Inheritance: Object GMac

Implements: IMac

Remarks

GMac is an invocation of the GCM mode where no data is encrypted (i.e. all input data to the Mac is processed as additional authenticated data with the underlying GCM block cipher).

Constructors

GMac(GcmBlockCipher)	Creates a GMAC based on the operation of a block cipher in GCM mode.
GMac(GcmBlockCipher, Int32)	Creates a GMAC based on the operation of a 128 bit block cipher in GCM mode.

Methods

BlockUpdate(ReadOnlySpanByte)
BlockUpdate(Byte, Int32, Int32)
DoFinal(SpanByte)
DoFinal(Byte, Int32)
Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetMacSize
GetType	Gets the Type of the current instance. (Inherited from Object)
Init	Initialises the GMAC - requires a ParametersWithIV providing a KeyParameter and a nonce.
MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
Reset
ToString	Returns a string that represents the current object. (Inherited from Object)
