Tanto quanto eu entendo,
ssl_verify_depth 2;
deve fazer o truque. Consulte o link para obter detalhes.
Estou tentando configurar a autoridade de certificação raiz, a autoridade de certificação subordinada e gerar os certificados de cliente assinados por qualquer uma dessas CAs que o nginx 0.7.67 no Debian Squeeze aceitará. Meu problema é que o certificado de cliente assinado pela CA raiz funciona bem enquanto a CA subordinada assinou um, resultando em "400 Solicitação incorreta. O erro de certificado SSL".
Etapa 1: configuração do host virtual nginx:
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/;
}
}
Etapa 2: organização da infra-estrutura PKI para as autoridades de certificação raiz e subordinada (com base em este artigo ):
# 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/
Quase nenhuma alteração foi feita no rootCA / openssl.cnf:
[ CA_default ]
dir = . # Where everything is kept
...
certificate = $dir/certs/rootca.crt # The CA certificate
...
private_key = $dir/private/rootca.key # The private key
e para 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
Etapa 3: geração de certificado de CA raiz autoassinado:
# 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 []:
Etapa 4: geração de certificado de CA subordinada:
# 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.

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 []:
Etapa 5: assinatura de certificado CA subordinado por certificado CA raiz:
# 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
Etapa 6: geração e assinatura de certificado de servidor pela CA raiz (para host virtual nginx):
# 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

# openssl ca -in server.csr -out certs/server.crt -config openssl.cnf
Etapa 7: geração de certificado do cliente nº 1 e assinatura pela autoridade de certificação raiz:
# 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

# openssl pkcs12 -export -out certs/client1.p12 -inkey private/client1.key -in certs/client1.crt -certfile certs/rootca.crt
Etapa 9: geração do certificado do cliente nº 2 e assinatura pela autoridade de certificação subordinada:
# cd ../subCA/
# openssl genrsa -out ./private/client2.key -des3 2048
# openssl req -new -key ./private/client2.key -out client2.csr -config openssl.cnf

# openssl pkcs12 -export -out certs/client2.p12 -inkey private/client2.key -in certs/client2.crt -certfile certs/subca.crt
Etapa 11: passando o certificado do servidor e a chave privada para o nginx (executado com privilégios de superusuário do sistema operacional):
# cd ../rootCA/
# cp -v certs/server.crt /etc/nginx/ssl/
# cp -v private/server.key /etc/nginx/ssl/
Etapa 12: Transmitindo certificados de autoridade de certificação raiz e subordinados para o nginx (executado com privilégios de superusuário do sistema operacional):
# cat certs/rootca.crt > /etc/nginx/ssl/client.pem
# cat ../subCA/certs/subca.crt >> /etc/nginx/ssl/client.pem
client.pem tem esta aparência:
# cat /etc/nginx/ssl/client.pem

Estou recebendo o erro # 20 do OpenSSL e, em seguida, # 27. De acordo com a documentação :
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.
Tanto quanto eu entendo,
ssl_verify_depth 2;
deve fazer o truque. Consulte o link para obter detalhes.
Ok, não é um bug, é um recurso;)
Eu também tive esse "problema", a solução e a explicação estão aqui: link (fonte: link )
Nesta configuração:
RootCA -> IntermediateCA1 -> Client1
RootCA -> IntermediateCA2 -> Client2
se eu quiser dar acesso apenas ao Client1 (e outros certificados assinados pelo IntermediateCA1), eu uso esta configuração:
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;
}
}
Para os documentos , tente anexar o certificado CA intermediário ao arquivo especificado por ssl_certificate ? Parece que está sendo anexado ao final do arquivo que você especificou para ssl_client_certificate .
Então, em vez disso:
# cat certs/rootca.crt > /etc/nginx/ssl/client.pem
# cat ../subCA/certs/subca.crt >> /etc/nginx/ssl/client.pem
Tente isto:
# cat certs/rootca.crt > /etc/nginx/ssl/client.pem
# cat ../subCA/certs/subca.crt >> /etc/nginx/ssl/server.crt
Como @Maxim Dounin observou, ssl_verify_depth 2; deve fazer o truque. A razão para isso é porque, por padrão, ssl_verify_depth == 1 e nginx apenas não conseguem verificar seus certificados com profundidade == 2 (Root + Intermediate)
De acordo com esta discussão nginx falha verificar certificados assinados por autoridades de certificação intermediárias.
From what I have found nginx doesn't accept a cert chain as you would expect when you have one as the client ca. It appears as if it would accept any certificate from any ca in the chain. I have RootCA > In-House CA > Client CA > Client Cert... One would expect that if the cert for Client CA were to be provided as the client ca then certs signed by client ca are valid. I have not had success with any Intermediate CA as the client ca. It works perfectly fine with a self-signed Root CA for the client certs. – Steve Buzonas Jun 2 '12 at 21:21
