create-address-db.py

trying to create a database of bitcoin addresses, but i keep getting an error all the time, it appears someone else has already posted the error,

python create-address-db.py --force Parsing block files ... Traceback (most recent call last):#####################################################################################################-----------] 266,508,985 addrs. 1:08:53, ETA: 0:05:59 File "create-address-db.py", line 72, in addressset.create_address_db(args.dbfilename, blockdir, args.update, progress_bar=not args.no_progress) File "/home/djones/btcrecover-master/btcrecover/addressset.py", line 376, in create_address_db sigscript_len, offset = varint(block, offset + 36) # skips 32-byte tx id & 4-byte tx index File "/home/djones/btcrecover-master/btcrecover/addressset.py", line 279, in varint b = ord(data[offset]) IndexError: string index out of range

is there a fix for this?

is there no update for this, i'd really like to create a database of addresses, i think while my friend was creating the secondary password on the blockchain he may have pasted in a bitcoin address as his password, so this would be ideal to use

This bug was fixed about 30 days ago in version 0.1.3. Please run create-address-db.py -v and if your version number is less than 0.1.3, please upgrade.

Even though it's called an "address database", it really isn't one... it's an approximate set membership or approximate membership query filter, similar to a cuckoo, Bloom, or quotient filter. Once it's built, there's no way to extract full addresses from it, it can only be used to test if a given address is (very likely) in it.

It's probably possible to make some quick-and-dirty changes to the code to get it to parse the blockchain and save full unique addresses to a text file, which sounds like what your trying to accomplish, but as it currently is, I don't think it would be helpful to you....

(Also, keep in mind that it only supports P2PKH addresses (those which start with a 1) and it can only fetch addresses which have received funds at least once.)

thank you, running it again now

was able to successfully create the database this time, but when trying to use SQLite3 to read the database, it says its either encrypted or not a database

sqlite> .dbinfo database page size: 25971 write format: 115 read format: 32 reserved bytes: 100 file change counter: 1650553701 database page count: 218790695 freelist page count: 1751081593 schema cookie: 1952805671 schema format: 975189036 default cache size: 539457125 autovacuum top root: 1920166255 incremental vacuum: 1601074540 text encoding: 1848064544 user version: 824975399 application id: 1818190180 software version: 808475768 number of tables: 0 number of indexes: 0 number of triggers: 0 number of views: 0 schema size: 0 sqlite> .tables Error: file is encrypted or is not a database

i thought i'd be able to use this script to create a list of every bitcoin address, then use them to check if my friend copied and pasted a bitcoin wallet address as his password while he was trying to purchase an airline ticket with bitcoin, now its got a secondary password and he has no idea what it is, please advise if i am using this correctly or something went wrong,

cheers

As I said...

Even though it's called an "address database", it really isn't one...

I just threw this script together from existing code in btcrecover (right-click, save link as...). If you place it into the same directory as btcrecover and run it, it should create a text file containing each P2PKH address that has received funds in the blockchain (excluding a few clearly invalid addresses). I barely tested it at all, so it's strictly "run at your own risk", but it seems to work for me. The output file will be somewhere around 10ish gig.

You can use this with btcrecover's --passwordlist (and --blockchain-secondpass) to see if the second password is a P2PKH (starts with a 1) address.

Good luck!

hi there,

thanks a lot for the script, but i have a feeling because the transaction wasn't completed with bitpay, the address would be one with a zero balance, so i guess i'm pretty much screwed if he infact used a bitcoin address as his second password on the blockchain, its unfortunate for him as he wont ever recover his money, i sold him my bitcoin miners and he had close to 2 bitcoins in there

[coinhunters]

what is the general costs to recover blockchain second password?

I may be able to find the password you lost. Do you need help with your login?
