You are developing a method to hash data with the Secure Hash Algorithm. The data is passed to your method as a byte array named message. You need to compute the hash of the incoming parameter by using SHA1. You also need to place the result into a byte array named hash. Which code segment should you use?

You are developing a method to hash data with the Secure Hash Algorithm. The data is passed
to your method as a byte array named message. You need to compute the hash of the incoming
parameter by using SHA1. You also need to place the result into a byte array named hash. Which
code segment should you use?

A. Dim objSHA As New SHA1CryptoServiceProviderDim hash() As Byte =
    NothingobjSHA.TransformBlock(message, 0, message.Length, hash, 0)
B. Dim objSHA As New SHA1CryptoServiceProviderDim hash() As Byte =
    BitConverter.GetBytes(objSHA.GetHashCode)
C. Dim objSHA As New SHA1CryptoServiceProviderDim hash() As Byte =
    objSHA.ComputeHash(message)
D. Dim objSHA As New SHA1CryptoServiceProviderobjSHA.GetHashCode()Dim
    hash() As Byte = objSHA.Hash

Answer: C
