<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Based on the replies I am seeing, I realize that my question was not clear. Let me try again.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Make a timeline for the past 15 years. Which one cipher, *<b>for each year</b>* should SSL/TLS have used? Won’t it change at least once? Move it forward
to project the cipher in use for the next 3-5 years because that’s what TLS WG is working on right now.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Once you have the list of ciphers, loosely describe the protocol changes needed to deploy. If “pick a cipher” isn’t part of the initial handshake, does it
become “pick a version”? Or does the clinet connect ‘n’ times, with the associated TCP overhead?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If FREAK shows 512K RSA can be factored in under half a day, then perhaps 1K RSA, which some have picked for the base year, can probably be factored in a week
or two. So clearly, there has to be at least one change in your timelines.<o:p></o:p></span></p>
