I'm trying to check in on some BTC I stored in a blockchain.info wallet 4 years ago (12/2013). I can log into my account just fine, but the wallet with my coins still needs a private key. I've got a couple .aes.json files, but I haven't found any way to import them (best I found was something called "wallet-key-tool" that might work, but none of the passwords I tried did anything - could be bad password but could also be bad software).
I've also got a piece of paper with two sets of words: one with 29 words and one with 13. I'm pretty sure these are related to the blockchain.info wallet, but I can't find any reference to this sort of recovery phrase (everything seems to want 12 words these days).
Finally, the last option would be to do a mini brute-force attack on the key. I'm reasonably sure I could narrow the password options down to a few thousand - are there any command-line tools that can attempt to decrypt an .aes.json file and recognize when it worked or not?
I adapted https://gist.github.com/fcicq/3368495 to read from a file with a hundred thousand possible passwords. Turns out the wallet was double-encrypted, but this at least took care of the first layer, and then wallet-key-tool took me the rest of the way. Hooray!
