I have finally started to 'build' the Native Mobile App for Android. Following the online help, step one is to build the Keystore File. I'm running MacOS Catalina and download+installed JDK 14. entered the following line in terminal modifying the items specific to my App.

keytool -genkeypair -dname "cn=John Doe, ou=Development, o=StackIdeas, c=US" -alias easysocial -keypass password -keystore /path/to/file.jks -storepass password -validity 20000

I receive the following error

keytool error: java.lang.Exception: The -keyalg option must be specified.

Not sure what I need to input for the -keyalg
