How to re codesign iPhone app binary?

I'd like to send a binary to a client without the source code. How can here sign the app for distribution on it's own name without recompiling everything (since he does not have the source code) I'm not talking about adhoc开发者_高级运维 distribution. I've tried to codesign -f with another distribution profile but itunes connect refuses it.

The client needs to send you his distribution certificate and personnal certificate with his public key, matching his iPhone developer identity, so you can compile the app with his informations.
