Already did that, that's another proof that my password is correct, even though when I try to use it in the site I get the "Cannot decrypt wallet, wrong password" message.
But what can I do with that file? Can I use it to transfer the wallet to another one?
It seems you forgot some character from your password or you put an extra character from your password.
Why not try to brute-force the wallet to find the right password for this file "wallet.aes.json" there is a free tool that you can use to recover the right password.
Check this tool
https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#btcrecover-tutorialSupported blockchain wallet (v1-v3 wallet formats, both main and second passwords)
It sometimes happens to me that I remember the right password but didn't work but it solves my problem when I use a brute-force tool and see some extra character on my password that I forgot.
