Hash the Contents of a File (SHA256 and other hash algorithms)

See more Encryption Examples

Demonstrates how to hash the contents of a file using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc. Swift

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

    let crypt = CkoCrypt2()!

    // Choose the hash algorithm.
    // Can be  "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".
    crypt.hashAlgorithm = "sha256"

    var hashBytes: NSData
    hashBytes = crypt.hashFile(path: "qa_data/jpg/starfish.jpg")

    // Let's examine the hash as a hex string.
    let sb = CkoStringBuilder()!
    sb.appendEncoded(binaryData: hashBytes, encoding: "hex")
    print("SHA256 hash = \(sb.getAsString()!)")
