Ok so my friend recently wanted me to help him with his lost password he said he knows most of it but there are a few characters which he has either mistyped or forgotten. But because we live far away from each other I suggested that he doesn't upload his wallet.dat on the internet and use the pywallet and dump the keys etc (so he doesn't have to worry about losing any of it)
However, I Haven't got much knowledge of what to do when I receive that information. Can someone let me know what to do with the information he gave me from the pywallet dump?
Thanks in advance.
Most importantly, please be aware that the information which pywallet dumps is just as sensitive as the wallet.dat file itself, so they both should be treated carefully!
If you have a decent idea of what the password contains, you have at least some chance of recovering the wallet file. There is an open source tool,
btcrecover, over here that may help (full disclosure: I'm the author). The
tutorial is here. Also,
this thread has a wealth of information on the subject.
If you're worried about transferring wallet information over the Internet, that tool has a
potential solution for that issue as well. If you have any questions or need assistance with it, please let me know.
