption is key size, which is measured in bits. Currently, 40-bit and even 56-bit keys are considered to be breakable, but 128-bit keys or higher are considered to be unbreakable with today's computers. Algorithms that use double, triple, or quadruple encryption will further stymie attempts to crack an encrypted message. These algorithms are used two, three or four times respectively (with a different key every time) to encrypt each message.

The Microsoft® Enhanced CSP comes with several strong encryption algorithms (up to 168 bits); however, current export laws in the U.S. limit messages to Europe and Asia to 56-bit encryption.
