$ keytool \
    -genkeypair \
    -keystore keystore.p12 \

    -dname "CN=$HOSTNAME" \
    -keyalg RSA \
    -keypass Secret.123

$ keytool \
    -genkeypair \
    -keystore keystore.p12 \
    -storetype pkcs12 \
    -storepass Secret.123 \
    -alias sslserver \
    -dname "CN=$HOSTNAME" \
    -keyalg EC \
    -keypass Secret.123
