HMAC::HashCore Method

When overridden in a derived class, routes data written to the object into the default HMAC hash algorithm for computing the hash value.

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

protected:
virtual void HashCore(
	array<unsigned char>^ rgb, 
	int ib, 
	int cb
) override

Parameters

rgb
Type: array<System::Byte>

The input data.

ib
Type: System::Int32

The offset into the byte array from which to begin using data.

cb
Type: System::Int32

The number of bytes in the array to use as data.

This method is not called by application code.

This abstract method performs the hash computation. Every write to the cryptographic stream object passes the data through this method. For each block of data, this method updates the state of the hash object so that a correct hash value is returned at the end of the data stream.
