Table of Contents

1. Introduction

This document supplements [RFC3279]. It describes the conventions for using the GOST R 34.10-2012 (see [RFC7091]) signature algorithm and GOST R 34.11-2012 (see [RFC6986]) hash function in the Internet X.509 Public Key Infrastructure (PKI) [RFC5280].

This specification defines the contents of the signatureAlgorithm, signatureValue, signature, and subjectPublicKeyInfo fields within X.509 Certificates and CRLs. For each algorithm, the appropriate alternatives for the keyUsage certificate extension are provided.

1.1. 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 [RFC2119].

2. Signature algorithm support

Conforming CAs MAY use GOST R 34.10-2012 signature algorithm to sign certificates and CRLs. This signature algorithm MUST always be used with GOST R 34.11-2012 hash function. It may use keys length of either 256 bits or 512 bits.

The ASN.1 object identifier used to identify GOST R 34.10-2012 signature algorithm with 256-bit key length and GOST R 34.11-2012 hash function with 256-bit hash code is:

id-tc26-signwithdigest-gost3410-12-256 OBJECT IDENTIFIER ::=
    { iso(1) member-body(2) ru(643) rosstandart(7) tc26(1)
        algorithms(1) signwithdigest(3) gost3410-12-256(2)}.

GOST R 34.10-2012 signature algorithm with 256-bit key length generates a digital signature in the form of two 256-bit numbers, r and s. Its octet string representation consists of 64 octets, where the first 32 octets contain the big-endian representation of s and the second 32 octets contain the big-endian representation of r.

The ASN.1 object identifier used to identify GOST R 34.10-2012 signature algorithm with 512-bit key length and GOST R 34.11-2012 hash function with 512-bit hash code is:

id-tc26-signwithdigest-gost3410-12-512 OBJECT IDENTIFIER ::=
    { iso(1) member-body(2) ru(643) rosstandart(7) tc26(1)
        algorithms(1) signwithdigest(3) gost3410-12-512(3)}.

GOST R 34.10-2012 signature algorithm with 512-bit key length generates a digital signature in the form of two 512-bit numbers, r and s. Its octet string representation consists of 128 octets, where the first 64 octets contain the big-endian representation of s and the second 64 octets contain the big-endian representation of r.

When either of these OID is used as the algorithm field in an AlgorithmIdentifier structure, the encoding MUST omit the parameters field.

The described definition of a signature value is directly usable in CMS [RFC5652], where such values are represented as octet strings. However, signature values in certificates and CRLs [RFC5280] are represented as bit strings, and thus the octet string representation must be converted.

To convert an octet string signature value to a bit string, the most significant bit of the first octet of the signature value SHALL become the first bit of the bit string, and so on through the least significant bit of the last octet of the signature value, which SHALL become the last bit of the bit string.

3. Hash functions support

The ASN.1 object identifier used to identify GOST R 34.11-2012 hash function with 256-bit hash code is:

id-tc26-digest-gost3411-12-256 OBJECT IDENTIFIER ::=
    { iso(1) member-body(2) ru(643) rosstandart(7) tc26(1)
        algorithms(1) digest(2) gost3411-12-256(2)}.

The ASN.1 object identifier used to identify GOST R 34.11-2012 hash function with 512-bit hash code is:

id-tc26-digest-gost3411-12-512 OBJECT IDENTIFIER ::=
    { iso(1) member-body(2) ru(643) rosstandart(7) tc26(1)
        algorithms(1) digest(2) gost3411-12-512(3)}.

When either of these OID is used as the algorithm field in an AlgorithmIdentifier structure, the encoding MUST omit the parameters field.

4. Subject Public Keys Information Fields

4.1. Public Key identifiers

GOST R 34.10-2012 public keys with 256 bits private key length are identified by the following OID:

id-tc26-gost3410-12-256 OBJECT IDENTIFIER ::=
    { iso(1) member-body(2) ru(643) rosstandart(7) tc26(1)
        algorithms(1) sign(1) gost3410-12-256(1)}.

GOST R 34.10-2012 public keys with 512 bits private key length are identified by the following OID:

id-tc26-gost3410-12-512 OBJECT IDENTIFIER ::=
    { iso(1) member-body(2) ru(643) rosstandart(7) tc26(1)
        algorithms(1) sign(1) gost3410-12-512(2)}.

4.2. Public Key parameters

When either of these identifiers appears as algorithm field in SubjectPublicKeyInfo.algorithm.algorithm field, parameters field MUST have the following structure:

GostR3410-2012-PublicKeyParameters ::= SEQUENCE
    {
        publicKeyParamSet OBJECT IDENTIFIER,
        digestParamSet OBJECT IDENTIFIER OPTIONAL
    }

where:

The field digestParamSet:

4.3. Public Key encoding

The GOST R 34.10-2012 public key MUST be ASN.1 DER encoded as an OCTET STRING. This encoding SHALL be used as the content (i.e., the value) of the subjectPublicKey field (a BIT STRING) of SubjectPublicKeyInfo structure.

