Overloads
| DoFinal() |
Finishes the MAC operation. |
| DoFinal(Byte[]) |
Processes the given array of bytes and finishes the MAC operation. |
| DoFinal(Byte[], Int32) |
Finishes the MAC operation. |
DoFinal()
Finishes the MAC operation.
[Android.Runtime.Register("doFinal", "()[B", "")]
public byte[]? DoFinal ();[<Android.Runtime.Register("doFinal", "()[B", "")>]
member this.DoFinal : unit -> byte[]Returns
the MAC result.
- Attributes
Exceptions
if this MAC is not initialized.
Remarks
Finishes the MAC operation.
A call to this method resets this Mac object to the state it was in when previously initialized via a call to init(Key) or init(Key, AlgorithmParameterSpec). That is, the object is reset and available to generate another MAC from the same key, if desired, via new calls to update and doFinal. (In order to reuse this Mac object with a different key, it must be reinitialized via a call to init(Key) or init(Key, AlgorithmParameterSpec).

Applies to
DoFinal(Byte[], Int32)
Finishes the MAC operation.
[Android.Runtime.Register("doFinal", "([BI)V", "")]
public void DoFinal (byte[]? output, int outOffset);[<Android.Runtime.Register("doFinal", "([BI)V", "")>]
member this.DoFinal : byte[] * int -> unitParameters
- output
- Byte[]
the buffer where the MAC result is stored
- outOffset
- Int32
the offset in output where the MAC is
stored
- Attributes
Exceptions
if the specified output buffer is either too small for the
digest to be stored, the specified output buffer is null, or the specified offset is negative or past the length
of the output buffer.
if this MAC is not initialized.

Finishes the MAC operation.

(In order to reuse this Mac object with a different key, it must be reinitialized via a call to init(Key) or init(Key, AlgorithmParameterSpec).
The MAC result is stored in output, starting at outOffset inclusive.
