4. PFX

The transport key container (PFX) is designed for secure storage and data transfer that does not contain state secrets. The scope of this document is to use the transport key container to protect private keys and certificates by password.

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 PFX have the following meanings:

  • version is the syntax version number;
  • authSafe contains the data of type ContentInfo. In the case of password integrity mode the content field has a Data type and contains a BER-encoded value of AuthenticatedSafe structure;
  • macData has a MacData type and in the case of password integrity mode the macData field should contain the information about algorithm and parameters for a password key generation. The integrity control is ensured by using the HMAC_GOSTR3411_2012_512 algorithm. 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

In the case of password integrity mode the data is represented as EncryptedData structure. The EncryptedData structure in ASN.1 format is presented according to [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, described in [RFC9337]. The following identifier must be specified in EncryptedData.EncryptedContentInfo.contentEncryptionAlgorithm.encryptionAlgorithmOID field:

{
    iso(1) member-body(2) us(840) rsadsi(113549)
    pkcs(1) pkcs-5(5) pbes2(13)
}

The encrypted content is specified in 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

In accordance with [RFC7292] the SafeBag structure holds one piece of information: keys, certificates, crls, which is identified by an object identifier.

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 keys identifiers and other additional information. It is optional.

This document describes the 2 object types of SafeBag structure:

  • pkcs8ShroudedKeyBag,
  • certBag.

In the case of password integrity mode the private key has the following structure:

pkcs8ShroudedKeyBag BAG-TYPE ::=
{
    PKCS8ShroudedKeyBag IDENTIFIED BY {bagtypes 2}
}

The bagValue field contains the key and information about it in the 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 keys representation for asymmetric key pairs. The masked keys should be used to ensure the protection of private keys from leaks through the 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 be a sequence of k masks M1, M2, ..., Mk. Let Mi() denote the operation of imposing the i-th mask and Mi-1() denote the operation of removing the i-th mask, 1 <= i <= k. Let be a key K. The masked key KM is obtained by applying the masking operation k times:

  • KM = MK (...(M2(M1(K)...).

Unmasking is performed by applying the removing operation k times, but in reverse order:

  • K = M1-1(...(Mk-1-1(Mk-1(KM))...).

The masked key is represented as the sequence

  • I = KM||M1||M2||...||Mkt.

Let the key K have n binary bits, then the sequence I is represented in the memory as a (k + 1)*n-binary bit sequence. The I sequence is represented in little-endian format. It is possible to use an unmasked private key (i.e., k = 0, KM = K). The masking operation is the multiplication of the key by the inverse of the mask: KM = 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 = KM * M mod Q. The public key is specified by a pair of coordinates (x, y) 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 [RFC9215] (section 4.3):

  • 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 a following structure PrivateKeyInfo:

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] the 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 v2 else version is set to v1.
  • 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 presented in the [RFC9215]. The use of identifiers and public key parameters is presented in the [RFC9215].
  • privateKey is an OCTET STRING that contains the value of the masked private key I.
  • attributes are OPTIONAL. It contains 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. It is an optional field.

5.4. EncryptedPrivateKeyInfo structure for GOST R 34.10–2012 key

In accordance with [RFC7292] the encrypted information of the private key is presented as the PKCS8ShroudedKeyBag structure:

PKCS8ShroudedKeyBag::= EncryptedPrivateKeyInfo

In accordance with [RFC5958] the 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 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 represented as the following structure:

CertBag ::= SEQUENCE
{
    certId                  BAG-TYPE.id ({CertTypes}),
    certValue [0] EXPLICIT  BAG-TYPE.Type ({CertTypes}{@certId})
}

The fields have the following meanings:

7. Security Mechanisms

Let the sender and receiver have a pre-agreed 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, but 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 in Unicode UTF-8 and fed into the PBKDF2 algorithm as a P parameter.

The integrity of PFX is ensured by using the HMAC_GOSTR3411_2012_512 algorithm in accordance with [RFC7836]. For checking the integrity of 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 of 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 macData.Salt and macData.iterations fileds 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 and should be completely absent.