GostR3410-2012-256-PublicKey ::= OCTET STRING (64),
GostR3410-2012-512-PublicKey ::= OCTET STRING (128).

GostR3410-2012-256-PublicKey MUST contain 64 octets, where the first 32 octets contain the little-endian representation of x and the second 32 octets contains the little-endian representation of y coordinates of the public key.

GostR3410-2012-512-PublicKey MUST contain 128 octets, where the first 64 octets contain the little-endian representation of x and the second 64 octets contains the little-endian representation of y coordinates of the public key.

4.4. Key usage extension

If the KeyUsage extension is present in a certificate with GOST R 34.10-2012 public key, the following values MAY be present:

Note that contentCommitment was named nonRepudiation in previous versions of X.509.

If the key is going to be used for key agreement, flag keyAgreement MUST be present in KeyUsage extension with encipherOnly and decipherOnly flags being optional. However flags encipherOnly and decipherOnly flags MUST NOT be present simultaneously.

5. Qualified certificates extensions

This section defines additional object identifiers (OIDs) for use in qualified certificates for checking digital signatures.

5.1. Distinguished Name additions

OGRN is the main state registration number of juridical entities.

OGRN ::= NUMERIC STRING 13

Corresponding OID is 1.2.643.100.1.

SNILS is the individual insurance account number.

SNILS ::= NUMERIC STRING 11

Corresponding OID is 1.2.643.100.3.

OGRNIP is the main state registration number of individual enterpreneurs.

OGRNIP ::= NUMERIC STRING 15

Corresponding OID is 1.2.643.100.5.

INN is the individual taxpayer number (ITN).

INN ::= NUMERIC STRING 12

Corresponding OID is 1.2.643.3.131.1.1.

5.2. Certificate policies

Russian national regulation body for cryptography defines several security levels of cryptographic tools. Depending on the class of cryptographic token used by certificate owner the following OIDs must be included into certificate policies. Certificate should include OIDs starting from the lowest one (KC1) up to the strongest applicable.

5.3. Subject Sign Tool

To denote the token or software type used by certificate owner following non-critical SubjectSignTool extension with OID 1.2.643.100.111 should be included. It is defined as

SubjectSignTool ::= UTF8String SIZE(1..200) .

5.4. Issuer Sign Tool

To denote the tools used to generate key pair and tools used by CA to sign certificate following non-critical IssuerSignTool extension with OID 1.2.643.100.112 should be included. It is defined as

IssuerSignTool ::= SEQUENCE {
  signTool     UTF8String SIZE(1..200),
  cATool       UTF8String SIZE(1..200),
  signToolCert UTF8String SIZE(1..100),
  cAToolCert   UTF8String SIZE(1..100) }, 

where:

6. Historical Considerations

Note that for the significant period of time there were no documents describing GostR3410-2012-PublicKeyParameters. Several old implementations have used GostR3410-2001-PublicKeyParameters instead. These implementations will return an error if digestParamSet field is not included into public key parameters. Thus an implementation wishing to collaborate with old implementations might want to include digestParamSet equal to id-tc26-digest-gost3411-12-512 if one of the following values is used as publicKeyParamSet:

7. IANA Considerations

This memo includes no request to IANA.

8. Security Considerations

It is RECOMMENDED that applications verify signature values and subject public keys to conform to [RFC7091] standard prior to their use.

It is RECOMMENDED that CAs and applications make sure that the private key for creating signatures is not used for more than its allowed validity period (typically 15 months for GOST R 34.10-2012 algorithm).

For security discussion concerning use of algorithm parameters, see [ANS17] and the Security Considerations sections in [RFC4357], [RFC7836].

Appendix B. Public key parameters

Here we define three new object identifiers for three existing public key parameter sets defined in [RFC4357]. These object identifiers MUST be used with GOST R 34.10-2012 public keys only.

id-tc26-gost-3410-2012-256-paramSetB OBJECT IDENTIFIER ::=
    { iso(1) member-body(2) ru(643) rosstandart(7) tc26(1)

        gost-3410-12-256-constants(1) paramSetB(2)}.

The elliptic curve of this parameter set is the same as of id-GostR3410-2001-CryptoPro-A-ParamSet which can be found in [RFC4357].

id-tc26-gost-3410-2012-256-paramSetC OBJECT IDENTIFIER ::=
    { iso(1) member-body(2) ru(643) rosstandart(7) tc26(1)
        ru(643) rosstandart(7) tc26(1) constants(2) sign-constants(1)
        gost-3410-12-256-constants(1) paramSetC(3)}.

The elliptic curve of this parameter set is the same as of id-GostR3410-2001-CryptoPro-B-ParamSet which can be found in [RFC4357].

id-tc26-gost-3410-2012-256-paramSetD OBJECT IDENTIFIER ::=
    { iso(1) member-body(2) ru(643) rosstandart(7) tc26(1)
        ru(643) rosstandart(7) tc26(1) constants(2) sign-constants(1)
        gost-3410-12-256-constants(1) paramSetD(4)}.

The elliptic curve of this parameter set is the same as of id-GostR3410-2001-CryptoPro-C-ParamSet which can be found in [RFC4357].
