HI Klaus, Thanks for the quick reaction, and thanks for pointing out some existing other smime types. I did a search in RFC 7030, and came up with other necessary smime types. Below the table as required for est-coap draft: (I will change the draft accordingly) - application/pkcs7-mime; smime-type=“server-generated-key”; Encoding = "binary"; ID = TBD1; Reference = RFC5751, RFC7030 - application/pkcs7-mime; smime-type=“certs-only”; Encoding = "binary"; ID = TBD2; Reference = RFC5751 - application/pkcs7-mime; smime-type=“CMC-request”; Encoding = "binary"; ID = TBD3; Reference = RFC5751, RFC5273 - application/pkcs8; smime-type = ---; Encoding = "binary"; ID = TBD4; Reference = RFC5958 - application/csrattrs; smime-type = ---; Encoding = "binary"; ID = TBD5; Reference = RFC7030 - application/pkcs10; smime-type = ---; Encoding = "binary"; ID = TBD6; Reference = RFC5967 I expect the Encoding is orthogonal to the media type and smime type specification.
