Excepciones

PlatformNotSupportedException

.NET Core 2.0 - 3.1 y .NET 5 y versiones posteriores: en todos los casos.

Comentarios

Este método está obsoleto en .NET 5 y versiones posteriores.

De forma predeterminada, esta sobrecarga usa la SHA1CryptoServiceProvider implementación de un algoritmo hash. 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 HashAlgorithm.

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