1. Introduction

This document describes the conventions for using the GOST R 34.10-2012 signature algorithm [GOSTR3410-2012] [RFC7091] and the GOST R 34.11-2012 hash function [GOSTR3411-2012] [RFC6986] 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 Certificate Revocation Lists (CRLs). For each algorithm, the appropriate alternatives for the keyUsage certificate extension are provided.

This specification is developed to facilitate implementations that wish to support the GOST algorithms. This document does not imply IETF endorsement of the cryptographic algorithms used in this document.

1.1. 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] when, and only when, they appear in all capitals, as shown here.

2. Signature Algorithm Support

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

The ASN.1 object identifier (OID) used to identify the GOST R 34.10-2012 signature algorithm with a 256-bit key length and the GOST R 34.11-2012 hash function with a 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)}

The GOST R 34.10-2012 signature algorithm with a 256-bit key length generates a digital signature in the form of two 256-bit integers: 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 OID used to identify the GOST R 34.10-2012 signature algorithm with a 512-bit key length and the GOST R 34.11-2012 hash function with a 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)}

The GOST R 34.10-2012 signature algorithm with a 512-bit key length generates a digital signature in the form of two 512-bit integers: 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 OIDs 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 the Cryptographic Message Syntax (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 Function Support

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

   id-tc26-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 OID used to identify the GOST R 34.11-2012 hash function with a 512-bit hash code is:

   id-tc26-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 OIDs 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 a 256-bit 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 a 512-bit 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 the algorithm field in the SubjectPublicKeyInfo.algorithm.algorithm field, the parameters field MUST have the following structure:

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

where:

• publicKeyParamSet is the public key parameters identifier for GOST R 34.10-2012 parameters (see Sections 5.1.1 and 5.2.1 of [RFC7836] or Appendix C) or GOST R 34.10-2001 parameters (see Section 8.4 of [RFC4357]).

• digestParamSet is the parameters identifier for the corresponding GOST R 34.11-2012 parameters (see Section 3).

The following values, when used as publicKeyParamSet, define test public key parameter sets and MUST NOT be used outside of testing scenarios:

   *  id-GostR3410-2001-TestParamSet
   
   *  id-tc26-gost-3410-2012-512-paramSetTest

The digestParamSet field:

• SHOULD be omitted if the GOST R 34.10-2012 signature algorithm is used with a 512-bit key length

• MUST be present and must be equal to id-tc26-digest- gost3411-12-256 if one of the following values is used as publicKeyParamSet:

      -  id-GostR3410-2001-TestParamSet
      
      -  id-GostR3410-2001-CryptoPro-A-ParamSet
      
      -  id-GostR3410-2001-CryptoPro-B-ParamSet
      
      -  id-GostR3410-2001-CryptoPro-C-ParamSet
      
      -  id-GostR3410-2001-CryptoPro-XchA-ParamSet
      
      -  id-GostR3410-2001-CryptoPro-XchB-ParamSet

• SHOULD be omitted if publicKeyParamSet is equal to:

      -  id-tc26-gost-3410-2012-256-paramSetA

• MUST be omitted if one of the following values is used as publicKeyParamSet:

      -  id-tc26-gost-3410-2012-256-paramSetB
      
      -  id-tc26-gost-3410-2012-256-paramSetC
      
      -  id-tc26-gost-3410-2012-256-paramSetD

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 the SubjectPublicKeyInfo structure.

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

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

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

4.4. Key Usage Extension

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

• digitalSignature (0)

• contentCommitment (1)

• keyEncipherment (2)

• dataEncipherment (3)

• keyAgreement (4)

• keyCertSign (5)

• cRLSign (6)

• encipherOnly (7)

• decipherOnly (8)

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

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

5. Qualified Certificate Extensions

This section defines additional 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 (SIZE(13))

The corresponding OID is 1.2.643.100.1.

SNILS is the individual insurance account number.

   SNILS ::= NUMERIC STRING (SIZE(11))

The corresponding OID is 1.2.643.100.3.

INNLE is the individual taxpayer number (ITN) of the legal entity.

   INNLE ::= NUMERIC STRING (SIZE(10))

The corresponding OID is 1.2.643.100.4.

OGRNIP is the main state registration number of individual entrepreneurs (sole traders).

   OGRNIP ::= NUMERIC STRING (SIZE(15))

The corresponding OID is 1.2.643.100.5.

IdentificationKind represents the way the receiver of the certificate was identified by the CA.

   IdentificationKind ::= INTEGER { personal(0), remote-cert(1),
               remote-passport(2), remote-system(3) }

The corresponding OID is 1.2.643.100.114.

INN is the individual taxpayer number (ITN).

   INN ::= NUMERIC STRING (SIZE(12))

The corresponding OID is 1.2.643.3.131.1.1.

5.2. Certificate Policies

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

   *  1.2.643.100.113.1 - class KC1
   
   *  1.2.643.100.113.2 - class KC2
   
   *  1.2.643.100.113.3 - class KC3
   
   *  1.2.643.100.113.4 - class KB1
   
   *  1.2.643.100.113.5 - class KB2
   
   *  1.2.643.100.113.6 - class KA1

5.3. Subject Sign Tool

To denote the token or software type used by the certificate owner, the 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 pairs and tools used by the CA to sign certificates, the 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:

• signTool identifies tools used to create key pairs.

• cATool identifies tools used by the CA.

• signToolCert and cAToolCert contain the notice of the conformance of respective tools to Russian federal law on digital signatures.

6. Historical Considerations

Note that, for a 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 the digestParamSet field is not included in 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:

   *  id-tc26-gost-3410-12-512-paramSetA
   
   *  id-tc26-gost-3410-12-512-paramSetB

Note that the usage of keyEncipherment and dataEncipherment values for the KeyUsage extension is not fully defined for the GOST R 34.10-2012 public keys, so they SHOULD be used with additional care.

7. IANA Considerations

This document has no IANA actions.

8. Security Considerations

It is RECOMMENDED that applications verify signature values and subject public keys to conform to the GOST R 34.10-2012 standard [GOSTR3410-2012] [RFC7091] 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 the GOST R 34.10-2012 algorithm).

Test parameter sets (id-GostR3410-2001-TestParamSet and id-tc26-gost- 3410-2012-512-paramSetTest) MUST NOT be used outside of testing scenarios. The use of parameter sets not described herein is NOT RECOMMENDED. When different parameters are used, it is RECOMMENDED that they be subjected to examination by an authorized agency with approved methods of cryptographic analysis.

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

Appendix C. Public Key Parameters

Here we define three new OIDs for three existing public key parameter sets defined in [RFC4357]. These OIDs 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)
           constants(2) sign-constants(1) gost-3410-12-256-constants(1)
             paramSetB(2)}
   
   The elliptic curve of this parameter set is the same as that of id-
   GostR3410-2001-CryptoPro-A-ParamSet (and id-GostR3410-2001-CryptoPro-
   XchA-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)
           constants(2) sign-constants(1) gost-3410-12-256-constants(1)
             paramSetC(3)}

The elliptic curve of this parameter set is the same as that 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)
           constants(2) sign-constants(1) gost-3410-12-256-constants(1)
             paramSetD(4)}
   
   The elliptic curve of this parameter set is the same as that of id-
   GostR3410-2001-CryptoPro-C-ParamSet (and id-GostR3410-2001-CryptoPro-
   XchB-ParamSet), which can be found in [RFC4357].

Appendix D. Test Examples
