+	  <p>In the OpenSSL address implementation the hard coded 1024
+	    bit DH p parameter was not prime. The effective cryptographic strength
+	    of a key exchange using these parameters was weaker than the one one
+	    could get by using a prime p. Moreover, since there is no indication of
+	    how these parameters were chosen, the existence of a trapdoor that makes
+	    possible for an eavesdropper to recover the shared secret from a key
+	    exchange that uses them cannot be ruled out.</p>
