Are you trying to recover something with this payload?
Is that payload comes from wallet.aes.json from the old blockchain.info that thing is encrypted.

However, you can able to decrypt it through brute-force usually they use BTCrecover tool (https://github.com/gurnec/btcrecover) to decrypt this wallet.

If this is your wallet why not recover your wallet through Email or walletID?

I don't use that wallet, but judging by this support article (https://support.blockchain.com/hc/en-us/articles/4555924189212-What-do-I-do-if-I-forgot-my-password-), there isn't much you can do if you forgot your password.
What happened with your seed phrase? You should be able to recover your wallet using that recovery phrase.

haha... yeah.. iknow i sould be able to recovery with my recovery phrase. But i didn't write it down so the only possibilities are bruteforcing or make a wordlist with known passwords.

It seems that blockchain wallets remove the forgot password option from their recovery page so there is no way to get the password through their site.
Even installing or hosting the blockchain.info wallet on your PC seems it won't work as the other people said from here https://github.com/blockchain/service-my-wallet-v3/issues/320

Do you have the wallet.aes.json file? It seems brute-forcing this file is the only one you can do to recover your password and decrypt this file.

Bitcoin2John can only read Bitcoin Core (and derivative) wallets. It can't read blockchain.com wallets and obtaining an equivalent hash from the blokchain.com wallets is of no use since Hashcat can't understand the hash format either [for brute-force purposes].

Yes i have the wallet.aes.json file.

Yes i have the wallet.aes.json file.

Then that's the only file that you need for brute-forcing you can use the BTCrecovery tool link below.

- https://github.com/gurnec/btcrecover

If your PC is low specs it may take months or years depending on how long your password is.
But if you have a rig with GPU you can speed up the brute-forcing process check this link below.

Wrong link. That software is 5 years out of date. Use this up-to-date (and faster/more efficient) fork instead: https://github.com/3rdIteration/btcrecover/

Here are the instructions to follow to use btcrecover to attempt to decrypt this wallet file: https://btcrecover.readthedocs.io/en/latest/Usage_Examples/2020-05-08_Recovering_Blockchain_Wallet_Passwords/Example_Recovering_Blockchain_Wallet_Passwords/

You can skip the step regarding downloading your wallet file since you already have the wallet.aes.json file. You'll need to create either a password list or a tokens list, depending on how much you know about the password. See more info here: https://btcrecover.readthedocs.io/en/latest/tokenlist_file/. I can help you construct this if you get stuck.

How much can you remember about the password you used? Length? Letters, numbers, symbols? Any words or phrases? If you can't remember anything at all, then you are probably wasting your time even trying unless the password you used is very weak.
