NEW: ... the id-pkix-ocsp-basic OID. 3) s3.2.1: use elements instead of SingleResponses OLD: two SingleResponses in a BasicOCSPResponse NEW: two SingleResponse elements in a BasicOCSPResponse OLD: the CertID of one of the SingleResponses uses NEW: the CertID of one of the SingleResponse structures uses 4) s3.2.1: Refer to correct extension structure OLD: The responder MAY include the singleResponse.singleResponse extensions structure. NEW: The responder MAY include the SingleResponse.SingleExtensions extensions structure. 5) s3.2.3: Do we still extend the definition of unauthorized? In 5019, the definition of unauthorized was extended. RFC 6960 was updated to match the definitions in RFC 5019. So can we drop this bit of text: As such, this profile extends the [RFC6960] definition of "unauthorized" as follows: The response "unauthorized" is returned in cases where the client is not authorized to make this query to this responder or the responder is not capable of responding authoritatively. 6) s8.2: rename title OLD: 8.2.

On Jan 16, 2026, at 13:46, [email protected] <mailto:[email protected]> wrote: Authors, While reviewing this document during AUTH48, please resolve (as necessary) the following questions, which are also in the source file. 1) <!--[rfced] Please note the title of the document has been updated as follows. Abbreviations have been expanded per Section 3.6 of RFC 7322 ("RFC Style Guide"). Please review. Original: Updates to Lightweight OCSP Profile for High Volume Environments Current: Updates to the Lightweight Online Certificate Status Protocol (OCSP) Profile for High Volume Environments Because this document will obsolete RFC 5019 (rather than update it), we suggest changing the title and abbreviated title as follows. Is this acceptable? Original: Updates to Lightweight OCSP Profile for High Volume Environments Perhaps (same title as RFC 5019): The Lightweight Online Certificate Status Protocol (OCSP) Profile for High-Volume Environments Similarly, may the abbreviated title (which appears in the running header of the PDF) be updated as follows? Original: Lightweight OCSP Profile Update Perhaps: Lightweight OCSP Profile --> Yes, since we’re obsoleting it there’s no need for the “Updates to” / “Update” words. 2) <!-- [rfced] Please insert any keywords (beyond those that appear in the title) for use on https://www.rfc-editor.org/search. --> Revocation 3) <!--[rfced] FYI, we changed "RECOMMENDS" to "is RECOMMENDED by" (2 instances), as "RECOMMENDED" is the defined keyword from BCP 14. This update allows using the <bcp14> element without warnings. We realize the original text matches RFC 5019. For example: Original: Clients SHOULD NOT include the requestExtensions structure. If a requestExtensions structure is included, this profile RECOMMENDS that it contain only the nonce extension (id-pkix-ocsp-nonce). Current: Clients SHOULD NOT include the requestExtensions structure. If a requestExtensions structure is included, it is RECOMMENDED by this profile that the structure contain only the nonce extension (id-pkix- ocsp-nonce). --> WFM 4) <!--[rfced] Is this line within the sourcecode in Section 3.2.1 intended to be a comment within the sourcecode, or should it be taken out of the sourcecode? (Note: This line exceeded the 72-character limit so we included a line break within the sourcecode.) Original: The value for response SHALL be the DER encoding of BasicOCSPResponse. --> This sentence should be taken out of the source code, so I guess that means there’s two blocks of source code. 5) <!--[rfced] May we update this sentence as follows to clarify that the protocol in [RFC5019] is backward compatible, rather than the RFC itself? Original: Older responders which provide backward compatibility with [RFC5019] MAY use the byName field to represent the ResponderID, but should transition to using the byKey field as soon as practical. Perhaps: Older responders that provide backward compatibility with the protocol defined in [RFC5019] MAY use the byName field to represent the ResponderID but should transition to using the byKey field as soon as practical. --> Yes 6) <!--[rfced] We are having some trouble understanding how "server name and base64-encoded OCSPRequest structure" fits into the sentence below. Please review and let us know the sentence may be updated for clarity. Original: When sending requests that are less than or equal to 255 bytes in total (after encoding) including the scheme and delimiters (http://), server name and base64-encoded OCSPRequest structure, clients MUST use the GET method (to enable OCSP response caching). Perhaps: When sending requests that are less than or equal to 255 bytes in total (after encoding), including the scheme and delimiters (http://), server name, and base64-encoded OCSPRequest structure, clients MUST use the GET method (to enable OCSP response caching). --> I think that’s right. The 255 bytes needs to include everything that is listed there. 7) <!--[rfced] Should "productedAt" be "producedAt" (no 't')? Even though RFC 5019 contains one instance of "productedAt", it contains seven instances of "producedAt". We note that other RFCs also use "producedAt" (e.g., RFCs 9654, 6960, 5912). Original: productedAt = March 19, 2023 01:00:00 GMT Suggested: producedAt = March 19, 2023 01:00:00 GMT --> GREAT CATCH! Definitely needs to be “producedAt”! 8) <!--[rfced] May this sentence be updated as follows to avoid citing RFC 9846 twice? Original: This functionality has been specified as an extension to the TLS [I-D.ietf-tls-rfc8446bis] protocol in Section 4.4.2 of [I-D.ietf-tls-rfc8446bis], but can be applied to any client-server protocol. Current: This functionality has been specified as an extension to the TLS protocol [RFC9846] in Section 4.4.2 of [RFC9846] but can be applied to any client-server protocol. Option A: This functionality has been specified as an extension to the TLS protocol in Section 4.4.2 of [RFC9846] but can be applied to any client-server protocol. Option B: In Section 4.4.2 of [RFC9846], this functionality has been specified as an extension to the TLS protocol, but it can be applied to any client-server protocol. --> I prefer option A. 9) <!-- [rfced] We were unable to find a document directly matching the title provided in the original reference.

Please review and let us know if any updates are needed. Original: Future versions of the OCSP protocol may provide a way for the client to know whether the responder supports nonces or does not support nonces. ... The authors of this version of the document wish to thank Alex Deacon and Ryan Hurst for their work to produce the original version of the lightweight profile for the OCSP protocol. --> Yes please drop the extra “protocol” where appropriate. 12) <!--[rfced] Abbreviations a) Both the expansion and the acronym for the following term are used throughout the document. Would you like to update to using the expansion upon first usage and the acronym for the rest of the document? certification authority (CA) I am happy with that. b) We note that "AIA" has been expanded two different ways in the document. Please review and let us know which version should be used for consistency. authorityInfoAccess (AIA) vs. authorityInformationAccess (AIA) --> So this is a bit weird maybe: s3.2.2: OLD: authorityInfoAccess (AIA) extension nor cRLDistributionPoints (CRLDP) extension NEW: Authority Information Access (AIA) extension nor CRL Distribution Points (CRLDP) extension S4.1: OLD: authorityInfoAccess extension NEW: AIA extension OLD: authorityInformationAccess (AIA) extension cRLDistributionPoints extension NEW: AIA extension CRLDP extension 13) <!-- [rfced] Please review the "Inclusive Language" portion of the online Style Guide <https://www.rfc-editor.org/styleguide/part2/#inclusive_language> and let us know if any changes are needed.
