Can bidding ca and social security ca be used?

Bidding CA is an electronic certificate, which is used for digital signature and encrypted transmission in the bidding process. It is safe, reliable and confidential, and it is an important means to realize the electronization of bidding activities. Social Security CA is a digital certificate for online social security business, which is issued and managed by the social security department and has the characteristics of safety, reliability and confidentiality.

Because the bidding CA and social security CA are issued and managed by different institutions, their certificate formats, keys and other information are different, so they cannot be used. If you need to use these two certificates, you need to apply and apply separately.
