I need help getting into my veracrypt. I have located all 3 keyfiles i needed (stupid i know) and I know the basics of my password but i've legitimately forgotten what it was exactly, and due to me being silly/paranoid i didn't write it down.

So, I know its a phrase, let's say it's Chan

and I know I wrote it down in a special way, like
ChanCHAN

but this could also be:
>Ch4nChan
>ChanCH4N
>ChanCHAN
>ch4nCH4N
and what-not. The actual password has about 3 variations on what it could be - but here's the actual difficult part.

There's 4 symbols on either side. I know what both of the used ones are, but not the actual order. I tried getting chatgpt to write it out for me but it tarded out and just wouldn't give me a correct answer.

How can I basically hack into my own vault? I can manually write a list of every possible password (it's just a lot to keep track of and would take a while) so hopefully you guys can give me a way to automate it.

Thanks guys
