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. Node.js

    // 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 ...

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