Appendix A – Views and Functions ReferenceUSE HomeLending;GOSELECT Cert_ID('MySelfSignedCert');GOListing A-10: Syntax of Cert_ID.CertPropertyA certification contains properties that are valuable for reference. Through thisfunction the following properties can be returned:• Expiry_Date: This is the date and time that the certificate is nolonger available for use.• Start_Date: This is the date and time that the certificate becomesavailable for use.• Issuer_Name: The X.509 standard identifies the issuer as the entitythat has verified the information within the certificate.• Cert_Serial_Number: The X.509 standard defines this number asthe value that uniquely identifies the certificate.• Subject: The X.509 standard defines the subject as the person orentity that is identified with the certificate.• Sid: The binary representation of the login security identifier for thecertificate.• String_Sid: The nvarchar representation of the login securityidentifier for the certificate.USE HomeLending;GOSELECT CertProperty(Cert_ID('MySelfSignedCert'),'Expiry_Date');GOListing A-11: Syntax of CertProperty.DecryptByAsymKeyThis function is used to decrypt data that has been encrypted with anasymmetric key.
