But they kept secret the internals of the ME for ~10 years.

You can only ...


What you want is impossible; there's no "tool" that can do that. When you encrypt your file, and then only someone in ownership of the key can get the contents – that's the point of encryption. Since you still want to use it, you, however, need to supply that key to the device that will use your image. Can't include the key anywhere unencryptedly ...
