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

See more Encryption Examples

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

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample 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 MemoryBlock
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
Dim success As Boolean
success = sb.AppendEncoded(hashBytes,"hex")
System.DebugLog("SHA256 hash = " + sb.GetAsString())
