浏览器过时的encryption警告
我已经开始使用Apache 2.4和SSL的Windows Server。 当我连接到https://www.example.com并点击绿色锁，我有消息：
您的网站连接使用过时的密码encryption
有什么build议吗？
以下是ssl.conf ：
# # This is the Apache server configuration file providing SSL support. # It contains the configuration directives to instruct the server how to # serve pages over an https connection.

This means that # the standard Auth/DBMAuth methods can be used for access control. The # user name is the `one line' version of the client's X.509 certificate. # Note that no password is obtained from the user. Every entry in the user # file needs this password: `xxj31ZMTZzkVA'. # o ExportCertData: # This exports two additional environment variables: SSL_CLIENT_CERT and # SSL_SERVER_CERT. These contain the PEM-encoded certificates of the # server (always existing) and the client (only existing when client # authentication is used). This can be used to import the certificates # into CGI scripts. # o StdEnvVars: # This exports the standard SSL/TLS related `SSL_*' environment variables. # Per default this exportation is switched off for performance reasons, # because the extraction step is an expensive operation and is usually # useless for serving static content. So one usually enables the # exportation for CGI and SSI requests only. # o StrictRequire: # This denies access when "SSLRequireSSL" or "SSLRequire" applied even # under a "Satisfy any" situation, ie when it applies access is denied # and no other module can change it. # o OptRenegotiate: # This enables optimized SSL connection renegotiation handling when SSL # directives are used in per-directory context. #SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire <FilesMatch "\.(cgi|shtml|phtml|php)$"> SSLOptions +StdEnvVars </FilesMatch> <Directory "c:/Apache24/cgi-bin"> SSLOptions +StdEnvVars </Directory> # SSL Protocol Adjustments: # The safe and default but still SSL/TLS standard compliant shutdown # approach is that mod_ssl sends the close notify alert but doesn't wait for # the close notify alert from client. When you need a different shutdown # approach you can use one of the following variables: # o ssl-unclean-shutdown: # This forces an unclean shutdown when the connection is closed, ie no # SSL close notify alert is sent or allowed to be received. This violates # the SSL/TLS standard but is needed for some brain-dead browsers. Use # this when you receive I/O errors because of the standard approach where # mod_ssl sends the close notify alert. # o ssl-accurate-shutdown: # This forces an accurate shutdown when the connection is closed, ie a # SSL close notify alert is send and mod_ssl waits for the close notify # alert of the client. This is 100% SSL/TLS standard compliant, but in # practice often causes hanging connections with brain-dead browsers. Use # this only for browsers where you know that their SSL implementation # works correctly. # Notice: Most problems of broken clients are also related to the HTTP # keep-alive facility, so you usually additionally want to disable # keep-alive for those clients, too. Use variable "nokeepalive" for this. # Similarly, one has to force some clients to use HTTP/1.0 to workaround # their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and # "force-response-1.0" for this. BrowserMatch "MSIE [2-5]" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 # Per-Server Logging: # The home of a custom SSL log file. Use this when you want a # compact non-error SSL logfile on a virtual host basis. CustomLog "c:/Apache24/logs/ssl_request.log" \ "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b" </VirtualHost>
过时的密码套件
你可能会看到：
“您与example.com的连接使用过时的encryption技术进行encryption。”
这意味着与当前网站的连接正在使用过时的密码套件（如果服务器坚持，Chrome仍然允许）。
为了使消息表明“现代密码学”，连接应该使用正向保密，AES-GCM或CHACHA20_POLY1305。 其他密码套件已知有弱点。 大多数服务器将希望协商TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256。
所有这一切归结到您的configuration中的以下几行，确定哪些密码套件支持和优先与客户端连接。

有什么build议吗？
HIGH:MEDIUM:!aNULL:!MD5的SSLCipherSuite HIGH:MEDIUM:!aNULL:!MD5也不错。 你应该把它改为HIGH:!aNULL:!MD5:!RC4因为MEDIUM很弱而RC4弱/受伤。
浏览器正在标记/警告RC4的使用。 例如，请参阅连接信息声明RC4是“高级”
如果您只想使用短暂或临时的Diffie-Hellman密钥（您应该），那么您也应该删除RSA密钥传输：
SSLCipherSuite HIGH:!aNULL:!kRSA:!MD5:!RC4
正如Anand指出的，您应该禁用SSLv2和SSLv3：
SSLProtocol all -SSLv2 -SSLv3
相关的，你可以根据openssl ciphers命令使用的string得到启用的密码套件列表。 由于您不使用DSS，SRP或PSK，甚至可以在string中包括!DSS:!DSA:!SRP:!PSK 。
