1. Introduction
This document updates the cryptographic algorithm requirements for
the Password-Based Message Authentication Code (MAC) in the Internet
X.509 Public Key Infrastructure Certificate Request Message Format
(CRMF) [RFC4211]. The algorithms specified in [RFC4211] were
appropriate in 2005; however, these algorithms are no longer
considered the best choices. This update specifies algorithms that
are more appropriate today.
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
3. Signature Key POP
Section 4.1 of [RFC4211] specifies the Proof-of-Possession (POP)
processing. This section is updated to explicitly allow the use of
the PBMAC1 algorithm presented in Section 7.1 of [RFC8018].
OLD:
algId identifies the algorithm used to compute the MAC value. All
implementations MUST support id-PasswordBasedMAC. The details on
this algorithm are presented in section 4.4
