Status: Held for Document Update

Section: 4.1

Original Text
-------------
   Certificate  ::=  SEQUENCE  {
        tbsCertificate       TBSCertificate,
        signatureAlgorithm   AlgorithmIdentifier,
        signatureValue       BIT STRING  }

Corrected Text
--------------
   Certificate  ::=  SEQUENCE  {
        tbsCertificate       TBSCertificate,
        signatureAlgorithm   AlgorithmIdentifier,
        signature            BIT STRING  }

Notes
-----
The definition in section 4.1 disagrees with the definition in appendix A.1 (page 116) on whether the name of the field containing the signature is "signatureValue" or "signature". This error appears in RFC 3280 and RFC 2459 as well.

The versions of X.509 in force when RFCs 2459, 3280, and 5280 were published use neither of those names. (Those versions of X.509 considered a signature to be an encrypted hash and called the field "encrypted".) The current version, ITU-T X.509 (10/2019), defines this field to be "signature" in section 6.2.1. (X.509 defines the Certificate type using a component type of SIGNATURE, which has two fields named "algorithmIdentifier" and "signature".)

In addition to changing the field name in the definition of the Certificate type in section 4.1, the title and text of subsection 4.1.1.3 should be updated to replace "signatureValue" with "signature".

Verifier note:  Hold for document update to avoid changes that potentially break ASN.1
