The AzureKeys component makes it easy to interact with keys in Azure Key Vaults.




The AzureKeys component provides an easy-to-use interface for the key-related functionality of the Azure Key Vault service. Azure Key Vault allows you to works with a few different kinds of resources, one of which is asymmetric key pairs. This component helps you to create, manage, and use said key pairs (or just "keys", for short) for cryptographic operations. To work with "secrets" instead, refer to the AzureSecrets component.

To begin, register for an Azure account and create one or more Key Vaults via the Azure Portal. Set the Vault property to the name of the vault you wish to work with.

This component supports authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth component or a separate process. Once complete you should have an authorization string which looks like:

Bearer ya29.AHES6ZSZEJzATdZYjeihDn5W-VrXSsxEZu5p0pclxGdKKQ
Assign this value to the Authorization property before attempting any operations. Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

Using the Component

Keys can be created using the CreateKey method. A key's name and type (i.e., whether it is RSA or EC, and its size or curve, respectively) must be set at the time of creation, and cannot be changed later. A list of cryptographic operations that the key is valid for must also be set, but can be changed at any time using the UpdateKey. If a key with the specified name already exists, a new version of it is created; this makes it easy to "rotate" a key.

When a key will no longer be used, it can be deleted using the DeleteKey method. However, the key will only be soft-deleted; by default, Azure will permanently delete it after the waiting period configured for the vault. During this waiting period, the soft-deleted key may be recovered using RecoverKey, or permanently deleted using PurgeKey (assuming the currently-authenticated user has the permissions to do so).

azurekeys.CreateKey("mykey", "RSA_2048", "encrypt,decrypt,sign,verify,wrapKey,unwrapKey");

// ... Some time later, when the key is no longer needed ...

// At this point, the key is only soft-deleted. It could be recovered...
// ...or permanently deleted.

To list keys, use the ListKeys method. This method is also used to list soft-deleted keys if the GetDeleted configuration setting has been enabled first. To list a key's versions, use the ListVersions method. (You cannot list a deleted key's versions.) In all cases, the IncludeKeyDetails property can optionally be enabled to have the component attempt to retrieve the full information for each key (Azure leaves out certain fields by default when listing).

// If there are many keys to list, there may be multiple pages of results. This will
// cause all pages of results to be accumulated into the Keys collection property.
do {
} while (!string.IsNullOrEmpty(azurekeys.KeyMarker));

// A similar thing applies to key versions as well.
do {
} while (!string.IsNullOrEmpty(azurekeys.VersionMarker));

Depending on a key's "key ops" list, it can be used to perform different cryptographic operations. Keys with the encrypt and decrypt ops can be used in Encrypt and Decrypt operations. Keys with the sign and verify ops can be used in Sign and Verify. Finally, keys with the wrapKey and unwrapKey ops can be used in WrapKey and UnwrapKey operations (which are just like encryption and decryption, but which are intended to be used for wrapping a symmetric key, and which require different permissions to call successfully).

To perform a cryptographic operation, use InputData, InputFile, or SetInputStream to supply the input data that should be processed. All operations will output the result data to OutputData, OutputFile, or SetOutputStream (except Verify; refer to its documentation for more information).

azurekeys.CreateKey("mykey", "RSA_2048", "encrypt,decrypt");

azurekeys.InputData = "Test123";
azurekeys.OutputFile = "C:/temp/enc.dat";
azurekeys.Encrypt("mykey", "RSA-OAEP-256");

azurekeys.InputFile = "C:/temp/enc.dat";
azurekeys.OutputFile = ""; // So that the data will be output to the OutputData property.
azurekeys.Decrypt("mykey", "RSA-OAEP-256");

The component also supports a variety of other functionality, including:
