<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">Thanks for answering my question.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">Since the SHA-1 hash function is considered vulnerable, will there be an effort to modify the hard coded entry to one that isn’t as vulnerable?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">Starting with version 56, Google Chrome will mark all SHA-1-signed HTTPS certificates as unsafe. Other major browser vendors plan to do the same.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">Since we are using this for WebRTC it seems that a modification to the code is warranted.<o:p></o:p></span></p>
