Quizplus · Accepted Answer

The extension described with permitted subtrees and excluded subtrees is Name constraints, which is a critical extension applicable only for CA certificates. Policy mappings and Policy constraints are also extensions for CA certificates, but they do not have the specific fields of permitted subtrees and excluded subtrees. Basic constraints is an extension for both CA and end-entity certificates, but it does not have the fields described in the question.
