(Swift 3,4,5...) Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password) ) )

Demonstrates how to compute:

Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password)))

    var password: String? = "secret"

    let crypt = CkoCrypt2()!
    crypt.hashAlgorithm = "SHA-1"
    crypt.encodingMode = "base64"

    // Generate a 16-byte random nonce
    let prng = CkoPrng()!
    let bd = CkoBinData()!
    prng.genRandomBd(16, bd: bd)

    // Get the current date/time in a string with this format: 2010-06-08T07:26:50Z
    let dt = CkoDateTime()!
    dt.setFromCurrentSystemTime()
    var created: String? = dt.getAsTimestamp(false)
    bd.append(created, charset: "utf-8")

    // This example wishes to calculate a password digest like this:
    // Password_Digest = Base64 ( SHA-1 ( nonce + created + SHA-1(password) ) )

    // First SHA-1 digest the password...
    var passwordSha1: String? = crypt.hashStringENC(password)
    // Append the 20 binary bytes of the SHA1 hash to bd, which already contains the nonce and created date/time.
    bd.appendEncoded(passwordSha1, encoding: "base64")

    var passwordDigest: String? = crypt.hashBdENC(bd)

    print("Base64 password digest = \(passwordDigest!)")
