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

Procedure

  1. Create two key pairs:
    1. One pair for the server (used for SSL)
    2. One pair as an example on the client side (used for "trust")
      The key pair on the client side must be created 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 client.jks -storepass password -alias clientkey -file client.cer
    keytool -import -trustcacerts -keystore keystore.jks -storepass password -alias clientkey -file client.cer
  3. Verify that the client certificate is trusted in the server keystore:
    keytool -list -v -keystore keystore.jks
    ...
    Alias name: clientkey
    Creation date: Aug 28, 2018
    Entry type: trustedCertEntry
    ...
  4. Remove the client.cer certificate.
