Caution

Code Access Security is not supported or honored by the runtime.

Specifies the type of key container access allowed.

This enumeration supports a bitwise combination of its member values.

Fields

Name Value Description
NoFlags 0

No access to a key container.
Create 1

Create a key container.

Creating a key container also creates a file on disk. It is very important that any key container that is created is removed when it is no longer in use.
Open 2

Open a key container and use the public key.

Open does not give permission to sign or decrypt files using the private key, but it does allow a user to verify file signatures and to encrypt files. Only the owner of the key is able to decrypt these files using the private key.
Delete 4

Delete a key container.

Deleting a key container can constitute a denial of service attack because it prevents the use of files encrypted or signed with the key. Therefore, deletion is a privileged operation.
Import 16

Import a key into a key container.

The ability to import a key can be as harmful as the ability to delete a container because importing a key into a named key container replaces the existing key.
Export 32

Export a key from a key container.

The ability to export a key is potentially harmful because it removes the exclusivity of the key.
Sign 256

Sign a file using a key.

The ability to sign a file is potentially harmful because it can allow a user to sign a file using another user's key.
Decrypt 512

Decrypt a key container.

Decryption is a privileged operation because it uses the private key.

ViewAcl 4096

View the access control list (ACL) for a key container.
ChangeAcl 8192

Change the access control list (ACL) for a key container.
AllFlags 13111

Create, decrypt, delete, and open a key container; export and import a key; sign files using a key; and view and change the access control list for a key container.

Examples

The following example shows the use of the KeyContainerPermissionFlags enumeration.

// Create a KeyContainerPermission with the right to open the key container.
KeyContainerPermission ^ keyContainerPerm = gcnew KeyContainerPermission( KeyContainerPermissionFlags::Open );

// Create a KeyContainerPermission with the right 
// to open the key container.
KeyContainerPermission keyContainerPerm = new
     KeyContainerPermission(KeyContainerPermissionFlags.Open);

' Create a KeyContainerPermission with the right to open the key container.
Dim keyContainerPerm As New KeyContainerPermission(KeyContainerPermissionFlags.Open)

Remarks

Caution

Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.

This enumeration is used by members of the KeyContainerPermissionAccessEntry class.

Caution

Many of these flags can have powerful effects and should be granted only to highly trusted code.

The most powerful flags are Create, Delete, Import, Export, Sign, Decrypt, and AllFlags. For specific threats that the use of these flags can present, see the member descriptions.
