(Xojo Plugin) SHA256 Hash the Bytes Represented in a Hex String

Demonstrates how to compute the SHA256 hash of the bytes represented by a hexidecimal encoded string, and return the hash bytes as an hex encoded string.

// This example assumes the Chilkat API to have been previously unlocked.

Dim success As Boolean

// We wish to compute the SHA256 hash of the bytes 0x6C 0xF8 0xEA 0x51 0xE4 0xE0 0xF5 0x99 0xCF ...
Dim src As String
src = "6CF8EA51E4E0F599CF03EC8D58C3DCBC9C889A77FB2816B40DE25C2EC54E98A67EA517B"

Dim bd As New Chilkat.BinData
success = bd.AppendEncoded(src,"hex")

// The bd now contains the bytes 0x6C 0xF8 0xEA 0x51 0xE4 0xE0 0xF5 0x99 0xCF ...

Dim crypt As New Chilkat.Crypt2
crypt.HashAlgorithm = "sha256"
crypt.EncodingMode = "hex"

// Hash the bytes contained in bd, and return the 32-byte SHA256 hash as a hexidecimal encoded string.
Dim result As String
result = crypt.HashBdENC(bd)
System.DebugLog(result)
