Hi. Great tool. Really helped me.
I just don't know why base64 here is different than other standards I tried.

Just please change length of generated code verifier from 43 to 128.
It is on standard and on WSO2 gateway this was issue and it was really hard to figure out, where is problem.

Thank you.

Hi, thanks for pointing this issue out. I just updated the length to 128. It should be good now.

Great tool, really. Helps me a lot

According to the same standard @antoninbouchal mentioned, possible characters also contain "-" / "." / "_" / "~"

You are right, thanks for pointing out. I fixed with those characters.

Note than Math.random is not cryptographically secure, so you really shouldn't use it for this purpose. I recommend using the code here instead: https://github.com/aaronpk/pkce-vanilla-js

It has the added bonus on not having any dependencies, ie you don't need CryptoJS.

Thanks for sharing
I writed another PKCE generator without external libs (vanilla js) https://gist.github.com/bilelz/4449430eb1070fc34b8ebfaf5fb9f9b5

Thank you all for sharing vanilla JS version without external libraries. I created this demo mainly to demonstrate the functions required to generate the challenge.
