What is a P7R File Type?

When two entities want to verify the identity, one of them can issue a certificate request to another entity, which then responds with a P7R file. The inside key of this file can be used to encrypt the data in such a way that only the owner of the original key can decrypt the data. The P7R applicant can therefore use the embedded key to encrypt his or her own key and return it safely to the transmitter.
