(Xojo Plugin) Hash the Contents of a File (SHA256 and other hash algorithms)
Demonstrates how to hash the contents of a file using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc.
// 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"
Dim hashBytes As MemoryBlock
hashBytes = crypt.HashFile("qa_data/jpg/starfish.jpg")
// 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())
