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.

Indeed, you read it correctly, there's no lower case "l" in bitcoin addresses nor zeros nor upper case O.  See here for more background on it: https://en.bitcoin.it/wiki/Base58Check_encoding

Hey thanks for that - much appreciated.

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?)

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....

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........

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.

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.

Eg:-

Code:
"path\to\oclvanitygen.exe" -D 0:0 -k -o anything 1Prefix

Given that there are two bitcoin addresses per private key, that if you are iterating through private keys pseudo-randomly (i assume this is what vanitygen does, at the end of the day), it does seem that you may as well look at both the addresses each time you calculate a point on the curve for a given private key...

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.

Did you update your video drivers?  (Hint: Version 12.10 works best - saves Delta from stalking you in the middle of the night)

...and
Code:
-D 0:0 -D 0:1 etc
are your friends....

...and
Code:
-S
safe mode may be fractionally slower, but it'll work until you've had some sleep.

The only thing I'm not sure is if it searches for all lines listed or does them one at a time?

Has the HD5870 been superseded yet as the best vanity miner? I bought mine for $100 and it gets a whopping 30Mkey/s out of the box. Have newer gen GFX cards surpassed this?

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 Wink
