GOST R 34.10-94 has been developed by "GUBS of Federal Agency
Government Communication and Information" and "All-Russian Scientific

contain the full GOST R 34.10-94 specification, which can be found in

[<a href="#ref-Schneier95" title="Second Edition">Schneier95</a>], ch. 20.3, p. 495, contains
a brief technical description in English.
The ASN.1 object identifier used to identify this signature algorithm
is:
id-GostR3411-94-with-GostR3410-94 OBJECT IDENTIFIER ::=
{ iso(1) member-body(2) ru(643) rans(2) cryptopro(2)
gostR3411-94-with-gostR3410-94(4) }
When the id-GostR3411-94-with-GostR3410-94 algorithm identifier
appears as the algorithm field in an AlgorithmIdentifier, the
encoding SHALL omit the parameters field. That is, the
AlgorithmIdentifier SHALL be a SEQUENCE of one component: the OBJECT
IDENTIFIER id-GostR3411-94-with-GostR3410-94.
The signature algorithm GOST R 34.10-94 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'.
This definition of a signature value is directly usable in CMS [<a href="#ref-CMS" title=""Cryptographic Message Syntax (CMS)"">CMS</a>],
where such values are represented as octet strings. However,
signature values in certificates and CRLs [<a href="#ref-PROFILE" title=""Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile"">PROFILE</a>] are represented
as bit strings, and thus the octet string representation must be
converted.

become the last bit of the bit string.
