(VB.NET UWP/WinRT) 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.

Dim crypt As 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"

Dim hashBytes() As Byte
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.
Dim sb As New Chilkat.StringBuilder
sb.AppendEncoded(hashBytes,"hex")
Debug.WriteLine("SHA256 hash = " & sb.GetAsString())
