The grue lurks in the darkest places of the earth. Its favorite diet is adventurers, but its insatiable appetite is tempered by its fear of light. No grue has ever been seen by the light of day, and few have survived its fearsome jaws to tell the tale.

AFAIK there are no tools that do this. You will have to make one yourself.

Hey guys, I just found an old paper wallet. (I have only printed out private key and the bitcoin address) But there are a few letters or numbers that I can't read anymore. Now I need a tool where I can first enter the private key with the letters or numbers I don't know anymore... in this format: 5HpHag-65TZ-G1PH3CSu63k8Dbp-D8s5ip-nEB3kEsreAnc-uDf After I entered this I want to enter the letters or numbers that can be possible or I can choose all letters or numbers to check. Then I want to enter the bitcoin address which would be for this example: 1EHNa6Q4Jz2uvNExL497mE43ikXhwF6kZm Now the tool should check every private key that might be possible from my selection. I hope you can help. Best regards, Patrick Bitcoin Address 1EHNa6Q4Jz2uvNExL497mE43ikXhwF6kZm Bitcoin Address Compressed 1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH Public Key (130 characters [0-9A-F]): 0479BE667EF9DCBBAC55A06295CE870B07029BFCDB2DCE28D959F2815B16F81798483ADA7726A3C 4655DA4FBFC0E1108A8FD17B448A68554199C47D08FFB10D4B8 Public Key (compressed, 66 characters [0-9A-F]): 0279BE667EF9DCBBAC55A06295CE870B07029BFCDB2DCE28D959F2815B16F81798 Private Key WIF 51 characters base58, starts with a '5' 5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf Private Key WIF Compressed 52 characters base58, starts with a 'K' or 'L' KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M7rFU73sVHnoWn Private Key Hexadecimal Format (64 characters [0-9A-F]): 0000000000000000000000000000000000000000000000000000000000000001 Private Key Base64 (44 characters): AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAE=

5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf
OP and you: 5HpHag-65TZ-G1PH3CSu63k8Dbp-D8s5ip-nEB3kEsreAnc-uDf 5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf I'm curious: how did you do this? 5 digits isn't that much, so an altered version of vanitygen could brute force it in seconds. But do you just happen to have that lying around?

you can do it at https://www.bitaddress.org/but it will take you a long time to exploit all the feasible solution. about 570000 possibility withe these five missing letters good luck

I could probably throw together a C program that would do this for you. Do you have the ability to compile and run a C program?
If not, I might also be able to put together something in node.js

Compile this code: http://pastebin.com/S8WARrRnThis code is for address with 5 unknow "-" chars!! First set your address to 58. line, and compile the code (you need openssl dev installed, apt-get install libssl-dev): gcc -o recovery recovery.c -I /usr/include -Wall -lssl -lcrypto -O2 run it ( ./recovery ), and stop with ctrl+c, you got 5 "index: XX" lines. Modify the "define C_X_INDEX" lines in the code (line 49-53). Compile again. Run again and wait, get a coffee, or 10.

What does this output mean? When it says Test: 1A, what is it doing? Is it searching for the all possibilities on the 3 dots that start with A1, so it will stop at Tz? 5HpHag-65TZ-G1PH3CSu63k8Dbp-D8s5ip-nEB3kEsreAnc-uDf 5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf
"Test 1A" means: testing this privkeys: 5HpHag 165TZ AG1PH3CSu63k8Dbp *D8s5ip *nEB3kEsreAnc *uDf there are 58*58 (=3364) so groups, with your cpu (~2 sec/testgroup) you get the result about 2 hours. What doIf I'm right on this, it's a bit slower than vanity gen, doing 62^3=238328 keys in 2 seconds. Vanitygen does 3 times more on 2 cores.
i dont know vanitygen, how do you run it to test this keys?

Yes, normaly I can run a C programm. It would be nice if you can throw a programm togehter. No problem. I'll put something together this weekend and test it for a few days next week to see how good I can get the performance. In the meantime if you find another copy of your private key, or manage to remember what the values were, just let me know so I don't waste time on it.

Thanks. I edited my post the same time you posted this. You say 58 where I assumed 62. I didn't realize until now the private key excludes the same characters that are excluded from the address. i dont know vanitygen, how do you run it to test this keys?
Vanitygen searches random private keys until it finds an address with a certain prefix. Example: 1Loyce. Annoyingly, it segfaults since I've (re)installed libssl-dev. In the meantime if you find another copy of your private key, or manage to remember what the values were, just let me know so I don't waste time on it.
elbandi already posted a working program.

Top guy DannyHamilton is, one of the best here. OP you are lucky to have found a poster who is willing to do this for you. Anomgst all the bull shit & scamming that goes on here it's good to see there are some good people here.

Would it be possible to write similar program to work with compressed ones ?

Sure, here is the universal version: http://pastebin.com/gPzBp6u3it recognize the compression type from the first char. if the first char is a missing char, you have to set the compression type by manual ( compressed = 0; or compressed = 1;) tips are welcome: 1JsU1mfK3qxC37JoFiVhvi3KoA7ceUaMrZ

Unfortunately not. You would have been able to restore a few chars, but definitely not 20. By the way, if you don't have an offline backup (not stored on your computer), you don't have a backup at all. Any incident affecting your computer (electrical short, ransomware, .. ) could have lead to a loss of the private key. Storing a backup on the same device as the wallet is not a backup at all.

Was your private key saved in a file before your kid fucked it up? If that's the case, you may be able to restore an earlier version of said file; and with some luck, it will contain the whole privkey.
