Dear Maintainer,<br>

At the moment it is only possible to have encrypted
communications using certificates signed with SHA1 but this is
considered insecure.<br>

Hi Ondřej,<br>
<br>
Thank you for looking into this.<br>
I have tried using a certificate from a real CA that signs
certificates with SHA256, but clients could not connect using ssl
(the error message was: ERROR 2026 (HY000): SSL connection error:
protocol version mismatch).<br>
Without changing the config, but just using a self signed
certificate signed using SHA1 everything works fine.<br>
<br>
It looks like it might be the version of YaSSL used in the package
does not support SHA256.<br>
<br>
Kind regards,<br>
<br>
Kristian<br>
