Public Event EncryptedFileIntegrityCheckFailed As EncryptedFileIntegrityCheckFailedEventHandler
The EncryptedFileIntegrityCheckFailed event's data class is EncryptedFileIntegrityCheckFailedEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs. |
RichEditControl uses the Hash-based message authentication code (HMAC) to verify the document data integrity. If the document did not pass the code verification, the EncryptedFileIntegrityCheckFailed event is raised.
Note
The HMAC is calculated only for certain encryption types. When you save a password encrypted document, set the Type to the EncryptionType.Strong to calculate HMAC.
