Question

我正在尝试运行以下命令:

[root@localhost certs]# openssl s_client -connect localhost:7043 -cert /opt/openssl-1.0.0a/ssl/certwork_client/client.crt -key /opt/openssl-1.0.0a/ssl/certwork_client/client.key -CAfile /opt/openssl-1.0.0a/ssl/certwork/ca.crt -showcerts -state -verify 2

在服务器中，我有以下代码:

certificateFile = /opt/openssl-1.0.0a/ssl/certwork/server.crt
privatKeyFile = /opt/openssl-1.0.0a/ssl/certwork/server.key
ctx = Ctx::client_server(certificateFile, privateKeyFile);
ctx->context()->verify_mode = SSL_VERIFY_PEER | SSL_VERIFY_FAIL_IF_NO_PEER_CERT | SSL_VERIFY_CLIENT_ONCE;
ctx->context()->client_CA = SSL_load_client_CA_file("/opt/openssl-1.0.0a/ssl/certwork_client/ca.crt");

context() 调用 OpenSSL 的 ssl.h 中的方法。

我使用以下命令创建了服务器 CA(证书颁发机构)和服务器证书:

cd /opt/openssl-1.0.0a/ssl
mkdir certwork
chmod 600 certwork
cd certwork
openssl genrsa -des3 -out ca.key 4096
openssl req -new -x509 -days 365 -key ca.key -out ca.crt
openssl genrsa -des3 -out server.key 4096
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 365 -in server.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out server.crt

我使用以下命令创建了客户端 CA 和客户端证书:

cd /opt/openssl-1.0.0a/ssl
mkdir certwork_client
chmod 600 certwork_client
cd certwork_client
openssl genrsa -des3 -out ca.key 4096
openssl req -new -x509 -days 365 -key ca.key -out ca.crt
openssl genrsa -des3 -out client.key 4096
openssl req -new -key client.key -out client.csr
openssl x509 -req -days 365 -in client.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out client.crt

我可以通过证书让服务器端身份验证工作，但是当我使用证书添加客户端身份验证时，我得到 tlsv1 alert unknown ca:s3_pkt.c:1193:SSL alert number 48错误。

我将客户端设置为使用服务器的 CA (/opt/openssl-1.0.0a/ssl/certwork/ca.crt)，并将服务器设置为使用客户端的 CA 文件 (/opt/openssl-1.0.0a/ssl/certwork_client/ca.crt).

我错过了什么？

Answer 1

在我看来，服务器拒绝了客户端证书。

TLS 服务器有 3 种不同的 CA 设置:

• 提供给客户端的服务器链(SSL_CTX_add_extra_chain_cert)
• 您宣布支持客户端的 CA ( SSL_CTX_set_client_CA_list )
• 您实际用于验证的 CA ( SSL_CTX_load_verify_locations )

您可能在配置服务器时使用了错误的绑定(bind)。

您是否使用 openssl s_server 进行了测试？
