Useage: MakeKey( nKey, nLicense )

        nKey is your "secret key"
        nLicense is the number of licenses the end user has purchased
                 this is a number that can be extracted by GetLicense()

        Example: We will use 581 as our "secret key"
                 We will give the end user 5 licenses

                 cKey := MakeKey( 581, 5 )

                 If the Hard Drive Serial Number is: 123456789

                 cKey will be: 986-3266501-3064-26145
 
                 cKey is the number you give the end user to "unlock"
                 your software.


Useage: MakeKey()

        If you use MakeKey() without any parameters you will be prompted
        to enter nKey, Hard Drive Serial Number and nLicense.
        The the cKey will be displayed via MsgInfo()

        The "Hard Drive Serial Number", "Generated Key" and "Number of Licenses" will also
        be copied into the Clipboard.
  


Useage: GetLicense( nKey, cKey )

        nKey is the "Secret Key" you used in MakeKey()
        cKey is the string returned by MakeKey()

        Example: We will use 581 as our "secret key"
                 cKey will be: 986-3266501-3064-26145 (see example above)                      

                 nLicense := GetLicense(581, "986-3266501-3064-26145" )

                 This will determine the Hard Drive Serial Number and using
                 the parameters provided, will return the number of licenses
                 that were encoded when you used MakeKey()

                 So, if the Hard Drive Serial Number is 123456789
                 nKey is 581 and
                 cKey is  986-3266501-3064-26145

                 nLicense = 5



Useage: VerifyKey( nKey, cKey)

        nKey is the "Secret Key" you used in MakeKey()
        cKey is the string returned by MakeKey()

        Example: We will use 581 as our "secret key"
                 cKey will be: 986-3266501-3064-26145 (see example above)                      

                 IF VerifyKey( 581, "986-3266501-3064-26145" )
                    MsgInfo("Valid Key...")
                 ELSE
                    MsgInfo("Invalid Key...")
                 ENDIF



Useage: GetSecretKey( nSerial, cKey )
             
         WARNING: Run this function without other programs running.  It uses as much of the
                          CPU as it can and depending on your "Secret Key" may take a LONG TIME to
                          complete its calculations before you are given your "Secret Key"
                          (it is slow, but atleast you now can get your "Secret Key" if you forget it)

         nSerial is the serial number used to make cKey
         cKey is the string returned by MakeKey() 

         Example: 
                    nSerial = 123456789
                    cKey = 986-3266501-3064-26145 (see example above)                      

                    cSecret := GetSecretKey( 123456789, "986-3266501-3064-26145" )

                    cSecret wil be 581


NOTES: 1. The value returned by MakeKey() should be stored on the end users
                 system and a check [ VerifyKey() ] should be done to determine if
                 the user has a valid installation.

             2. If you need to change the amount of licenses, you will need to
                 generate a new Key. [ MakeKey() ]

             3. This library only gives you "a number" for licenses, it will not
                 limit the end user ... This is left up to you, the programmer.
                 So the value returned from GetLicense() should be used to limit
                 connections to the program. (This is mainly for networked systems)
                 If you are not worried about licenses then you can use this as a
                 secondary "Secret Key", however you MUST supply a value.

              4. The only function that can be used without any parameters is
                  MakeKey(), you MUST supply the parameters for the other functions.

              5. The "Secret Key" must not be zero, this may cause problems.
