Comentarios

De forma predeterminada, esta sobrecarga usa la HMACSHA1 implementación de un algoritmo hash con clave. Si desea especificar una implementación diferente, use la Create(String) sobrecarga , que le permite especificar un nombre de algoritmo, en su lugar. El sistema de configuración de criptografía define la implementación predeterminada de la KeyedHashAlgorithm clase .

Debido a problemas de colisión con SHA-1, Microsoft recomienda un modelo de seguridad basado en SHA-256 o superior.
