Answer:

Explanation:

byte[] HashValue;

string MessageString = "This is the original message!";

//Create a new instance of the UnicodeEncoding class to

//convert the string into an array of Unicode bytes.

UnicodeEncoding UE = new UnicodeEncoding();

//Convert the string into an array of bytes.

byte[] MessageBytes = UE.GetBytes(MessageString);

//Create a new instance of the SHA1Managed class to create

//the hash value.

SHA1Managed SHhash = new SHA1Managed();

//Create the hash value from the array of bytes.

HashValue = SHhash.ComputeHash(MessageBytes);
