Decrypts the encrypted input data using the supplied key.

function decryptAsync(key, data, iv)

Public Shared Function DecryptAsync (key As CryptographicKey, data As IBuffer, iv As IBuffer) As IAsyncOperation(Of IBuffer)

Parameters

key: CryptographicKey

The key to use to decrypt the encrypted input data.

data: IBuffer

The encrypted data to decrypt.

iv: IBuffer

The initial vector for a symmetric key. For an asymmetric key, set this value to null.

Returns

IAsyncOperation<IBuffer>

The decrypted data.

Attributes: RemoteAsyncAttribute

Remarks

If the key is a persisted key and the decrypt operation requires UI or takes a long time, use the DecryptAsync method instead of the Decrypt method. For example, UI is required when decrypting using a key that is strongly protected.
