How to locate new certification using Certutil? - command-line

Question

I need to create a new cert and then locate it to obtain the serial number (to use it later to get the public and private keys).
If I make a new certificate with makecert utility from Microsoft SDK's like this:
makecert -r -pe -a sha1 -n "CN=ElektroSoft" -b 01/01/2013 -e 01/01/2050 -ss my -$ individual
Then I suppose that cert will be stored in "my"...
..But when I try to list the "my" certificates I only get one entry, and is not my new certificate:
C:\>CERTUTIL -store my
my
================ Certificado 0 ================
Número de serie: 586a7358ebdce8854def26875f0f38ab
Emisor: CN=localhost
NotBefore: 22/02/2013 4:43
NotAfter: 22/02/2018 2:00
Sujeto: CN=localhost
La firma coincide con la clave pública
Certificado raíz: el sujeto coincide con el emisor
Plantilla:
Hash de cert(sha1): 1b 92 19 ef 19 ce d1 09 ad 87 13 73 56 0c cf 0a 57 29 cf 81
Contenedor de claves = IIS Express Development Certificate Container
Nombre de contenedor exclusivo: fad662b360941f26a1193357aab3c12d_a61f2a11-eaf9
-4c14-9a63-d3613bf3bd2c
Proveedor = Microsoft RSA SChannel Cryptographic Provider
Prueba de cifrado correcta
CertUtil: -store comando completado correctamente.
Then where is stored my new certificate?

Answer 1

Finally I did my code:
#Echo OFF
Setlocal enabledelayedexpansion
Set "Name=ElektroSoft"
Set "Password=Elektro"
Set "InitialDate=01/01/2013"
Set "ExpireDate=01/01/2050"
Set "SerialNumber=%Random%%Random%%Random%%Random%%Random%"
:: Make certificate
makecert -r -pe -a sha1 -n "CN=%Name%" -b "%InitialDate%" -e "%ExpireDate%" -$ individual -sr LocalMachine -ss my -cy authority -# "%SerialNumber%" "%Name%.cer"
:: Export certificate
For /F "Tokens=2 delims=:" %%# in ('certutil -store my') DO (
if "%%#" NEQ " CN=%Name%" (Set "SerialNumberHash=%%#") ELSE (
certutil -exportPFX -p "%Password%" my "!SerialNumberHash: =!" "%Name%.pfx"
Pause&Exit))
:: Check certificate
REM certutil -store my
:: Delete certificate
REM certutil -delstore MY "%Name%"
