Java store and read byte array from property file yaml

Chry007 :

I am working on an application that reads data from a database. There are already encrypted entries in the DB. I have the key as a byte array and want to load it from a yaml file.

Is there a way i can populate an array like this

private static final byte[] iv = { 13, -11, -88, 20, -110, 113, -2, -8, -15, -99, -23, -10, -10, -74, 1, 11 }

Directly from a yaml file?

yaml file:

iv: 13,-11,-88

Since I cannot autowire the class where I need to use the key, i cannot use @value annotation (from my understanding). So I was looking to use a util class like so:

public static byte[] getKeyFor(Class type) {
    return context.getEnvironment().getProperty("iv");
}

Below should work:

application.yml:

iv: 12,32,12,32

In the class where you want the values, bind it like below:

@Value("${iv}") byte[] iv;
