Příklady

Následující příklad ukazuje implementaci ProviderUnprotect metody.The following example shows an implementation of the ProviderUnprotect method. Je součástí většího příkladu kódu pro DataProtector třídu.It is part of a larger code example for the DataProtector class.

// To allow a service to hand out instances of a DataProtector we demand unrestricted DataProtectionPermission 
// in the constructor, but Assert the permission when ProviderUnprotect is called..  This is similar to FileStream
// where access is checked at time of creation, not time of use.
[SecuritySafeCritical]
[DataProtectionPermission(SecurityAction.Assert, UnprotectData = true)]
protected override byte[] ProviderUnprotect(byte[] encryptedData)
{

    ProtectedMemory.Unprotect(encryptedData,Scope);           
        return encryptedData;
}
