The exampletrust.jks store will be used in the TrustManager. Owner: CN=exampleCA, OU=Example Org, O=Example Company, L=San Francisco, ST=California, C=US You should see a trustedCertEntry for exampleca: Alias name: exampleca # List out the details of the store password. # Create a JKS keystore that trusts the example CA, with the default password. Many java clients prefer to have the trust store in JKS format. Generate a trust store which contains only the certificate and hand that out to clients. Configuring a Trust StoreĪny clients need to see that the server’s certificate is trusted, but don’t need to see the private key. There are two parts to setting up a client – configuring a trust store, and configuring client authentication. You can check the certificate is what you expect by checking the server: keytool -printcert -sslserver If you are using client authentication (covered in Client Configuration below), you will also need to add: ssl_client_certificate /etc/nginx/certs/clientca.crt Now that you have both (the public key certificate) and (the private key), you can set up an HTTPS server.įor example, to use the keys in nginx, you would set the following in nf: ssl_certificate /etc/nginx/certs/ # Export the private key for use in nginx. # Create a PKCS#12 keystore containing the public and private keys. # Export 's public certificate for use with nginx. Unfortunately, keytool does not export private key information, so openssl must be installed to pull private keys. If does not use Java as a TLS termination point, and you are using nginx, you may need to export the certificates in PEM format. Issuer: CN=exampleCA, OU=Example Org, O=Example Company, L=San Francisco, ST=California, C=USĬonfiguring certificates in Nginx Owner: CN=, OU=Example Org, O=Example Company, L=San Francisco, ST=California, C=US # If you are using Play as a TLS termination point, this is the key store you should present as the server. # List out the contents of just to confirm it. # Import the signed certificate back into # Tell it can trust exampleca as a signer. ext KeyUsage:critical="digitalSignature,keyEncipherment" \ # Technically, keyUsage should be digitalSignature for DHE or ECDHE, keyEncipherment for RSA. Note the extension is on the request, not the # Tell exampleCA to sign the certificate. # Create a certificate signing request for dname "CN=, OU=Example Org, O=Example Company, L=San Francisco, ST=California, C=US" \ The certificate is presented by the server in the handshake. # Export the exampleCA public certificate as exampleca.crt so that it can be used in trust stores. ext BasicConstraints:critical="ca:true" \ dname "CN=exampleCA, OU=Example Org, O=Example Company, L=San Francisco, ST=California, C=US" \ # Create a self signed key pair root CA certificate. The root CA certificate has a couple of additional attributes (ca:true, ke圜ertSign) that mark it explicitly as a CA certificate, and will be kept in a trust store. The first step is to create a certificate authority that will sign the certificate. In this example, we assume the hostname is. You will need a server with a DNS hostname assigned, for hostname verification. Generating a random passwordĬreate a random password using pwgen ( brew install pwgen if you’re on a Mac): export PW=`pwgen -Bs 10 1` The examples below use keytool 1.8 for marking a certificate for CA usage or for a hostname. Use the keytool version that comes with JDK 8: This is why certificate verification is so important: accepting any certificate means that even an attacker’s certificate will be blindly accepted. Certificates are used to establish information about the bearer of that information in a way that is difficult to forge. The best way to think about public key certificates is as a passport system. Public key certificates solve this problem. Without some means to verify the identity of a remote server, an attacker could still present itself as the remote server and then forward the secure connection onto the remote server. Encryption alone is enough to set up a secure connection, but there’s no guarantee that you are talking to the server that you think you are talking to. Public key certificates are a solution to the problem of identity. Generating X.509 Certificates X.509 Certificates
