# otpgen

Library to generate TOTP/HOTP codes

## Installation

```

## Usage

Here is a sample demonstration

```go

package main

import (

	"fmt"

	"github.com/grijul/otpgen"

)

func main() {

	// Generate TOTP

	totp := otpgen.TOTP{

		Secret:    "testpass",

		Digits:    8,        //(optional) (default: 6)

		Algorithm: "SHA256", //(optional) (default: SHA1)

		Period:    45,       //(optional) (default: 30)

		UnixTime:  11111111, //(optional) (default: Current Unix Time)

	}

	if otp, err := totp.Generate(); err == nil {

		fmt.Println(otp)

	} else {

		fmt.Println(err.Error())

	}

	// Generate HOTP

	hotp := otpgen.HOTP{

		Secret:  "testsecret",

		Counter: 100, //(default: 0)

		Digits:  8,   //(optional) (default: 6)

	}

	if otp, err := hotp.Generate(); err == nil {
