Alternatively from the crypto-recovery posted above, you can also get your wallet.aes.json as a text by following the guide below
Try to get your wallet.aes.json by pasting your walletID to this URL:
https://blockchain.info/wallet/WALLET_ID?format=json
Replace "
WALLET_ID" with your Wallet ID, do not change anything like the punctuation marks.
If you didn't set 2FA, the URL will display your wallet.aes.json in txt format (
if you have 2fa, use the method below).
With it, create a "
wallet.aes.json" file and paste the text using a txt editor, then decrypt it using decryption tools.
This one should work:

Wallet Import Format), it's in base58 form.
If you successfully decrypted the wallet file, you can convert the base58 private keys into WIF by using base58 decoder and then convert the result ECDSA PrvKey into WIF (
compressed) to be able to import/sweep it to other wallets.
Another method to get your wallet.aes.json file is to use btcrecover's extract-script:
download-blockchain-wallet.py from
https://github.com/gurnec/btcrecover/tree/master/extract-scriptsI don't know if this will work on a new or HD account but worth trying. Once you get the wallet.aes.json your last step is to decrypt the wallet to get the private key.
