Generator and parser for redemption codes

This project is a generator and parser for redemption codes. It can generate unique redemption codes based on an increment id, and parse the redemption codes back into the original increment id. This project is suitable for applications that require the generation of large numbers of unique codes in a short period of time.

You can get the project by using the go get command:

go get github.com/ZainCheung/cdk

In your Go code, you can use this project as follows:

package main

import (
	"fmt"
	"log"
	"github.com/ZainCheung/cdk"
)

func main() {
	// get a new random secret table
	randomSecret, err := cdk.GenerateRandomSecret()
	if err != nil {
		return
	}
	var CharTable = []string{
		"A", "B", "C", "D", "E",
		"F", "G", "H", "J", "K",
		"L", "M", "N", "P", "Q",
		"R", "S", "T", "U", "V",
		"W", "X", "Y", "Z", "2",
		"3", "4", "5", "6", "7",
		"8", "9",
	}
	c := cdk.New(randomSecret, CharTable)
	// get a code from an id
	code, err := c.Generate(100001)
	if err != nil {
		log.Fatalf("Generate returned an error: %v", err)
	}
	fmt.Println("Generated code:", code)
	// get an id from a code
	id, err := c.Parse(code)
	if err != nil {
		log.Fatalf("Parse returned an error: %v", err)
	}
	fmt.Println("Parsed id:", id)
}

In this example, we first generate a random secret table, then create a new Generater object with the secret table and a character table. We then use the Generate method to generate a redemption code based on an increment id, and the Parse method to parse the redemption code back into the original increment id.

The Generater in this project is highly efficient. In benchmark tests, it was able to generate 1,000,000 redemption codes in approximately 3 seconds. This makes it suitable for applications that require the generation of large numbers of unique codes in a short period of time.

Please note that actual performance may vary depending on the specific hardware and software environment.
