Subject: brute force unknown chars

Hello,

Can anyone please help me as I can't figure out if this is even possible?

Example: I know the password begins with "Password" but is 12 characters
long.
So, I would need to brute force the last 4 char using thecustom.chr that I
created.

Can someone please help me with this?

Thanks
