I have a Blockchain.info backup (json file without password) i opened in chrome browser, it looks like this:
That doesn't look like "
json", more like the "
base64" encoded payload.
Theoretically, if it's not encrypted (
wallet.json), opening it with any text editor is enough to see the private keys in bare base58 format next to every "
priv:" lines.
Since you claimed that there's no password, decoding that base64 string should result with readable text containing the data I mentioned including master keys if the wallet is HD.
You said "
I Have", but didn't mentioned where you got it from.
Is it from someone that claimed that it's a blockchain(
dot)info backup or you downloaded it from the wallet yourself?
According to this post is stack exchange, wallet.aes.json may have this kind of data
https://bitcoin.stackexchange.com/questions/115557/what-is-the-correct-format-for-wallet-aes-jsonIt seems Blockchain.info / blockchain.com's custodial wallets have used several different formats.
...
blockchain-v0.0-wallet.aes.json looks like base58 encoded data:
