Detalles Técnicos

The error code 0x80090006 is an HRESULT, a standard Microsoft format for encoding errors in system components. The structure of an HRESULT is composed of several fields: el bit de severidad (the highest bit), the client code (que indica si es un error o un éxito), el código de instalación (facility code) and the specific error code. En el caso de 0x80090006, se descompone de la siguiente manera:

• Severidad: El valor 0x8 (en binario, el bit SEVERITY_ERROR) indica que se trata de un error grave, lo que significa que la operación falló y no se puede continuar sin intervención.
• Código de Cliente: Este bit (0x0 en este caso) especifica que es un error del sistema, no de un cliente personalizado.
• Installation Code (Facility Code): El valor 0x9 corresponde a FACILITY_SSPI (Security Support Provider Interface), que abarca errores relacionados con la autenticación y la criptografía, particularmente en el contexto de CryptoAPI y CNG.
• Specific Error Code: El valor 0x0006 se traduce a NTE_BAD_SIGNATURE, que denota una firma inválida o corrupta.

Técnicamente, este error se genera en APIs como CryptAcquireContext, CryptImportKey O NCryptOpenStorageProvider en CNG, que son funciones utilizadas para manejar proveedores de servicios criptográficos (CSPs) o proveedores de aislamiento (CNG providers). For example, when trying to import a private key with a signature that does not match, the system returns 0x80090006. In Windows 10 Y 11, this error can involve processes like lsass.exe (Local Security Authority) or the CryptSvc service, which depend on libraries like crypt32.dll and ncrypt.dll.

Las dependencias incluyen el Registro de Windows, where CSP configurations are stored in paths like HKEY_LOCAL_MACHINESOFTWAREMicrosoftCryptography, and hardware components like TPM, which can fail if there are firmware problems. Para desarrolladores, this error is handled through checks in code, utilizando funciones como GetLastError() en C++ o excepciones en .NET. An example of a structure in code could be:

HRESULT hr = CryptAcquireContext(&hProv, NULL, MS_ENH_RSA_AES_PROV, PROV_RSA_AES, 0);
if (FAILED(hr) && hr == NTE_BAD_SIGNATURE) {
 // Manejar el error: firma inválida
 printf("Error: 0xX - Firma inválidan", hr);
}

In Windows 11, with improvements in CNG, the error can arise in asynchronous operations, requiring the use of events or callbacks for its handling. This adds complexity, ya que los procesos deben verificar la integridad de las claves antes de proceder, impactando en el rendimiento de aplicaciones que utilizan criptografía, como navegadores o VPNs.
