是否可以使用 mod_gnutls 和 Apache 2 配置 ECDHE-ECDSA?

是否可以使用 mod_gnutls 和 Apache 2 配置 ECDHE-ECDSA?

我正在尝试配置我的 Debian 盒子并mod_gnutls实现(为了 SNI),以获得最佳结果TLSv1.0/1.1/1.2(不考虑 SSL2 和 SSL3)

然而在我看来,在 中使用ECDHE-ECDSA/是不可能的,而可以使用ECDHE-RSAmod_gnutlsgnutls-cli

+ECDHE-RSA:+ECDHE-ECDSA触发GnuTLSPriorities错误Syntax error parsing priorities string at ...

我当前的配置行:

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

其中输出nmap

我的软件版本是:

  • libapache2-修改-gnutls
    • 0.5.10-1.1
  • 阿帕奇2
    • 2.2.22-13+deb7u3
  • gnutls-bin
    • 3.3.8-3

答案1

嗯,原来是libapache2-mod-gnutls版本问题。

版本0.5.X与 链接libgnutls26,不包含这些密码
版本0.6.X与 链接libgnutls28,包含 ECDHE-RSA/ECDHE-ECDSA

所以解决方案有两个:

  • 升级到 libapache2-mod-gnutls 的新版本,需要Apache 2.4
  • 使用 Apache 2.2 版本中包含的 OpenSSL,并进行适当配置

libapache2-mod-gnutls 的有效配置是:

GnuTLSPriorities    NONE:+SHA512:+SHA384:+SHA256:+ECDHE-RSA:+ECDHE-ECDSA:+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

apache2(openssl)的有效配置是:

SSLCipherSuite ECDHE-ECDSA-AES256-SHA:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:RC4-RSA:HIGH:!MD5:!aNULL
SSLHonorCipherOrder     on
SSLCompression          off
SSLProtocol all -SSLv2 -SSLv3
Header add Strict-Transport-Security "max-age=15768000"
