This cipher is useful for obfuscating 32-bit values in the same size output space.

This can be useful for exposing an incremental ID externally without leaking sequence or value.

Usage

package main

import (
	"fmt"

	"github.com/jmhobbs/skip32"
)

func main() {
	key := [10]byte{0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09}
	fmt.Println(skip32.Encrypt(key, 500))
	// 499237320

	anotherKey := skip32.KeyFromSlice([]byte("this is a string"))
	fmt.Println(skip32.Encrypt(anotherKey, 500))
	// 1928549585
}
