我正在尝试使用mod_gnutls实现（为了SNI）configuration我的Debian盒子，以在TLSv1.0/1.1/1.2 （忽略TLSv1.0/1.1/1.2和SSL3）中实现最佳的结果。
但是在我看来，在mod_gnutls使用ECDHE-ECDSA / ECDHE-RSA是不可能的，而在gnutls-cli
+ECDHE-RSA:+ECDHE-ECDSA在GnuTLSPriorities触发错误Syntax error parsing priorities string at ...
我目前的configuration线：
GnuTLSPriorities NONE:+SHA512:+SHA384:+SHA256:+DHE-RSA:+DHE-PSK: +DHE-DSS:+AES-256-CBC:+AES-128-CBC:+3DES-CBC:+VERS-TLS1.2: +VERS-TLS1.1:+VERS-TLS1.0:+COMP-NULL:+SHA1:+SIGN-ALL
哪里输出nmap

我的软件版本是：
那么，事实certificate，问题是在libapache2-mod-gnutls版本。
版本0.5.X与libgnutls26链接，不包含这些密码
版本0.6.X与包含ECDHE-RSA / ECDHE-ECDSA的0.6.X链接
所以解决scheme是两个：
Apache 2.4 libapache2-mod-gnutls的有效configuration是：
