                                 Syntax
                   draft-ietf-lamps-pkcs12-pbmac1-08

Abstract

   This document specifies additions and amendments to RFCs 7292 and
   8018.  It defines a way to use the Password Based Password-Based Message
   Authentication Code 1, 1 (PBMAC1), defined in RFC 8018, inside the PKCS
   #12 syntax.  The purpose of this specification is to permit the use
   of more modern Password-Based Key Derivation Functions (PBKDFs) and
   allow for regulatory compliance.

1.  Introduction

   The PKCS #12 [RFC7292] format [RFC7292] is widely used for the interoperable
   transfer of certificate, key, and other miscellaneous secrets between
   machines, applications, browsers, etc.  Unfortunately, the original
   specification [RFC7292]
   mandates the use of a PKCS #12 specific password based password-based key derivation function, the PBKDF1, allowing
   function that only allows for change of the underlying message digest
   function.

2.  Rationale

   Due to security concerns with PBKDF1 the key derivation function from
   [RFC7292] and the much higher extensibility of PBMAC1 [RFC8018], we
   propose the use of PBMAC1 for integrity protection of PKCS #12
   structures.  The new syntax is designed to allow legacy applications
   to still be able to decrypt the key material, even if they are unable
   to interpret the new integrity protection, provided that they can
   ignore failures in MAC Message Authentication Code (MAC) verification.
   This change allows for the use of PBKDF2 [RFC8018] or scrypt PBKDFs
   [RFC7914] KDFs for derivation of MAC keys and future extensibility.  Use
   of the extensible PBMAC1 mechanism also allows for greater
   flexibility and alignment to with different government regulations, for
   example, in environments where PBKDF2 is the only allowed password-based password-
   based key derivation function.

   As the recommended methods for key protection require both encryption
   and integrity protection, we've we decided to amend the PKCS #12 format to
   support different key derivation functions rather than extending the
   PKCS #5 format by a new field allowing that allows integrity protection.

   We have included an ASN.1 module [x680] [x681][x682][x683] [x681] [x682] [x683] [x690] that
   can be combined with the ASN.1 module modules in [RFC7292] and [RFC8018] to
   incorporate additional MAC algorithms.

3.  Requirements Language

   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] [RFC2119] [RFC8174] when, and only when, they appear in all
   capitabls,
   capitals, as shown here.

4.  Embedding PBMAC1 in PKCS #12

   The MacData structure in the PFX object, as described in bullet item #3 in
   section
   Section 4 of RFC 7292 [RFC7292], is updated to include this
   additional the following
   PBMAC1-specific guidance:

   1.  the

   |  a.  The id-PBMAC1 object identifier is permitted as a valid type
   |      for the DigestAlgorithmIdentifier inside the DigestInfo
   |      object.  If the algorithm field of the
   |      DigestAlgorithmIdentifier is id-
       PBMAC1, id-PBMAC1, then the parameters
   |      field MUST be present and have the a value consistent with
   |      PBMAC1-params

   2.  if parameters.
   |
   |  b.  If the PBMAC1 algorithm is used, the digest value of the
   |      DigestInfo object MUST be the result of the PBMAC1 calculation
   |      over the authSafe field using the PBMAC1-params parameters
   3.  if parameters.
   |
   |  c.  If the PBMAC1 algorithm is used, the macSalt value MUST be
       ignored, for
   |      ignored.  For backwards compatibility compatibility, it SHOULD NOT be empty

   4.  if empty.
   |
   |  d.  If the PBMAC1 algorithm is used, the iterations value MUST be
       ignored, for
   |      ignored.  For backwards compatibility compatibility, it SHOULD have a non-zero non-
   |      zero positive value value.

5.  Recommended parameters Parameters

   To provide interoperability between different implementations, all
   implementations of this specification MUST support the PBKDF2 key
   derivation function paired with SHA-256 HMAC [SHA2] [RFC2104] for
   both integrity check and as the PBKDF2 pseudorandom function (PRF).
   It's RECOMMENDED for implementations to support other SHA-2 based SHA-2-based
   HMACs.  Implementations MAY use other hash functions, like the SHA-3
   family of hash functions SHA-3 [SHA3].  Implementations MAY use other KDF
   methods, like the scrypt PBKDF [RFC7914].

   The length of the key generated by the used KDF MUST be encoded
   explicitly in the parameters field and SHOULD be the same size as the
   HMAC function output size.  That  This means that PBMAC1-params specifying
   SHA-256 HMAC should also include KDF parameters that generate 32
   octet long a
   32-octet key.  In particular, when using the PBKDF2, the implementations
   MUST include the keyLen keyLength field in the encoded PBKDF2-params.
   Implementations MUST NOT accept PBKDF2 KDF with PBKDF2-params that
   omit the keyLen keyLength field.

6.  Password encoding Encoding

   As documented in Appendix B.1 of RFC 7292 [RFC7292] [RFC7292], the handling of password
   encoding in the underlying standards is underspecified.  However,
   just as with PBES1 and PBES2 when used in the context of
   PKCS#12 PKCS #12
   objects, all passwords used with PBMAC1 MUST be created from
   BMPStrings with a NULL terminator.

7.  Deprecated Algorithms

   While attacks against SHA-1 HMACs are not considered practical
   [RFC6194] to limit the number of algorithms needed for
   interoperatbility,
   interoperability, implementations of this specification SHOULD NOT
   use PBKDF2 with the SHA-1 HMAC.  Additionally the implementation  In addition, implementations MUST
   NOT use any other message digest functions with an output of 160 bits
   or
   smaller. less.

8.  IANA Considerations

   IANA is requested to assign an has registered the following object identifier from in the SMI "SMI
   Security for S/MIME Module Identifier registry (1.2.840.113549.1.9.16.0)"
   registry.  See Appendix B for the ASN.1 module
   found in Appendix B. module.

9.  Security Considerations

   Except for the use of different key derivation functions, this
   document doesn't change how the integrity protection on PKCS #12
   objects is computed; therefore therefore, all the original security considerations from RFC
   7292
   [RFC7292] apply.

   Use of PBMAC1 and PBKDF2 is unchanged from RFC 8018 [RFC8018];
   therefore therefore, all
   the original security considerations from [RFC8018] apply.

   The KDFs generally don't have a lower limit for the generated key
   size, allowing specifying the specification of very small key sizes (of 1
   octet), which can facilitate brute-force attacks on the HMAC.  Since
   the KDF parameters are not cryptographically protected and HMACs
   accept arbitrary key sizes, implementations MAY refuse to process KDF
   parameters that specify small key output sizes or weak parameters.
   It's RECOMMENDED to reject any KDF parameters that specify key
   lengths below less than 20 octets.

Appendix B.  ASN.1 Module

   Note to RFC Editor: please change the TBD value below with the value
   assigned by IANA

   types, values, and object sets for this specification.  It does so by
   providing an ASN.1 module called PKCS12-PBMAC1-2023.

   Combine this module with the PKCS-12 ASN.1 module found in Appendix D
   of [RFC7292] and the pkcs5v2-1 ASN.1 module in Appendix C of
   [RFC8018] to add SHA-2 based SHA-2-based HMACs by replacing the PBKDF2-PRFs class found therein.
