A function for calculating a Message Authentication Code (MAC) based on the GOST R 34.11-2012 hash function (see [RFC6986]) with 512-bit output in accordance with [RFC2104]. 4. PFX The transport key container (PFX; see [RFC7292]) is designed for secure storage and data transfer. The scope of this document is to define how the transport key container is used for private key and certificate protection with a password when GOST R 34.10-2012 is applied. 4.1. Structure of PFX In accordance with [RFC7292], the transport key container has the following structure: PFX ::= SEQUENCE { version INTEGER {v3(3)}(v3,...), authSafe ContentInfo, macData MacData OPTIONAL } The fields of the PFX have the following meanings: * version is the syntax version number; the only allowed value for this specification is 3. * authSafe contains the data of type ContentInfo. In the case of password integrity mode, the authSafe.content field has a Data type value and contains a BER-encoded value of the AuthenticatedSafe structure. * macData has a MacData type; in the case of password integrity mode, the macData field should contain information about the algorithm and parameters for password key generation. Integrity control is ensured by using the HMAC_GOSTR3411_2012_512 algorithm: the macData.mac.digestAlgorithm.algorithm field contains the HMAC_GOSTR3411_2012_512 algorithm identifier (see Section 7). When processing a transport key container, this field should be checked first. 4.2. AuthenticatedSafe The AuthenticatedSafe structure is a sequence of ContentInfo values (see [RFC5652]): AuthenticatedSafe ::= SEQUENCE OF ContentInfo -- Data if unencrypted -- EncryptedData if password-encrypted -- EnvelopedData if public key-encrypted 4.2.1. Unencrypted Data If the data is not encrypted, then the content field is the BER- encoded value of the SafeContents structure. The contentType field is set to the id-data type. 4.2.2. Password-Encrypted Data When password integrity mode is used, the data is represented as an EncryptedData structure (see [RFC5652]). The encryption algorithm and parameters have the following values: ContentEncryptionAlgorithmIdentifier ::= SEQUENCE { encryptionAlgorithmOID OBJECT IDENTIFIER, parameters PBES2-params } The PBES2-params type is defined in [RFC9337]. The content should be encrypted according to the encryption algorithm in the PBES2 scheme, as described in [RFC9337]. The following identifier MUST be specified in the EncryptedData.EncryptedContentInfo.contentEncryption Algorithm.encryptionAlgorithmOID field: { iso(1) member-body(2) us(840) rsadsi(113549) pkcs(1) pkcs-5(5) pbes2(13) } The encrypted content is specified in the EncryptedData.EncryptedContentInfo.encryptedContent field. 4.3. SafeContents and SafeBag In accordance with [RFC7292], the SafeContents structure is a sequence of SafeBag: SafeContents ::= SEQUENCE OF SafeBag where SafeBag ::= SEQUENCE { bagId BAG-TYPE.&id ({PKCS12BagSet}) bagValue [0] EXPLICIT BAG-TYPE.&Type({PKCS12BagSet}{@bagId}) bagAttributes SET OF PKCS12Attribute OPTIONAL } The fields of SafeBag have the following meanings: * bagId is an object identifier; it defines the type of object. * bagValue is the value of an object. * bagAttributes contains the users' names, the key identifiers, and other additional information. This field is optional. See [RFC7292], Section 4.2 for the different bag types. This document describes the two object types of the SafeBag structure: 1. pkcs8ShroudedKeyBag 2. certBag When password integrity mode is used, the private key has the following structure: pkcs8ShroudedKeyBag BAG-TYPE ::= { PKCS8ShroudedKeyBag IDENTIFIED BY {bagtypes 2} } The bagValue field contains the key and information about the key, in encrypted form, in the EncryptedPrivateKeyInfo structure. A certBag contains a certificate of a certain type. Object identifiers are used to distinguish between different certificate types. certBag BAG-TYPE ::= { CertBag IDENTIFIED BY { bagtypes 3 } } If the certificate is not encrypted, the CertBag structure is placed in the Data structure (see [RFC5652]). If the certificate is encrypted, the CertBag structure is placed in the EncryptedData structure (see [RFC5652]). 