Answer 1

You're following the instructions from the master branch but you're using Gerrit 2.13.7. Have you installed the secure-config plugin from master branch or from stable-2.13 one? I saw there's a difference between the master and stable-2.13 instructions in the "How to run" section:
master
Gerrit secure.config properties need to be generated and managed using the Gerrit init wizard. All the passwords entered at init will be stored as encrypted values and then decrypted on-the-fly when needed at runtime.
stable-2.13
This plugin will decode values in secure.config, it will fail if there is an existing secure.config which contains values that are not encrypted. If the values in the current secure.config are not encrypted you will need to either clear out secure.config or back it up by moving it to another file before running this plugin.
See the stable-2.13 instructions here.
