<p class="MsoNormal"><br>
In order to make this rule a little clearer, we suggest changing it to:<br>
<br>
"Effective XXXX, 2016, CAs SHALL use a Certificate serialNumber greater than zero (0) that exhibits at least 64 bits of entropy for all issued certificates, including CA certificates".<br>
<br>
Since this discussion begun in February, I suppose the effective date will be adjusted accordingly to a date after the ballot and not "April 1, 2016".<br>