5. GOST R 34.10-2012 Key Representation This section describes the GOST R 34.10-2012 private key representation for asymmetric key pairs. Masked keys should be used to ensure that private keys are protected from leaking through side channels when reading and performing operations with keys. 5.1. Masking GOST R 34.10-2012 Keys The masking algorithm is defined by the basic cryptographic transformation operation of the algorithm: multiplication in the F_q field for GOST R 34.10-2012 keys. Let M_1, M_2, ..., M_k be a sequence of k masks. Let M_i() denote the operation of applying the i-th mask and M_i^-1() denote the operation of removing the i-th mask, 1 <= i <= k. Let K be a key. The masked key K_M is obtained by applying the masking operation k times: K_M = M_k (...(M_2(M_1(K)...). Unmasking is performed by applying the removal operation k times, but in reverse order: K = M_1^-1(...(M_(k-1)^-1(M_k^-1(K_M))...). The masked key is represented as the sequence I = K_M||M_1||M_2||...||M_k. Let the key K be n bits in length; then, the sequence I is represented in memory as a sequence of (k + 1)*n bits. I is represented in little-endian format. It is possible to use an unmasked private key (i.e., k = 0, K_M = K). The masking operation is the multiplication of the key by the inverse of the mask: K_M = K * M^-1 mod Q, where the Q value is taken from the key parameters. The operation of removing the mask is the multiplication of the masked key by the mask: K = K_M * M mod Q. The public key is specified by a pair of coordinates (x, y) as defined in GOST R 34.10-2012, presented in the following format: * a public key corresponding to the GOST R 34.10-2012 algorithm with a key length of 256 bits has the GostR3410-2012-256-PublicKey representation. It is specified by a 64-byte string, where the first 32 bytes contain the little-endian representation of the x coordinate and the last 32 bytes contain the little-endian representation of the y coordinate. * a public key corresponding to the GOST R 34.10-2012 algorithm with a key length of 512 bits has the GostR3410-2012-512-PublicKey representation. It is specified by a 128-byte string, where the first 64 bytes contain the little-endian representation of the x coordinate and the last 64 bytes contain the little-endian representation of the y coordinate. The public keys GostR3410-2012-256-PublicKey and GostR3410-2012-512-PublicKey MUST be DER encoded as an octet string in accordance with Section 4.3 of [RFC9215]: GostR3410-2012-256-PublicKey ::= OCTET STRING (64), GostR3410-2012-512-PublicKey ::= OCTET STRING (128). 5.2. KeyBag Structure for GOST R 34.10-2012 Key In accordance with [RFC7292], a KeyBag is defined as information about a private key represented as the PrivateKeyInfo structure: KeyBag := PrivateKeyInfo In accordance with [RFC5958], information about a private key is presented in the following form: PrivateKeyInfo := OneAsymmetricKey 5.3. OneAsymmetricKey Structure In accordance with [RFC5958], OneAsymmetricKey has the following structure: OneAsymmetricKey::= SEQUENCE { version Version, privateKeyAlgorithm PrivateKeyAlgorithmIdentifier, privateKey PrivateKey, attributes [0] Attributes OPTIONAL, ..., [[2:publicKey [1] PublicKey OPTIONAL]], ... } Version ::= INTEGER { v1(0), v2(1) } (v1, ..., v2) PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier PrivateKey ::= OCTET STRING PublicKey ::= BIT STRING Attributes ::= SET OF Attribute The fields have the following meanings: * version identifies the version of OneAsymmetricKey. If publicKey is present, then version is set to 2; else, version is set to 1. * privateKeyAlgorithm identifies the private key algorithm and optionally contains parameters associated with the asymmetric key pair. For GOST R 34.10-2012 private keys, the identifiers of the corresponding public keys are used; they are defined in [RFC9215]. The use of identifiers and public key parameters is defined in [RFC9215]. * privateKey is an OCTET STRING that contains the value of the masked private key I. * attributes are optional. They contain information corresponding to the public key (e.g., certificates). * publicKey contains the value of the public key GostR3410-2012-256-PublicKey or GostR3410-2012-512-PublicKey encoded in a BIT STRING. This field is optional. 