This is an OPS-DIR review of Using Curve25519 and Curve448 in PKIX (draft-ietf-curdle-pkix-newcurves-00) The document merely assigns ASN.1 Object Identifiers for elliptic curves 25519 and 448, with and without pre-hashing. Documents, such as this one, which merely assign ASN.1 Object Identifiers do not have any operation concerns, and I found none in this document. I note that I do not see a need for the reference to RFC 2119. I did find the document clear and concise. Scott
