RSACryptoServiceProvider.UseMachineKeyStore Özellik

Tanım

Anahtarın kullanıcı profili deposu yerine bilgisayarın anahtar deposunda kalıcı olup olmayacağını belirten bir değer alır veya ayarlar.

public:
 static property bool UseMachineKeyStore { bool get(); void set(bool value); };
public static bool UseMachineKeyStore { get; set; }
static member UseMachineKeyStore : bool with get, set
Public Shared Property UseMachineKeyStore As Boolean

Özellik Değeri

true anahtarın bilgisayar anahtarı deposunda kalıcı olması gerekiyorsa; aksi takdirde , false.

Örnekler

Aşağıdaki kod örneği bir RSACryptoServiceProvider nesne oluşturur ve statik UseMachineKeyStore özelliğini kullanıcı profili anahtar deposu yerine makine anahtar depounu kullanacak şekilde ayarlar.

Açıklamalar

Bu özelliği olarak true ayarlamak, bayrağın bir CspParameters nesneye geçirilmesiyle UseMachineKeyStore eşdeğerdir. UseMachineKeyStore özelliği geçerli uygulama etki alanındaki tüm kodlara uygulanırkenCspParameters, nesne yalnızca açıkça başvuruda bulunan sınıflar için geçerlidir. Bu ayarlar, kullanıcı profili yüklenmeyen bir hesabın kimliğine bürünme veya bu hesabın altında çalışma sırasında kullanışlıdır. Ayar UseMachineKeyStore , anahtar deposu konumunu yalnızca RSACryptoServiceProvider parametre olmadan başlatıldığında etkiler.

Şunlara uygulanır
