The sequence TBSCertificate contains information associated with the subject of the certificate and the CA that issued it.

RFC5280 definition:

  TBSCertificate  ::=  SEQUENCE  {
       version         [0]  EXPLICIT Version DEFAULT v1,
       serialNumber         CertificateSerialNumber,
       signature            AlgorithmIdentifier,
       issuer               Name,
       validity             Validity,
       subject              Name,
       subjectPublicKeyInfo SubjectPublicKeyInfo,
       issuerUniqueID  [1]  IMPLICIT UniqueIdentifier OPTIONAL,
                            -- If present, version MUST be v2 or v3
       subjectUniqueID [2]  IMPLICIT UniqueIdentifier OPTIONAL,
                            -- If present, version MUST be v2 or v3
       extensions      [3]  EXPLICIT Extensions OPTIONAL
                            -- If present, version MUST be v3
       }
