Is there a difference related to "hackable" between this two ways of signing a message:
In terms of hacking, I wouldn't target a hash-algo, I'd target the assembly that does the check in your application.

In terms of usability; you can calculate a hash, and recalculate it to verify that the target is not changed. If you encrypt it after hashing, then I no langer can recalculate the hash, and I can no longer verify that the content hasn't changed.
