Is it possible in Julia for the developer to encrypt a package (registered or unregistered) in order that the source code is not open to the user but can be used by the user?

I do not think that this is possible. There was a commercial Julia compiler announced recently that can compile a subset of the Julia language. Perhaps this compiler could make this possible.

I think also compiling with `PackageCompiler` has the option to remove the source.
