node.js – 服务器端的客户端证书验证,DEPTH_ZERO_SELF_SIGNED_CERT错误

我正在使用节点0.10.26并尝试建立与客户端验证的https连接.

服务器代码：

var https = require('https');
var fs = require('fs');

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

var options = {
    key: fs.readFileSync('ssl/server1.key'),
    cert: fs.readFileSync('ssl/server1.pem'),
    requestCert: true,
    rejectUnauthorized: false,
};

var server = https.createServer(options, function (req, res) {
    if (req.client.authorized) {
        res.writeHead(200, {"Content-Type":"application/json"});
        res.end('{"status":"approved"}');
        console.log("Approved Client ", req.client.socket.remoteAddress);
    } else {
        console.log("res.connection.authroizationError:  " + res.connection.authorizationError);
        res.writeHead(403, {"Content-Type":"application/json"});
        res.end('{"status":"denied"}');
        console.log("Denied Client " , req.client.socket.remoteAddress);
    }
});

server.on('error', function(err) {
    console.log("server.error: "  + err);
});

server.on("listening", function () {
    console.log("Server listeining");
});

server.listen(5678);

客户代码：

var https = require('https');
var fs = require('fs');

var options = {
    host: 'localhost',
    port: 5678,
    method: 'GET',
    path: '/',
    headers: {},
    agent: false,
    key: fs.readFileSync('ssl/client2.key'),
    cert: fs.readFileSync('ssl/client2.pem'),
    ca: fs.readFileSync('ssl/ca.pem')
};

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

var req = https.request(options, function(res) {
    console.log(res.req.connection.authorizationError);
});

req.on("error", function (err) {
    console.log('error: ' + err);
});

req.end();

我已经使用以下命令创建了证书,每次提供“uname -n”作为“公用名称”的结果：

openssl genrsa -out ca.key 4096
openssl req -x509 -new -nodes -key ca.key -days 999 -out ca.pem

openssl genrsa -out server1.key  1024
openssl req -new -key server1.key -out server1.csr
openssl x509 -req -days 999 -in server1.csr -CA ca.pem  -CAkey ca.key -set_serial 01 -out server1.pem

openssl genrsa  -out client1.key 1024
openssl req -new -key client1.key  -out client1.csr
openssl  x509  -req -days 999 -in client1.csr  -CA ca.pem  -CAkey ca.key  -set_serial 01     -out client1.pem

openssl genrsa  -out server2.key 1024
openssl req -new -key server2.key  -out server2.csr
openssl  x509  -req -days 999 -in server2.csr -CA server1.pem -CAkey server1.key -     set_serial 02 -out server2.pem

openssl  genrsa -out client2.key 1024
openssl req -new -key client2.key -out client2.csr
openssl x509 -req -days 999 -in client2.csr -CA client1.pem -CAkey client1.key  -set_serial 02 -out client2.pem

我已经运行客户端和服务器,其中包含客户端和服务器证书(即[(server1,client1),(server1,client2),(server2,client1),(server2,client2)]以及其中的每个组合服务器测试了默认值“agent”字段,“agent”设置为“false”.

每次运行client.js时,res.req.connection.authorizationError设置为DEPTH_ZERO_SELF_SIGNED_CERT.

如何在客户端证书身份验证的节点中建立安全连接？

 

我相信你有两个问题,一个是你的代码,一个是你的证书.

代码问题在您的服务器中.您没有指定CA来检查具有您客户端代码中的选项属性的客户端证书：

ca: fs.readFileSync('ssl/ca.pem'),

第二个问题是真正导致DEPTH_ZERO_SELF_SIGNED_CERT错误的问题.您正在将所有证书(CA,服务器和客户端)都提供给相同的可分辨名称.当服务器从客户端证书中提取颁发者信息时,会发现发行者DN与客户端证书DN相同,并得出客户端证书是自签名的.

尝试重新生成证书,给每个证书一个唯一的通用名称(使DN也是唯一的).例如,将您的CA证书“Foo CA”命名,您的服务器证书是您的主机名称(在这种情况下为“localhost”),您的客户端将其名称(例如“Foo Client 1”)命名.
