And thanks for the answer!

Actually my problem is that with that token file, it shouldn't reach millions of tries (and therefore > 2 days) but only about 20,000 combinations... so there's obviously something wrong in the way I wrote the token file.

Hi everybody,

Short stroy long: I wanted to unlock my Bitcoin wallet to sell my BCH (~10BTC). I bought some 6 years ago, and now I'm trying to crack my password with btcrecover. I'm pretty sure it's a sentence, that I know (I unlocked my wallet once a few years ago to pay for my taxes) but there must be a subtle variation that I cannot find anymore. It's psychologically quite strange to have you from 6 years ago as your opponent !

So, well, my password is a sentence similar to "El cinco de mayo es para las personas que viven en Estados Unidos el equivalente del 16 de septiembre para los mexicanos." and I'd like to change a few words, such as:
  • 1st word: El el
  • 2nd word: cinco 5
  • 3rd word: Mayo mayo
  • ...
  • Last word: mexicanos. mexicanos

My goal is to test all the variants with btcrecover, so I've written a token file looking like this:
^1^El%s el%s
^2^cinco%s 5%s
^4^Mayo%s mayo%s
^18^mexicanos mexicanos. Mexicanos Mexicanos.

I've computed that there are around 20,000 combinations, however when I execute btcrecover with the following options:
./ --wallet wallet.dat --tokenlist tokens.txt --utf8 --min-tokens 18
it ends with the following error message: "at least 3,800,000 passwords to try, ETA > --max-eta option (168 hours), exiting"

I'm obviously doing something wrong, any help would be appreciated  Smiley

Besides, are you aware of BTC client changes that could have happened between 2012 and now, and that would impact Unicode passwords?

Have a great day! (Now trying to crack with passwordlist and --typos 3)
