Example: Crypt2.GenRandomBytesENC method

Shows how to use the GenRandomBytesENC method to generate a specified number of random bytes and return them as a binary encoded string, such as in base64 or hex format. Swift

func chilkatTest() {
    let crypt = CkoCrypt2()!

    // Example of a some of the binary encodings supported by Chilkat.

    // Internally uses the Fortuna cryptographically secure random number generation algorithm
    // auto-seeded from a secure source of entropy that depends on the OS.

    crypt.encodingMode = "hex"
    var s: String? = crypt.genRandomBytesENC(numBytes: 8)
    print("Uppercase Hex: \(s!)")

    crypt.encodingMode = "hex_lower"
    s = crypt.genRandomBytesENC(numBytes: 8)
    print("Lowercase Hex: \(s!)")

    crypt.encodingMode = "base64"
    s = crypt.genRandomBytesENC(numBytes: 8)
    print("Base64: \(s!)")

    crypt.encodingMode = "base64url"
    s = crypt.genRandomBytesENC(numBytes: 8)
    print("Base64Url: \(s!)")

    crypt.encodingMode = "base58"
    s = crypt.genRandomBytesENC(numBytes: 8)
    print("Base58: \(s!)")

    crypt.encodingMode = "base32"
    s = crypt.genRandomBytesENC(numBytes: 8)
    print("Base32: \(s!)")

    crypt.encodingMode = "decList"
    s = crypt.genRandomBytesENC(numBytes: 8)
    print("Decimal List: \(s!)")

    // Sample Output:

    // Uppercase Hex: 1BA0E87915C3B429
    // Lowercase Hex: 1e1638a1c7996c58
    // Base64: 1lV0I/su5lg=
    // Base64Url: Zq7DU0nukLk
    // Base58: foUVWUjAT6e
    // Base32: LHV5RV4HRCLW2===
    // Decimal List: 168,55,214,82,93,154,191,164
