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.

    var crypt = new chilkat.Crypt2();

    // 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);
