Previously we added ssl<\/a> to an Nginx server. On this example we shall enhance our security by adding mTLS to Nginx.<\/p>\n\n\n\n

Apart from encrypting the traffic between client and server, SSL is also a way for the client to make sure that the server connecting to, is a trusted source.<\/p>\n\n\n\n

On the other hand mTLS is a way for the server to ensure that the client is a trusted one. The client does accept the SSL connection to the server however it has to present to the server a certificate signed from an authority that the Server accepts. This way the Server, by validating the certificate the client presents can allow the connection.<\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

More or less we shall build upon the previous example. The ssl certificates shall be the same, however we shall add the configuration for mtls.<\/p>\n\n\n\n

The server ssl creation.<\/p>\n\n\n\n

mkdir certs\n\ncd certs\n\nopenssl genrsa -des3 -out ca.key 4096\n#Remove passphrase for example purposes\nopenssl rsa -in ca.key -out ca.key\nopenssl req -new -x509 -days 3650 -key ca.key -subj \"\/CN=*.your.hostname\" -out ca.crt\n\nprintf test > passphrase.txt\nopenssl genrsa -des3 -passout file:passphrase.txt -out server.key 2048\nopenssl req -new -passin file:passphrase.txt -key server.key -subj \"\/CN=*.your.hostname\" -out server.csr\n\nopenssl x509 -req -days 365 -in server.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out server.crt<\/pre>\n\n\n\n
The above is sufficient to secure out Nginx with SSL. So let\u2019s create the mTLS certificates for the clients.
In order to create a certificate for mTLS we need a certificate authority. For convenience the certificate authority will be the same as the one we generated on the previous example.<\/p>\n\n\n\n
printf test > client_passphrase.txt\nopenssl genrsa -des3 -passout file:client_passphrase.txt -out client.key 2048\nopenssl rsa -passin file:client_passphrase.txt -in client.key -out client.key\nopenssl req -new -key client.key -subj \"\/CN=*.client.hostname\" -out client.csr\n\n##Sign the certificate with the certificate authority\nopenssl x509 -req -days 365 -in client.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out client.crt<\/pre>\n\n\n\n
Take note that the client common name needs to be different from the server\u2019s certs common name, or else your request will be reject.<\/p>\n\n\n\n
So we have our client certificate generated.
The next step is to configure Nginx to force mTLS connections from a specific authority<\/p>\n\n\n\n
server {\nerror_log \/var\/log\/nginx\/error.log debug;\n    listen 443 ssl;\n    server_name  test.your.hostname;\n    ssl_password_file \/etc\/nginx\/certs\/password;\n    ssl_certificate \/etc\/nginx\/certs\/tls.crt;\n    ssl_certificate_key \/etc\/nginx\/certs\/tls.key;\n\n    ssl_client_certificate \/etc\/nginx\/mtls\/ca.crt;\n    ssl_verify_client on;\n    ssl_verify_depth  3;\n\n    ssl_protocols             TLSv1 TLSv1.1 TLSv1.2;\n\n    location \/ {\n    }\n\n}<\/pre>\n\n\n\n
By using the ssl_client_certificate we point to the certificate authority that the client certificates should be signed from.
By using the ssl_verify_client as on, we enforce mTLS connections.<\/p>\n\n\n\n
Since we have all certificates generated let\u2019s spin up the Nginx server using docker.<\/p>\n\n\n\n
docker run --rm --name mtls-nginx -p 443:443 -v $(pwd)\/certs\/ca.crt:\/etc\/nginx\/mtls\/ca.crt -v $(pwd)\/certs\/server.key:\/etc\/nginx\/certs\/tls.key -v $(pwd)\/certs\/server.crt:\/etc\/nginx\/certs\/tls.crt -v $(pwd)\/nginx.mtls.conf:\/etc\/nginx\/conf.d\/nginx.conf -v $(pwd)\/certs\/passphrase.txt:\/etc\/nginx\/certs\/password nginx<\/pre>\n\n\n\n
Our server is up and running. Let\u2019s try to do a request using curl without using any client certificates.<\/p>\n\n\n\n
curl https:\/\/localhost\/ --insecure<\/pre>\n\n\n\n
The result shall be<\/p>\n\n\n\n
<html>\n<head><title>400 No required SSL certificate was sent<\/title><\/head>\n<body>\n<center><h1>400 Bad Request<\/h1><\/center>\n<center>No required SSL certificate was sent<\/center>\n<hr><center>nginx\/1.21.3<\/center>\n<\/body>\n<\/html><\/pre>\n\n\n\n
As expected our request is rejected.
Let\u2019s use the client certificates we generated from the expected certificate authority.<\/p>\n\n\n\n
curl --key certs\/client.key --cert certs\/client.crt https:\/\/127.0.0.1 --insecure<\/pre>\n\n\n\n
<html>\n<head><title>404 Not Found<\/title><\/head>\n<body>\n<center><h1>404 Not Found<\/h1><\/center>\n<hr><center>nginx\/1.21.3<\/center>\n<\/body>\n<\/html><\/pre>\n\n\n\n
The connection was established and the client could connect to the Nginx instance.<\/p>\n\n\n\n
Let\u2019s put them all together<\/p>\n\n\n\n
mkdir certs\n\ncd certs\n\nopenssl genrsa -des3 -out ca.key 4096\n#Remove passphrase for example purposes\nopenssl rsa -in ca.key -out ca.key\nopenssl req -new -x509 -days 3650 -key ca.key -subj \"\/CN=*.your.hostname\" -out ca.crt\n\nprintf test > passphrase.txt\nopenssl genrsa -des3 -passout file:passphrase.txt -out server.key 2048\nopenssl req -new -passin file:passphrase.txt -key server.key -subj \"\/CN=*.your.hostname\" -out server.csr\n\nopenssl x509 -req -days 365 -in server.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out server.crt\n\nprintf test > client_passphrase.txt\nopenssl genrsa -des3 -passout file:client_passphrase.txt -out client.key 2048\nopenssl rsa -passin file:client_passphrase.txt -in client.key -out client.key\nopenssl req -new -key client.key -subj \"\/CN=*.client.hostname\" -out client.csr\n\n##Sign the certificate with the certificate authority\nopenssl x509 -req -days 365 -in client.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out client.crt\n\ncd ..\/\n\ndocker run --rm --name mtls-nginx -p 443:443 -v $(pwd)\/certs\/ca.crt:\/etc\/nginx\/mtls\/ca.crt -v $(pwd)\/certs\/server.key:\/etc\/nginx\/certs\/tls.key -v $(pwd)\/certs\/server.crt:\/etc\/nginx\/certs\/tls.crt -v $(pwd)\/nginx.mtls.conf:\/etc\/nginx\/conf.d\/nginx.conf -v $(pwd)\/certs\/passphrase.txt:\/etc\/nginx\/certs\/password nginx<\/pre>\n\n\n\n
