Codesign No identity found

Question

I am trying to use Codesign in the Terminal like follows:

codesign -f -s "3rd Party Mac Developer Application: asdf" -v "My App.app"

But I keep getting this error:

3rd Party Mac Developer Application: asdf: no identity found

Any ideas? Basically, codesign cannot "see" this certificate. But, no matter how I type it out, I get the same error. I tried the following:

codesign -f -s "3rd Party Mac Developer Application: asdf" -v "My App.app"
codesign -f -s 3rd Party Mac Developer Application: asdf -v "My App.app"
codesign -f -s 3rd\ Party\ Mac\ Developer\ Application:\ asdf -v "My App.app"
codesign -f -s asdf -v "My App.app"
codesign -f -s "asdf" -v "My App.app"
codesign -f -s Application -v "My App.app"

Specifically, I am trying to get my app into the Mac App Store. Is this a problem with provisioning or something? I feel like I've tried everything

Answer 1

I re-created the certificates and this solved the problem. The reason that I posted this question is because I had re-created the certificates before, to no avail.

However, the '3rd Party Mac Developer Application: asdf' certificate was missing the private key, for some reason.