5.4. EncryptedPrivateKeyInfo Structure for GOST R 34.10-2012 Key In accordance with [RFC7292], the encrypted information regarding the private key is defined as the PKCS8ShroudedKeyBag structure: PKCS8ShroudedKeyBag::= EncryptedPrivateKeyInfo In accordance with [RFC5958], EncryptedPrivateKeyInfo has the following structure: EncryptedPrivateKeyInfo ::= SEQUENCE { encryptionAlgorithm EncryptionAlgorithmIdentifier, encryptedData EncryptedData } EncryptionAlgorithmIdentifier ::= AlgorithmIdentifier EncryptedData ::= OCTET STRING The fields have the following meanings: * encryptionAlgorithm identifies the algorithm under which the private key information is encrypted. Encryption MUST use the PBES2 scheme. The algorithm and parameters of this scheme are presented in [RFC9337]. * encryptedData is the DER-encoded PrivateKeyInfo structure. 6. GOST R 34.10-2012 Certificate Representation In accordance with [RFC7292], a CertBag is defined as information about a certificate and has the following structure: CertBag ::= SEQUENCE { certId BAG-TYPE.&id ({CertTypes}), certValue [0] EXPLICIT BAG-TYPE.&Type ({CertTypes}{@certId}) } The fields have the following meanings: * certId identifies the type of certificate. * certValue contains the certificate. 7. Security Mechanisms Let the sender and receiver have a previously agreed-upon password P. The sender generates a password key using the PBKDF2 algorithm in accordance with [RFC9337] and uses it to encrypt the transmitted private key. The recipient independently generates a password key using the same PBKDF2 diversification algorithm in accordance with [RFC9337] and uses it to extract the private key from the PFX. The same password P is used to encrypt different sections of the PFX using a different random initializing value S with a length of 8 to 32 bytes, where S and P are the input parameters of the PBKDF2 function. The password MUST be encoded as a Unicode UTF-8 string and fed into the PBKDF2 algorithm as a P parameter. The integrity of the PFX is ensured by using the HMAC_GOSTR3411_2012_512 algorithm in accordance with [RFC7836]. To check the integrity of the PFX with the HMAC_GOSTR3411_2012_512 algorithm, the key for this algorithm is also generated by using the PBKDF2 algorithm in accordance with [RFC9337], with the same value for the P parameter and a different initializing value S with a length of 8 to 32 bytes. The dkLen parameter for the PBKDF2 algorithm is set to 96 bytes. The key for the HMAC_GOSTR3411_2012_512 algorithm must be the last 32 bytes of the 96-byte sequence generated by the PBKDF2 algorithm. The PBKDF2 algorithm parameters S and c are saved in the macData.Salt and macData.iterations fields, respectively. The HMAC_GOSTR3411_2012_512 function is calculated from the content field of the authSafe structure field. The authSafe structure field is a PFX structure field. The value of the calculated checksum is saved in the macData.mac.digest field. The macData.mac.digestAlgorithm.algorithm field contains the following algorithm identifier: id-tc26-gost3411-12-512 :: = { iso(1) member-body(2) ru(643) rosstandart(7) tc26(1) algorithms (1) digest(2) gost3411-2012-512(3) } The macData.mac.digestAlgorithm.parameters field isn't used and should be omitted. 8. Security Considerations The masked keys SHOULD be used to ensure that private keys are protected from leaking through side channels when reading and performing operations with keys. Applications MUST use unique values for ukm and S in the PBKDF2 algorithm. It is RECOMMENDED that parameter S consist of at least 32 octets of pseudorandom data in order to reduce the probability of collisions of keys generated from the same password. The password MUST be encoded as a Unicode UTF-8 string and fed into the PBKDF2 algorithm as a P parameter. For more information, see [RFC9337]. Encryption MUST use the PBES2 scheme to encrypt private keys. Public keys MUST be DER encoded as an octet string in accordance with [RFC9215]. Passwords SHOULD be stored in a secure way. For information on security considerations for generating transport key containers, see [RFC7292]. 9. IANA Considerations This document has no IANA actions. 10.
