override this.TryHashFinal : Span<byte> * int -> bool

Protected Overrides Function TryHashFinal (destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean

Parameters

destination: Span<Byte>

The buffer to receive the HMAC value.

bytesWritten: Int32

When this method returns, the total number of bytes written into destination. This parameter is treated as uninitialized.

Returns

Boolean

true if destination is long enough to receive the HMAC value; otherwise, false.
