HashAlgorithm.HashCore Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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

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

Syntax

'Declaration
Protected MustOverride Sub HashCore ( _
    array As Byte(), _
    ibStart As Integer, _
    cbSize As Integer _
)

protected abstract void HashCore(
    byte[] array,
    int ibStart,
    int cbSize
)

Parameters

  • array
    Type: array<System.Byte[]
    The input to compute the hash code for.
  • ibStart
    Type: System.Int32
    The offset into the byte array from which to begin using data.
  • cbSize
    Type: System.Int32
    The number of bytes in the byte array to use as data.

Remarks

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 a correct hash value is returned at the end of the data stream.
