Trying to recover a blockchain.info wallet from 2013 w/ a 29 (or 13?) word phrase
I ended up adapting gist.github.com/fcicq/3368495 to read from a file with a hundred thousand possible passwords (which I generated by permuting the inputs I was pretty sure I used to generate it in the first place).

It turns out that 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, by trying a few passwords by hand (once I found out the first password, the second was easier to guess/recall).
