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. Go

    success := false

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

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

    bd := chilkat.NewBinData()
    success = bd.AppendEncoded(src,"hex")

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

    crypt := chilkat.NewCrypt2()
    crypt.SetHashAlgorithm("sha256")
    crypt.SetEncodingMode("hex")

    // Hash the bytes contained in bd, and return the 32-byte SHA256 hash as a hexidecimal encoded string.
    result := crypt.HashBdENC(bd)
    fmt.Println(*result)

    bd.DisposeBinData()
    crypt.DisposeCrypt2()
