apache SSL证书安全优化

Apache主要依赖于OpenSSL支持，请更新至最新的openssl版本，apache2.4+支持TLS1.2协议

<VirtualHost *:443>
    SSLEngine on
    SSLCertificateFile      /server.crt
    SSLCertificateKeyFile   /server.key
    # HSTS 必须开启 mod_headers模块
    Header always set Strict-Transport-Security "max-age=15768000"

</VirtualHost>

#禁用 SSLV3 SSLV2不安全的协议
SSLProtocol             all -SSLv3 -SSLv2

#优化加密算法 
SSLCipherSuite EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH
#允许加密算法排序
SSLHonorCipherOrder     on
SSLCompression          off
SSLSessionTickets       off

# OCSP Stapling, httpd 2.3.3之后的版本支持
SSLUseStapling          on
SSLStaplingResponderTimeout 5
SSLStaplingReturnResponderErrors off
SSLStaplingCache "shmcb:logs/stapling-cache(150000)" 

#apache 2.4.8 /openssl 1.0.2 之后才支持 DHParams
SSLOpenSSLConfCmd DHParameters "dhparams.pem"
