So I wouldn't want to remove or parse any of the `leadingData` as it could be binary data in front of them PEM.  
Since this is a byte[] from an InputStream, I think there is an expectation that every byte will be there.  If it was a Reader, it maybe different.  Also if the app is reading `leadingData` by converting into a String, I think that trailing newline is removed.
