Overview#
SignatureValue is a
Basic Certificate Field defined in
RFC 5280 section 4.1.1.3 contains a digital signature computed upon the
ASN.1 DER encoded
TBSCertificate. The
ASN.1 DER encoded
TBSCertificate is used as the input to the
SignatureAlgorithm function. This signature value is encoded as a
BIT STRING and included in the signature field. The details of this process are specified for each of the
algorithms listed in
RFC 3279,
RFC 4055, and
RFC 4491.By generating this signature, a
CA certifies the validity of the information in the
TBSCertificate field. In particular, the
CA certifies the binding between the
Public Key material and the
Certificate Subject of the
certificate.
