我正在实施RFC 5246(TLS 1.2),并且我坚持使用证书消息。我正在使用Openssl s_client和Browsers的组合来调试服务器。服务器问候消息是接收和解释很好,并在openssl中使用-msg选项我可以看到消息已被正确解释为Client_hello,没有任何错误。
当发送证书消息时,浏览器没有响应,并且带有-msg的openssl s_client也没有响应。带有-debug的Openssl s_client读取消息但在server_hello_done消息之后没有响应。没有记录错误。
我怀疑问题在于我的证书消息的结构,因为我收到的记录层长度后发送的任何内容都没有任何错误,即使它只是随机文本或二进制数据。
将记录层的结构修改为不正确/不合适的值会引发错误并显示相应的错误消息,例如将版本设置为9.3会引发错误
5256:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
正如所料。
这是我目前使用的结构:
/ 记录图层 /
/ 握手消息数据 /
我目前正在使用自签名证书,浏览器和openssl s_client都没有在Client_hello中包含signature_algorithms扩展名,所以我按照原样,.PEM格式和纯文本发送证书.Below到目前为止是openssl的十六进制握手:

PEM当然不是发送线路的正确格式。您应该以二进制形式发送它(使用此PEM内容的base-64解码版本)。
您还需要将其包装在其他图层中,因为certificate_list
Certificate
中需要struct
。
如果您想了解更多关于这一切的信息,可能值得查看使用Wireshark的工作实现产生的现有流量。它的SSL wiki page甚至还有一个你可以使用的现有捕获文件。
(您还提到要实现TLS 1.2,但是您要发送03 01
,这是针对TLS 1.0的,尽管在实施的这个阶段这应该不重要。)< / p>
