Introduction The PKCS #12 [RFC7292] format is widely used for interoperable transfer of certificate, key, and other miscellaneous secrets between machines, applications, browsers, etc. Unfortunately, the original specification mandates the use of a specific password based key derivation function, allowing only for change of the underlying message digest function. 2. Rationale Due to security concerns with PBKDF1 and much higher extensibility of PBMAC1, 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 verification. Use of the Kario Expires 5 January 2024 [Page 2] Internet-Draft PBMAC1 in PKCS#12 July 2023 extensible PBMAC1 mechanism also allows for greater flexibility and alignment to different government regulations. As recommended methods for key protection require both encryption and integrity protection, we've decided to amend the PKCS #12 format to support different key derivation functions rather than extending the PKCS #5 by a new field allowing integrity protection. 3. Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 4. Embedding PBMAC1 in PKCS #12 The MacData structure in the PFX object is changed as follows: 1. 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, then the parameters field MUST be present and have the value consistent with PBMAC1-params 2. 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 the PBMAC1 algorithm is used, the macSalt value MUST be ignored, for backwards compatibility it SHOULD NOT be empty 4. if the PBMAC1 algorithm is used, the iteration value MUST be ignored, for backwards compatibility it SHOULD have a non-zero positive value 5. Recommended parameters To provide interoperability between different implementations, all implementations of this specification MUST support the PBKDF2 key derivation function paired with SHA-256 HMAC for both integrity check and as the PBKDF2 pseudorandom function (PRF). It's RECOMMENDED for implementations to support other SHA-2 based HMACs. Implementations MAY use other hash functions, like the SHA-3 famility of hash functions SHA-3 [SHA3]. Implementations MAY use other KDF methods, like the scrypt PBKDF RFC 7914 [RFC7914]. Kario Expires 5 January 2024 [Page 3] Internet-Draft PBMAC1 in PKCS#12 July 2023 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 means that PBMAC1-params specifying SHA-256 HMAC should also include KDF parameters that generate 32 octet long key. In particular, when using the PBKDF2, the implementations MUST include the keyLen field in the encoded PBKDF2-params. Implementations MUST NOT accept PBKDF2 KDF with PBKDF2-params that omit the keyLen field. 6. Deprecated Algorithms While attacks against SHA-1 HMACs are not considered practical [RFC6194] to limit the number of algorithms needed for interoperatbility, implementations of this specification SHOULD NOT use PBKDF2 with the SHA-1 HMAC. Additionally the implementation MUST NOT use any other message digest functions with output of 160 bits or smaller. 7. IANA Considerations This memo includes no request to IANA. 8. Security Considerations Except for use of different key derivation functions, this document doesn't change how the integrity protection on PKCS #12 objects is computed; therefore all the original security considerations from RFC 7292 [RFC7292] apply. Use of PBMAC1 and PBKDF2 is unchanged from RFC 8018 [RFC8018]; therefore all the original security considerations apply. The KDFs generally don't have a lower limit for the generated key size, allowing specifying 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 20 octets. 9. References 9.1.
