Proof Key for Code Exchange (PKCE)

Generate PKCE verify and challenge code.

Instillation

go get github.com/akshaybabloo/pkce/v2

Usage

There are two ways of doing this

Your own string

You can put in your own string, example:

package main

import (
	"fmt"

	"github.com/akshaybabloo/pkce/v2"
)

func main() {
	p := pkce.Pkce{
		RandomString: "45d7820e694481f399e7fb9c444f0cb63301a7254d1401443835d9af2c9a6a5ec5b243c3470feb945336025964ef05c8d2f0e44baf76762ba6136914",
	}

	fmt.Println(p.VerifyCode())  // This is optional
	// Output: 45d7820e694481f399e7fb9c444f0cb63301a7254d1401443835d9af2c9a6a5ec5b243c3470feb945336025964ef05c8d2f0e44baf76762ba6136914
	
	fmt.Println(p.ChallengeCode())
	// Output: iQoF8w9kq5RnuMdisRXypyOoMCF7FGz-ro7dwHjC28U
}

When you enter your own string, calling p.VerifyCode() is optional

Let us generate one for you

You can let the module generate a random string for you, but the length should be more than or equal to 43 and lest and or equal to 128.

package main

import (
	"fmt"

	"github.com/akshaybabloo/pkce/v2"
)

func main() {
	p := pkce.Pkce{
		Length: 128,
	}

	fmt.Println(p.VerifyCode()) // This is optional
	// Output: 45d7820e694481f399e7fb9c444f0cb63301a7254d1401443835d9af2c9a6a5ec5b243c3470feb945336025964ef05c8d2f0e44baf76762ba6136914
	
	fmt.Println(p.ChallengeCode())
	// Output: iQoF8w9kq5RnuMdisRXypyOoMCF7FGz-ro7dwHjC28U
}

Note: Calling p.VerifyCode() optional, but calling it after p.ChallengeCode() will reset pkce.RandomString
