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

我可以通过证书获得服务器端身份验证，但是当我使用证书添加客户端身份验证时，我收到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？

【问题讨论】：

【参考方案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)

您可能在绑定中使用错误的等效项配置服务器。

你用openssl s_server测试过吗？
