CSD 2048 y libreria Sgenc32

[Manuel Garcia]

Que tal Buenos dias!!
Tengo un detalle con las nuevas Fiel RSA 2048 bits.
Actualmente para generar la firma digital utilizo un programa en Visual Basic y especificamente uso la siguiente función:

Código: Seleccionar todo

Declare Function BuscaCurps Lib "sgenc32" Alias "_BuscaCurps@8" (ByVal strArchOrig As String, ByRef CURPS() As registro_CURP) As Long
Declare Function GeneraFirmaDigital Lib "sgenc32" Alias "_GeneraFirmaDigital@8" (ByVal strArchOrig As String, ByRef CURPS() As registro_CURP) As Long

La duda es que función debo utilizar para generar la firma de 2048 bits? tengo otras funciones declaras sin embargo no las uso:

Código: Seleccionar todo

Declare Function BuscaCurps_std Lib "sgenc32" Alias "_BuscaCurps_std@8" (ByVal strArchOrig As String, ByRef CURPS() As registro_CURP) As Long
Declare Function GeneraFirmaDigital_std Lib "sgenc32" Alias "_GeneraFirmaDigital_std@12" (ByVal strArchOrig As String, ByRef CURPS() As registro_CURP) As Long

Declare Function BuscaCurpsG Lib "sgenc32" Alias "_BuscaCurpsG@12" (ByVal strArchOrig As String, ByVal tipo As Long, ByRef CURPSG() As registro_CURPG) As Long
Declare Function GeneraFirmaDigitalG Lib "sgenc32" Alias "_GeneraFirmaDigitalG@12" (ByVal strArchOrig As String, ByVal tipo As Long, ByRef CURPSG() As registro_CURPG) As Long

Declare Function BuscaCurpsG_std Lib "sgenc32" Alias "_BuscaCurpsG_std@12" (ByVal strArchOrig As String, ByVal tipo As Long, ByRef CURPSG() As registro_CURPG) As Long
Declare Function GeneraFirmaDigitalG_std Lib "sgenc32" Alias "_GeneraFirmaDigitalG_std@12" (ByVal strArchOrig As String, ByVal tipo As Long, ByRef CURPSG() As registro_CURPG) As Long

Alguien podria orientarme?.
gracias.
saludos.
