Restoring / buying paper wallets, WIF or QR codes

[math09183]

I offer my help in restoring paper wallets (damaged, partial WIF, broken QR code etc.), negotiable fee (depends on amount and amount of work). In any case, PM or email me.

What makes you trustworthy to handle private keys? The fact that you spam the same topic on 3 different boards doesn't really inspire confidence.

I have a XLM private key written down with some mistakes. It's not mine, I tried for someone 3 years ago, but couldn't find the correct key. Any ideas on that (without me sending the key of course)?

I would try an approach similar to this, if you are certain that the amount of errors is small: https://bitcoin.stackexchange.com/questions/98944/how-can-i-recover-the-missing-end-of-my-private-key

Sadly for Stellar there aren't as many good tools as for BTC (e.g. the glorious BTC-Recover).

Honestly speaking never heard of that s*coin. Which format it is? WIF? If yes, how many characters missing?

I don't know how many mistakes are made, and I don't know where they're located.
I tried Conding Enthusiast's StellarCracker 3 years ago, but it didn't find it. The private key could very well have more than one mistake on more than one location.
There's a couple hundred bucks (at current exchange rate) in it for me (or anyone who helps) if I ever manage to crack it. The deal was the owner gets 90%.

I found back my comment in my final email to the guy: "I think you just made too many mistakes writing it down the first time.".

I took a look at StellarCracker and the logic behind it, I think I may play with it. I will modify my WifSolver to work with base32 and maybe extend the number of searches/replacements. Just confirm - you have all the characters but checksum is wrong, right?

I don't know what's wrong (but I do have the address).

I have prepared a simple tool based on my WifSolver, now it supports only "rotation" (checking 1,2,3... misspelled characters), check could be done for any correct KEY or for the given AccountId, as you said you have the expected one. I will add "SEARCH" worker, for checking a given/all characters on the specific positions, but I think it is less important now.
Later I will prepare ReadMe, but for now you may just launch it:

Code:

java -jar stellarSolver.jar ./examples/example_ROTATE.conf

In examples/ folder you will find how to launch it - by default it checks 1 and 2 mistakes, you may indicate if you want more (KEY line, after comma). The last line - expected AccountId.

This looks promising, it's running now (in a VM with no internet access) for 3 incorrect characters. I assume it checks 3 characters at random locations, right?
The next possibility would be more than 3 missing characters, or a "shift" of an entire block of characters to the left or right.
