!!! Overview
[{$pagename}] 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].
