Encode Integer to Hex or Base64 using N Bytes

See more Encryption Examples

Demonstrates how to write an integer to N bytes (little-endian or big-endian) and return the bytes in any encoding such as hex, base64, etc.

Note: This example requires Chilkat v9.5.0.77 or greater.

Swift

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

    // 1193046 decimal is equal to 0x123456 hex.
    var value: Int = 1193046

    // Write the integer in 8 bytes using little-endian byte-order and return as hex
    var bLittleEndian: Bool = true
    var s: String? = crypt.encodeInt(value: value, numBytes: 8, littleEndian: bLittleEndian, encoding: "hex")
    // The output is: 5634120000000000
    print("\(s!)")

    // Now use big-endian...
    bLittleEndian = false
    s = crypt.encodeInt(value: value, numBytes: 8, littleEndian: bLittleEndian, encoding: "hex")
    // The output is: 0000000000123456
    print("\(s!)")

    // Instead of hex, get the 8 bytes using base64.
    s = crypt.encodeInt(value: value, numBytes: 8, littleEndian: bLittleEndian, encoding: "base64")
    // The output is: AAAAAAASNFY=
    print("\(s!)")
