我正在尝试设置根证书颁发机构、下属证书颁发机构并生成由 Debian Squeeze 上的 nginx 0.7.67 接受的此 CA 签名的客户端证书。我的问题是根 CA 签名的客户端证书工作正常，而下属 CA 签名的证书则导致“400 错误请求。SSL 证书错误”。
步骤1：nginx虚拟主机配置：
server {
server_name test.local;
access_log /var/log/nginx/test.access.log;
listen 443 default ssl;
keepalive_timeout 70;
ssl_protocols SSLv3 TLSv1;
ssl_ciphers AES128-SHA:AES256-SHA:RC4-SHA:DES-CBC3-SHA:RC4-MD5;
ssl_certificate /etc/nginx/ssl/server.crt;
ssl_certificate_key /etc/nginx/ssl/server.key;
ssl_client_certificate /etc/nginx/ssl/client.pem;
ssl_verify_client on;
ssl_session_cache shared:SSL:10m;
ssl_session_timeout 5m;
location / {
proxy_pass http://testsite.local/;
}
}
步骤 2：根 CA 和从属 CA 的 PKI 基础设施组织（基于这文章）：
# mkdir ~/pki && cd ~/pki
# mkdir rootCA subCA
# cp -v /etc/ssl/openssl.cnf rootCA/
# cd rootCA/
# mkdir certs private crl newcerts; touch serial; echo 01 > serial; touch index.txt; touch crlnumber; echo 01 > crlnumber
# cp -Rvp * ../subCA/
rootCA/openssl.cnf 几乎没有任何改变：
[ CA_default ]
dir = . # Where everything is kept
...
certificate = $dir/certs/rootca.crt # The CA certificate
...
private_key = $dir/private/rootca.key # The private key
以及 subCA/openssl.cnf：
[ CA_default ]
dir = . # Where everything is kept
...
certificate = $dir/certs/subca.crt # The CA certificate
...
private_key = $dir/private/subca.key # The private key
步骤3：自签名根CA证书生成：
# openssl genrsa -out ./private/rootca.key -des3 2048
# openssl req -x509 -new -key ./private/rootca.key -out certs/rootca.crt -config openssl.cnf
Enter pass phrase for ./private/rootca.key:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, YOUR name) []:rootca
Email Address []:
步骤4：从属CA证书生成：
# cd ../subCA
# openssl genrsa -out ./private/subca.key -des3 2048
# openssl req -new -key ./private/subca.key -out subca.csr -config openssl.cnf
Enter pass phrase for ./private/subca.key:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:

Organizational Unit Name (eg, section) []:
Common Name (eg, YOUR name) []:subca
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
步骤5：根CA证书签署从属CA证书：
# cd ../rootCA/
# openssl ca -in ../subCA/subca.csr -extensions v3_ca -config openssl.cnf
Using configuration from openssl.cnf
Enter pass phrase for ./private/rootca.key:
Check that the request matches the signature
Signature ok

...
# cd ../subCA/
# cp -v ../rootCA/newcerts/01.pem certs/subca.crt
步骤 6：由根 CA 生成并签名服务器证书（针对 nginx 虚拟主机）：
# cd ../rootCA
# openssl genrsa -out ./private/server.key -des3 2048
# openssl req -new -key ./private/server.key -out server.csr -config openssl.cnf
Enter pass phrase for ./private/server.key:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, YOUR name) []:test.local
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
# openssl ca -in server.csr -out certs/server.crt -config openssl.cnf
步骤 7：客户端＃1证书生成并由根CA签名：
# openssl genrsa -out ./private/client1.key -des3 2048
# openssl req -new -key ./private/client1.key -out client1.csr -config openssl.cnf
Enter pass phrase for ./private/client1.key:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:

Common Name (eg, YOUR name) []:Client #1
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
# openssl ca -in client1.csr -out certs/client1.crt -config openssl.cnf
步骤 8：客户端 #1 证书转换为 PKCS12 格式：
# openssl pkcs12 -export -out certs/client1.p12 -inkey private/client1.key -in certs/client1.crt -certfile certs/rootca.crt
步骤 9：客户端＃2 证书生成并由下属 CA 签名：
# cd ../subCA/
# openssl genrsa -out ./private/client2.key -des3 2048
# openssl req -new -key ./private/client2.key -out client2.csr -config openssl.cnf
Enter pass phrase for ./private/client2.key:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.

