PKS Version 1.0

     Public  Key  System routines are derived from  the  article; 
'Public  Key Cryptography:  An Introduction to a powerful crypto-
graphic system for use on microcomputers" by John Smith found  in 
BYTE magazine Volume 8, Number 1, January, 1983.

     The  routines here are MBASIC compatible and differ from the 
published  routines only in handling of the BASIC  function  RND.  
MBASIC  RND  with  an argument of zero  simply  returns  whatever 
number was last generated.   The MBASIC command RANDOMIZE is used 
to seed the random number generator with a number from 0 to 32767 
by  computing;   N  mod  32768.   This  change  appears  in  both 
TESTPRIM.BAS and FINDPRIM.BAS.
