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.

Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const crypt = try chilkat.Crypt2.init();
    defer crypt.deinit();

    // 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
    var b_little_endian: bool = true;
    var s: [:0]const u8 = try crypt.encodeInt(alloc, value, 8, b_little_endian, "hex");
    // The output is: 5634120000000000
    std.debug.print("{s}\n", .{s});

    // Now use big-endian...
    b_little_endian = false;
    s = try crypt.encodeInt(alloc, value, 8, b_little_endian, "hex");
    // The output is: 0000000000123456
    std.debug.print("{s}\n", .{s});

    // Instead of hex, get the 8 bytes using base64.
    s = try crypt.encodeInt(alloc, value, 8, b_little_endian, "base64");
    // The output is: AAAAAAASNFY=
    std.debug.print("{s}\n", .{s});
