IKeyVaultClient.UnwrapKeyWithHttpMessagesAsync Method

Definition

Unwraps a symmetric key using the specified key that was initially used for wrapping that key.

public System.Threading.Tasks.Task<Microsoft.Rest.Azure.AzureOperationResponse<Microsoft.Azure.KeyVault.Models.KeyOperationResult>> UnwrapKeyWithHttpMessagesAsync (string vaultBaseUrl, string keyName, string keyVersion, string algorithm, byte[] value, System.Collections.Generic.Dictionary<string,System.Collections.Generic.List<string>> customHeaders = default, System.Threading.CancellationToken cancellationToken = default);
abstract member UnwrapKeyWithHttpMessagesAsync : string * string * string * string * byte[] * System.Collections.Generic.Dictionary<string, System.Collections.Generic.List<string>> * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Microsoft.Rest.Azure.AzureOperationResponse<Microsoft.Azure.KeyVault.Models.KeyOperationResult>>
Public Function UnwrapKeyWithHttpMessagesAsync (vaultBaseUrl As String, keyName As String, keyVersion As String, algorithm As String, value As Byte(), Optional customHeaders As Dictionary(Of String, List(Of String)) = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Task(Of AzureOperationResponse(Of KeyOperationResult))

Parameters

vaultBaseUrl
String

The vault name, for example https://myvault.vault.azure.net.

keyName
String

The name of the key.

keyVersion
String

The version of the key.

algorithm
String

algorithm identifier. Possible values include: 'RSA-OAEP', 'RSA-OAEP-256', 'RSA1_5'

value
Byte[]
customHeaders
Dictionary<String,List<String>>

The headers that will be added to request.

cancellationToken
CancellationToken

The cancellation token.

Returns

Remarks

The UNWRAP operation supports decryption of a symmetric key using the target key encryption key. This operation is the reverse of the WRAP operation. The UNWRAP operation applies to asymmetric and symmetric keys stored in Azure Key Vault since it uses the private portion of the key. This operation requires the keys/unwrapKey permission.
