<p>Added infor on PEM encoding</p> <p><b>New page</b></p><div>It looks like OpenSSL uses PEM encodings by default. For example:<br /> <br /> &lt;pre&gt;$ grep -R &quot;BEGIN DH PARAMETERS&quot; *<br /> apps/dh1024.pem:-----BEGIN DH PARAMETERS-----<br /> apps/dh512.pem:-----BEGIN DH PARAMETERS-----<br /> apps/dh2048.pem:-----BEGIN DH PARAMETERS-----<br /> apps/dh4096.pem:-----BEGIN DH PARAMETERS-----<br /> crypto/dh/dh1024.pem:-----BEGIN DH PARAMETERS-----<br /> crypto/dh/dh512.pem:-----BEGIN DH PARAMETERS-----<br /> crypto/dh/dh2048.pem:-----BEGIN DH PARAMETERS-----<br /> crypto/dh/dh2048.pem:-----BEGIN DH PARAMETERS-----<br /> crypto/dh/dh192.pem:-----BEGIN DH PARAMETERS-----<br /> crypto/dh/dh4096.pem:-----BEGIN DH PARAMETERS-----<br /> demos/bio/server.pem:-----BEGIN DH PARAMETERS-----<br /> doc/apps/dhparam.pod: -----BEGIN DH PARAMETERS-----&lt;/pre&gt;<br /> <br /> And I could not find any pre-encoded binary representations like in the example on this page.<br /> <br /> Should we add a sampling of IETF and NIST (2048, 3072, 4096) that are suitable for copy/paste into a program?</div>
