An Android app for our "keyholder" to view and manage the door states.
It uses an mqtt service to get the current status and sends door commands per ssh.
We need a Android compatible keystore with the endpoint's ssl certificate in it. Download the bcprov-ext-jdk14-1.53.jar, e.g. from here and run:
echo -n | openssl s_client -connect mainframe.io:8883 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > mqtt_mainframe.io.crt
keytool -import -trustcacerts -keystore hacs_keystore.bks -storepass keystorepw -noprompt -alias mqtt_mainframe -file mqtt_mainframe.io.crt -storetype BKS -providerClass org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath bcprov-ext-jdk14-1.53.jarCopy the resulting hacs_keystore.bks to the src/main/assets/keystore/ folder.
Must start with mf-door. and end with .key and must have a password.
