Compute Glacier SHA256 Linear Hash of a File

See more Amazon Glacier Examples

Computes the Amazon Glacier SHA256 linear hash for a file. Swift

func chilkatTest() {
    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let crypt = CkoCrypt2()!

    // The "linear hash" is simply the SHA256 hash of the file bytes.
    crypt.hashAlgorithm = "sha256"

    // Return the hash in lowercase hexidecimal format.
    crypt.encodingMode = "hexlower"

    var linearHashHex: String? = crypt.hashFileENC(path: "qa_data/jpg/penguins.jpg")
    print("SHA256 linear hash = \(linearHashHex!)")