Common Name (eg, YOUR name) []:Client #2
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
# openssl ca -in client2.csr -out certs/client2.crt -config openssl.cnf
步骤 10：客户端＃2 证书转换为 PKCS12 格式：
# openssl pkcs12 -export -out certs/client2.p12 -inkey private/client2.key -in certs/client2.crt -certfile certs/subca.crt
步骤 11：将服务器证书和私钥传递给 nginx（以操作系统超级用户权限执行）：
# cd ../rootCA/
# cp -v certs/server.crt /etc/nginx/ssl/
# cp -v private/server.key /etc/nginx/ssl/
步骤 12：将根 CA 和从属 CA 证书传递给 nginx（以 OS 超级用户权限执行）：
# cat certs/rootca.crt > /etc/nginx/ssl/client.pem
# cat ../subCA/certs/subca.crt >> /etc/nginx/ssl/client.pem
client.pem 文件如下所示：
# cat /etc/nginx/ssl/client.pem

所以我得到了 OpenSSL 错误 #20，然后是 #27。根据验证文档：
20 X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY: unable to get local issuer certificate
the issuer certificate could not be found: this occurs if the issuer certificate of an untrusted certificate cannot be found.
27 X509_V_ERR_CERT_UNTRUSTED: certificate not trusted
the root CA is not marked as trusted for the specified purpose.
答案1
答案2
好的，这不是一个错误，而是一个功能；）
我也遇到了这个“问题”，解决方案和解释在这里： https://stackoverflow.com/questions/8431528/nginx-ssl-certificate-authentication-signed-by-intermediate-ca-chain/14895039#14895039（来源：http://trac.nginx.org/nginx/ticket/301）
在此配置中：
RootCA -> IntermediateCA1 -> Client1
RootCA -> IntermediateCA2 -> Client2
如果我只想授予 Client1（以及由 IntermediateCA1 签名的其他证书）访问权限，我会使用以下配置：
server {
listen 443 ssl;
ssl_certificate ...
ssl_certificate_key ...
ssl_client_certificate /path/to/ca.crt;
ssl_verify_client on;
ssl_verify_depth 2;
if ($ssl_client_i_dn != "/C=PL/CN=IntermediateCA1/[email protected]") {
return 403;
}
}
答案3
根据文档，请尝试将中间 CA 证书附加到 指定的文件ssl_certificate？它似乎被附加到了您指定的文件末尾ssl_client_certificate。
所以不要这样：
# cat certs/rootca.crt > /etc/nginx/ssl/client.pem
# cat ../subCA/certs/subca.crt >> /etc/nginx/ssl/client.pem
尝试这个：
# cat certs/rootca.crt > /etc/nginx/ssl/client.pem
# cat ../subCA/certs/subca.crt >> /etc/nginx/ssl/server.crt
答案4
根据这次讨论nginx 无法检查中间认证机构签署的证书。
据我所知，nginx 并不像您预期的那样接受证书链，当您将证书链作为客户端 CA 时。它似乎会接受链中任何 CA 的任何证书。我有 RootCA > 内部 CA > 客户端 CA > 客户端证书... 人们会认为，如果客户端 CA 的证书作为客户端 CA 提供，那么由客户端 CA 签名的证书是有效的。我还没有成功使用任何中间 CA 作为客户端 CA。对于客户端证书，使用自签名根 CA 可以完美运行。– Steve Buzonas 2012 年 6 月 2 日 21:21
