5.  Key Usage Bits

   The intended application for the key is indicated in the keyUsage
   certificate extension; see Section 4.2.1.3 of [RFC5280].  If the
   keyUsage extension is present in certificates, then keyEncipherement
   MUST be the only key usage set for certificates that indicate id-alg-
   ml-kem-* in SubjectPublicKeyInfo, (with * being one of 512, 768, or
   1024.)
