RFC 5990: Use of the RSA-KEM Key Transport Algorithm in the Cryptographic Message Syntax (CMS)

This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 9690.

Current version: RFC 9690 — Use of the RSA-KEM Algorithm in the Cryptographic Message Syntax (CMS)

In plain English — editorial summary, not part of the RFC

The RSA-KEM Key Transport Algorithm is a one-pass (store-and-forward) mechanism for transporting keying data to a recipient using the recipient's RSA public key. ("KEM" stands for "key encapsulation mechanism".) This document specifies the conventions for using the RSA-KEM Key Transport Algorithm with the Cryptographic Message Syntax (CMS). The ASN.1 syntax is aligned with an expected forthcoming change to American National Standard (ANS) X9.44.
