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.

Chilkat2 Java

import com.chilkatsoft.chilkat2.Crypt2;

public class ChilkatExample {

    public static void main(String[] args) {
        Crypt2 crypt = new Crypt2();

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

        // Write the integer in 8 bytes using little-endian byte-order and return as hex
        boolean bLittleEndian = true;
        String s = crypt.encodeInt(value, 8, bLittleEndian, "hex");
        // The output is: 5634120000000000
        System.out.println(s);

        // Now use big-endian...
        bLittleEndian = false;
        s = crypt.encodeInt(value, 8, bLittleEndian, "hex");
        // The output is: 0000000000123456
        System.out.println(s);

        // Instead of hex, get the 8 bytes using base64.
        s = crypt.encodeInt(value, 8, bLittleEndian, "base64");
        // The output is: AAAAAAASNFY=
        System.out.println(s);
