Please could you consider adding support for the comparison of signatures between databases. Currently SQL Compare doesn't check for differences between module signatures, please refer to this forum post:

https://forum.red-gate.com/discussion/87404/module-signing-support

The consequence of this is that during deployment by SQL Compare, module signatures will be ignored, therefore causing deployed modules that depend on the signatures to fail during execution.

Additionally, should signatures be removed from a database using a command such as sp_refreshsqlmodule (which implicitly removes signatures), SQL Compare will not identify that the signatures have been removed.
