(JavaScript) Encode Integer to Hex or Base64 using N Bytes

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.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var crypt = new CkCrypt2();

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

// Write the integer in 8 bytes using little-endian byte-order and return as hex
var bLittleEndian = true;
var s = crypt.EncodeInt(value,8,bLittleEndian,"hex");
// The output is: 5634120000000000
console.log(s);

// Now use big-endian...
bLittleEndian = false;
s = crypt.EncodeInt(value,8,bLittleEndian,"hex");
// The output is: 0000000000123456
console.log(s);

// Instead of hex, get the 8 bytes using base64.
s = crypt.EncodeInt(value,8,bLittleEndian,"base64");
// The output is: AAAAAAASNFY=
console.log(s);
