(Swift 3,4,5...) 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.
func chilkatTest() {
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
var success: Bool
// We wish to compute the SHA256 hash of the bytes 0x6C 0xF8 0xEA 0x51 0xE4 0xE0 0xF5 0x99 0xCF ...
var src: String? = "6CF8EA51E4E0F599CF03EC8D58C3DCBC9C889A77FB2816B40DE25C2EC54E98A67EA517B"
let bd = CkoBinData()!
success = bd.appendEncoded(src, encoding: "hex")
// The bd now contains the bytes 0x6C 0xF8 0xEA 0x51 0xE4 0xE0 0xF5 0x99 0xCF ...
let crypt = CkoCrypt2()!
crypt.hashAlgorithm = "sha256"
crypt.encodingMode = "hex"
// Hash the bytes contained in bd, and return the 32-byte SHA256 hash as a hexidecimal encoded string.
var result: String? = crypt.hashBdENC(bd)
print("\(result!)")
}
