Use keytool (provided with the JDK) to manipulate the keys and certificates.


  1. Create two key pairs:
    1. One for the server (used for SSL)
    2. One as an example on the client side (used for "trust")
      It should be performed for each client.
    mkdir -p etc/keystores
    cd etc/keystores
    keytool -genkey -keyalg RSA -validity 365 -alias serverkey -keypass password -storepass password -keystore keystore.jks
    keytool -genkey -keyalg RSA -validity 365 -alias clientkey -keypass password -storepass password -keystore client.jks

    These keys are self-designed. In a production system, you should use a Certificate Authority (CA).

  2. Export the client certificate to be imported in the server keystore:
    keytool -export -rfc -keystore clientKeystore.jks -storepass password -alias clientkey -file client.cer
    keytool -import -trustcacerts -keystore keystore.jdk -storepass password -alias clientkey -file client.cer
  3. Check that the client certificate is trusted in our keystore:
    keytool -list -v -keystore keystore.jks
    Alias name: clientkey
    Creation date: Aug 28, 2018
    Entry type: trustedCertEntry
  4. Remove the client.cer certificate.
