 This program should use the Diffie-Helman algorithm for public key
 encryption, not the RSA algorithm, because the Diffie-Helman patent in
 the US will expire in 1997.  It should use triple-DES, not IDEA, for
-block encryption because IDEA is patented in many countries and the
+block encryption, because IDEA is patented in many countries and the
 patents will not expire soon.  In other respects, it should be like PGP.
 
 This program needs to be written by someone who is not a US citizen,
 outside the US, to avoid problems with US export control law.
