Document: draft-gutmann-testkeys-04 Reviewer: Linda Dunbar Review Date: 2023-07-17 IETF LC End Date: 2023-07-13 IESG Telechat date: Not scheduled for a telechat Summary: The draft specifies a set of PKC test keys for applications to be aware that those are for testing purposes only and have no security association. Major issues: It needs to be made clear of the consequences if those PKC test keys are not published. Recommend adding a paragraph to describe behaviors when those PKC test keys are not specified. Minor issues: None Nits/editorial comments: Thank you, Linda Dunbar
