You are developing a method to hash data with the Secure Hash Algorithm.

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. SHA1 sha = new SHA1CryptoServiceProvider();byte[] hash =     
    null;sha.TransformBlock(message, 0, message.Length, hash, 0);
B. SHA1 sha = new SHA1CryptoServiceProvider();byte[] hash =     
    BitConverter.GetBytes(sha.GetHashCode());
C. SHA1 sha = new SHA1CryptoServiceProvider();byte[] hash = sha.ComputeHash(message);
D. SHA1 sha = new SHA1CryptoServiceProvider();sha.GetHashCode();byte[] hash = sha.Hash;

Answer: C
