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.

React Native

import { Crypt2 } from '@chilkat/react-native'

function chilkatExample() {
  const crypt = new Crypt2();

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

  // Write the integer in 8 bytes using little-endian byte-order and return as hex
  let bLittleEndian = true;
  let 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);
