I suggest that you give valid proof of ownership. Otherwise, it would be highly suspicious.
Who in their right mind would think about selling a wallet file that has 22.8 BTC in it for just 1 BTC, even where there is the slightest chance to have it cracked?
And who would buy an encrypted wallet file that even the owner has completely failed to remember the password?
My guess, OP, just forgot to make this post today. It well suits the theme of the day.
