How find a privkey for a complete address ?
i use
Code:
"path\to\vanitygen.exe" bitcoinaddress
but see error the address is too long .
See how the bit you quoted says 'unhappy'?  That's a bit of an understatement.. see: https://en.bitcoin.it/wiki/Vanitygen#Use_of_vanitygen_to_try_to_attack_addresses

That said - yes, there's a limit on the length as the vanity cannot include the error correction portion of the address, so you'd have to feed it the address minus the error correction portion.

Hi there,

I saw on the opening page

Quote
try "vanitygen -r [Ww]iLL"

(no need to use [Ii] and/or [Ll] because l (small L) and I are not in base58, I think.

EDIT: found one in seconds: 1NZED7AR8hbwiLLkTWwXgZvM89FZqFiXnj

Would that mean I can't put

Code:
vanitygen -f work.txt -o dump.txt

( work.txt ) Timelord

into a search only TimeLord ?

And also, If I'm looking for Timelord2067 I'd actually have to put TimeLord2o67 (small "oh' Oscar after the "2")

Thanks for looking.

I don't understand your explanations very well .... my question is what are the command lines for finding privkey for a complete address ?

I have a quantum computer that capable of looking through 1000 billion keys per micro second. i want to attack this address 1Cii2e2wGejfrRHRCbaYTzmyPLpJwGvsgD what are the Instructions at vanitygen ?

Closest you'll get with unmodified builds is:
Code:
vanitygen.exe -k -o output.txt 1Cii2e2wGejfrRHRCbaYTzmyPLp
Technically that's missing the last 3 characters 'JwG' (the other 4 are the checksum), but one out of every 200,000 addresses or so in the resulting output.txt file should be correct.  Have fun with your quantum computer.  You should have gone with more ridiculous numbers, though.. it would still take 3.3E24 years on average.

You know there's no BTC in this wallet https://blockchain.info/address/1Cii2e2wGejfrRHRCbaYTzmyPLpJwGvsgD (and it only every had about $50 at most ever?)

Thanks!
Nice topic to research.
the mayor changes will only have to be made in the function:
void *vg_thread_loop(void *arg).
In stead of the two options compress and uncompressed a combined flag could to be introduced/added as a valid command line flag.
When combined is active, only calculate (uncompressed) EC points for half the buffer.
Fill the other half with the equivalent compressed points.
for all other calculations use same flag to switch halfway between postprocessing (un)compressed settings.
The final address checks can stay the same.
In theory.... at least.

It will take a bit more work than just porting the example python code........

With a Quantum Computer, you'd be better off mining BitCoin blocks. 1,000 Billion is a Trillion BTW, thought you'd like to know that and a micro second... Well.... that's just silly.... No, there's no known quantum algorithm for solving a SHA256 hash. It would also be useless for address reversal (except possibly with reused addresses) since the pubkey isn't known, just the hash, until the first spend from said address. I'm also not sure if EC is breakable on a quantum computer (Shor's algorithm has a discrete log variant but I'm not sure if it's applicable here) I have recently become active again after a long period of inactivity. Cryptographic proof that my account has not been compromised is available. Muhammed Zakir Hero Member Offline Activity: 560 Merit: 504 I prefer Zakir over Muhammed when mentioning me!  August 24, 2015, 01:27:37 PM I have 5 prefix letters , what is the command line for find at least a BTC address for it ? Case-sensitive prefix search: Code: "path\to\vanitygen.exe" 1Prefix Case-insensitive prefix search (faster): Code: "path\to\vanitygen.exe" -i 1Prefix Case-sensitive prefix search but not limited to 1 match: Code: "path\to\vanitygen.exe" -k 1Prefix Case-sensitive prefix search but not limited to 1 match and saves all matches to a file: Code: "path\to\vanitygen.exe" -k -o anything 1Prefix Note: If you want to save all matches to a file in the same folder Vanitygen is, specify the path to directory. Eg:- "path\to\vanitygen.exe" -k -o "path\to\anything" 1za Edit: Searching for compressed key is faster than uncompressed key. Download Lifeboat's vanitygen. See https://bitcointalk.org/index.php?topic=301068.0. Also, see https://bitcointalk.org/index.php?topic=25804.msg10590011#msg10590011. Case-sensitive prefix search but not limited to 1 match and saves all matches to a file (compressed): Code: "path\to\vanitygen.exe" -k -F compressed -o anything 1Prefix What are command lines for oclvanitygen ? does oclvanitygen use graphic card for computing ? and this is faster than vanitygen ? Commands are same except you will have to select OpenCL device using -D command. If you have only one OpenCL device and you did not specify, Oclvanitygen automatically chooses the device. Else, it will give you an error.

Only the initial key position is random, then vanitygen just increments the key by one for each additional address search. There is little cost to be saved there. wicks Newbie Offline Activity: 28 Merit: 0  August 27, 2015, 04:06:04 PM No matter what I try, I couldnt make it work with OpenCL on my computer.

Does it?  Specs-wise, it is a good bit faster than the HD5870.  I can't say I know which specs' changes would best align with vanitygen changes, but it doesn't seem unfathomable.  I'm sure it's not even removely the fastest; but hardware review sites don't generally test against oclvanitygen
