    @neykov How about overloading `readPem` to take a byte array? It looks like that is the
way it is used anyway.
    And for the tests that call it, I wonder if we should add `byte[] ResourceUtils.getResourceAsBytes(String
url)`. Again it feels like many callers of the existing `getResourceFromUrl` either want it
as a string or as bytes.
