(C#) Hash the Contents of a String (SHA256 and other hash algorithms)

Demonstrates how to hash the contents of a string using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc.

// This example requires the Chilkat Crypt API to have been previously unlocked.
// See Unlock Chilkat Crypt for sample code.

Chilkat.Crypt2 crypt = new Chilkat.Crypt2();

// Choose the hash algorithm.
// Can be  "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".
crypt.HashAlgorithm = "sha256";

// The byte representation of the string matters when hashing. 
// Tell Chilkat that we want to use the utf-8 byte representation.
crypt.Charset = "utf-8";

byte[] hashBytes = null;
hashBytes = crypt.HashString("They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.");

// Let's examine the hash as a hex string.
Chilkat.StringBuilder sb = new Chilkat.StringBuilder();
sb.AppendEncoded(hashBytes,"hex");
Debug.WriteLine("SHA256 hash = " + sb.GetAsString());
