<div dir="ltr">Hi, <div><br></div><div>I am just following up with my earlier mail as I did not get an answer. I now understand that the heartbeat mechanism is completely removed in OpenSSL 1.1.1, whereas it's still available in gnuTLS. So I do not understand why it was removed from OpenSSL</div><div> Having your own keepalive mechanism(at application level) the only way forward ?
I am still looking for some answers.
Can someone throw some light on it ?</div><div><br></div><div>Regards,</div><div>Vijay</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Jun 9, 2020 at 2:25 PM Vijayakumar Kaliaperumal <<a href="mailto:vkaliape@gmail.com">vkaliape@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hello, <div><br></div><div>From the release notes of OpenSSL 1.1.1, I could see that DTLS heartbeat has been removed</div><div>. </div><div><span style="font-family:"PT Serif",Georgia,Times,"Times New Roman",serif;font-size:18.4px;background-color:rgb(248,248,248)">Heartbeat support has been removed; the ABI is changed for now.</span> <br></div><div><br></div><div>With RFC 6520 in standards track, any specific reason(Vulnerability/other security issue reported) for the removal ?, How can we re-enable it ?
