I have created a stored procedure in the msdb that will basically start a job and wait for completion. I have implemented the certificate signed stored procedure in one database successfully, but would now like to incorporate it into a second database. I was thinking I would be able to use the same certificate to make this happen (create in second database from file).

This does not seem to be the case though. Doing a select on sys.certificates in the second database shows NA for pvt_key_encryption_type and NO_PRIVATE_KEY for pvt_key_encryption_type_desc. I receive the following error when trying to sign the stored procedure in the second database from this certificate

Msg 15556, Level 16, State 1, Line 1

Cannot decrypt or encrypt using the specified certificate, either because it has no private key or because the password provided for the private key is incorrect.

I was wondering if this is possible. And if so if there are any reasons not to do this.

I could see this expanding to other databases in the future and would like to use one certificate (since everything will be targeting the same stored procedure in the msdb database) instead of having to create numerous certificates, logins, users, etc.

Any advise/information is much appreciated.

Thanks,

Sam
