I’m helping a friend recover a very old seed (Summer 2012). There’s likely no coins on it, and if there are it’s not many, but it’s more of a challenge kind of thing.
Here’s the situation (what he can remember, which is not much):
1. He generated a seed or wallet or password using something he can’t remember (we suspect it might have been a [blockchain.com](https://blockchain.com) password, or an electrum seed, mostly based on the date), of unknown length. He remembers having had to select an address from a list of addresses, which sounds more like an electrum thing than a [blockchain.com](https://blockchain.com) thing.
2. He then generated a list of 100 words (not sure where he got the words), and “hid” the key in those words. We know they were kept in order, but do not know if they were kept adjacent (his best recollection is they were not).
At one point we suspected [bitaddress.org](https://bitaddress.org), but looking at the date of his 100 words file, it was created \*right\* before bitaddress supported specifying one’s words (versus just random keys)
I’m writing tools for him to bruteforce possible solutions/combinations, but any information I could get about what would be “possible” at the time, would be helpful.
How would I go about finding the Summer 2012 list of words for electrum (has it changed since or would the current one be good?), to do the same sort of analysis.
Aside from [blockchain.com](https://blockchain.com) and electrum, is there any other candidate for what he could have used to generate his seed/key?
We can’t figure out how he generated the 100 words, any hints of any tools back at that time that would have done it for him?
Any ideas of how to make progress on this?
(any help that participates in solving the puzzle will result in a small crypto reward from my pocket, no matter if the wallet contains coins or not).
(no PM contact obviously. also, my friend won’t share the list of words even with me, so you have no hope of getting it from me…)
