階層的なOpenSSLベースの認証局からのNginxおよびクライアント証明書

ルート証明機関、下位証明機関をセットアップし、Debian Squeezeのnginx 0.7.67が受け入れるこのCAのいずれかによって署名されたクライアント証明書を生成しようとしています。私の問題は、ルートCA署名付きクライアント証明書が正常に機能するのに対し、下位CAが1つ署名すると「400 Bad Request。SSL certificate error」が発生することです。

ステップ1：nginx仮想ホスト構成：

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/;
    }
}

手順2：ルートCAと下位CAの両方のPKIインフラストラクチャ組織（ this 記事に基づく）：

# 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はほとんど変更されていません。

[ CA_default ]

dir             = .                     # Where everything is kept
...
certificate     = $dir/certs/rootca.crt # The CA certificate
...
private_key     = $dir/private/rootca.key # The private key

そしてsubCA/openssl.cnfに：

[ CA_default ]

dir             = .                     # Where everything is kept
...
certificate     = $dir/certs/subca.crt  # The CA certificate
...
private_key     = $dir/private/subca.key # The private key

ステップ3：自己署名ルートCA証明書の生成：

# 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 []:

ステップ4：下位​​CA証明書の生成：

# 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]:
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) []:subca
Email Address []:

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

ステップ5：ルートCA証明書による下位CA証明書の署名：

# 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

1 out of 1 certificate requests certified, commit? [y/n]y
...
# cd ../subCA/
# cp -v ../rootCA/newcerts/01.pem certs/subca.crt

手順6：ルートCAによるサーバー証明書の生成と署名（nginx仮想ホストの場合）：

# 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.

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

ステップ7：クライアント＃1の証明書の生成とルートCAによる署名：

# 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.

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

ステップ8：PKCS12形式に変換するクライアント＃1証明書：

# openssl pkcs12 -export -out certs/client1.p12 -inkey private/client1.key -in certs/client1.crt -certfile certs/rootca.crt

手順9：クライアント＃2の証明書の生成と下位CAによる署名：

# 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

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

ステップ10：PKCS12形式に変換するクライアント＃2証明書：

# openssl pkcs12 -export -out certs/client2.p12 -inkey private/client2.key -in certs/client2.crt -certfile certs/subca.crt

ステップ11：サーバー証明書と秘密鍵をnginxに渡す（OSスーパーユーザー権限で実行）：

# cd ../rootCA/
# cp -v certs/server.crt /etc/nginx/ssl/
# cp -v private/server.key /etc/nginx/ssl/

手順12：ルートおよび下位CA証明書をnginxに渡す（OSスーパーユーザー権限で実行）：

# cat certs/rootca.crt > /etc/nginx/ssl/client.pem
# cat ../subCA/certs/subca.crt >> /etc/nginx/ssl/client.pem

client.pemファイルは次のようになります。

# cat /etc/nginx/ssl/client.pem

すべてが正常に機能しているようです：

# service nginx reload
# Reloading nginx configuration: Enter PEM pass phrase:
# nginx.
#

ステップ13：* .p12証明書をブラウザー（私の場合はFirefox）にインストールすると、上記の問題が発生します。クライアント＃1 = 200 OK、クライアント＃2 = 400不正なリクエスト/ SSL証明書エラー。何かアイデアはありますか？

したがって、OpenSSLエラー＃20、次に＃27が発生します。検証によると ドキュメント ：

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.

私が理解する限りでは、

ssl_verify_depth 2;

トリックを行う必要があります。詳細は http://nginx.org/r/ssl_verify_depth を参照してください。

OK、それはバグではありません、それは機能です;）

私にもこの「問題」がありました、解決策と説明はここにあります： https://stackoverflow.com/questions/8431528/nginx-ssl-certificate-authentication-signed-by-intermediate-ca-chain/14895039# 14895039 （ソース： http://trac.nginx.org/nginx/ticket/301 ）

この構成では：

RootCA -> IntermediateCA1 -> Client1 
RootCA -> IntermediateCA2 -> Client2

client1（およびIntermediateCA1によって署名された他の証明書）にのみアクセスを許可する場合は、次の構成を使用します。

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;
  }
}

docs ごとに、ssl_certificate？で指定されたファイルに中間CA証明書を追加してみてください。代わりに、ssl_client_certificateに指定したファイルの末尾に追加されているようです。

これの代わりに：

# cat certs/rootca.crt > /etc/nginx/ssl/client.pem
# cat ../subCA/certs/subca.crt >> /etc/nginx/ssl/client.pem

これを試して：

# cat certs/rootca.crt > /etc/nginx/ssl/client.pem
# cat ../subCA/certs/subca.crt >> /etc/nginx/ssl/server.crt

@Maxim Douninが述べたように、ssl_verify_depth 2;トリックを行う必要があります。これは、デフォルトではssl_verify_depth == 1であり、nginxはdepth == 2（ルート+中間）で証明書を検証できないためです。
