HTTPS Configuration

Getting the Certificate

To enable HTTPS web access, you will need a server certificate in a java keystore. To create a self-signed certificate, for testing and non-production use, you can use the tool keytool from your Java distribution. (A self-signed certificate will cause a warning to be displayed by a browser when viewing the page. The various browsers each have ways to import the certificate as a trusted one, for test purposes.)

The following command creates a self-signed certificate and adds it to a keystore, keystore.jks:

% keytool -genkey -keyalg RSA -alias brooklyn \
          -keystore <path-to-keystore-directory>/keystore.jks -storepass "mypassword" \
          -validity 365 -keysize 2048 -keypass "password"

The passwords above should be changed to your own values. Omit those arguments above for the tool to prompt you for the values.

You will then be prompted to enter your name and organization details. This will use (or create, if it does not exist) a keystore with the password mypassword - you should use your own secure password, which will be the same password used in your brooklyn.cfg (below). You will also need to replace <path-to-keystore-directory> with the full path of the folder where you wish to store your keystore. The keystore will contain the newly generated key, with alias brooklyn and password password.

For production servers, a valid signed certificate from a trusted certifying authority should be used instead. Typically keys from a certifying authority are not provided in Java keystore format. To create a Java keystore from existing certificates (CA certificate, and public and private keys), you must first create a PKCS12 keystore from them, for example with openssl; this can then be converted into a Java keystore with keytool. For example, with a CA certificate ca.pem, and public and private keys cert.pem and key.pem, create the PKCS12 store server.p12, and then convert it into a keystore keystore.jks as follows:

% openssl pkcs12 -export -in cert.pem -inkey key.pem \
               -out server.p12 -name "brooklyn" \
               -CAfile ca.pem -caname root -chain -passout pass:"password"

% keytool -importkeystore \
        -deststorepass "password" -destkeypass "password" -destkeystore keystore.jks \
        -srckeystore server.p12 -srcstoretype PKCS12 -srcstorepass "password" \
        -alias "brooklyn"
