Vanitygen: Vanity bitcoin address generator/miner [v0.22]

[ken3go]

what is the most interesting vanity address created so far? anybody care to share?

I have a good one running at 500Mkeys/s but it will take about 630k years, so I'll have to get back to you.

etotheipi found the all caps one in a week (he thought it would take 70 days).

Google that and you'll go down a rat hole of "longest" or "most unusual" addresses.

[hirozaki faraday]

I have always wanted to do a vanitygen for my cold storage, but I am too paranoid the program would have some sort of built in preset way to make an address the creator also has keys for. How am I supposed to know for sure? I just wish I could trust do it trust-less.

I just wish I could trust do it trust-less.

You can use ue split key for this. See (my thread) Pretty Addy Giveaway - part 2 for instructions.
With split key, it doesn't matter if someone else creates the address for you, or you don't trust vanitygen. As long as you keep your private keys offline all the time, it's secure.

If you also don't trust bitaddress.org, you'll need to use something else to create a private key.

I've been generating Ravencoin addresses but haven't been able to get one of them to import successfully.  Anyone had any luck with them? 

[LoyceV]

Vanitygen has a command that is not listed in the program options:

Code:

-F script

Actually, it is listed:

Code:

./vanitygen --help
-F <format>   Generate address with the given format (pubkey or script)

Amazing

I have to test this!

Code:

./vanitygen -F script 3test
Prefix '3test' not possible
Hint: valid bitcoin script addresses begin with "3"

I'm not sure what the requirements are exactly, but this works:

Code:

./vanitygen -F script 333333
Difficulty: 264104224
Pattern: 333333                                                                
P2SHAddress: 333333dirmCEYVJGZavhjt2fmWL15boJYx
Address: 12ZEW67DZX9LP1rNQq6bSnw1mnkemKvo6H
Privkey: 5J48B7JDChgvAUGPA5p6yvjwZtyFufJizc6jFSci6Jwu9KzQdFh

Only CPU though, and no bc1-address. Using non-native SegWit feels a bit like a 50% solution. It's multisig, not segwit. See Thirdspace's post.

Two weeks ago, I sent some coins to the generated P2SH address without knowing about how to access it. I just recently found out a way. I am not a technical guy so please always check if you have an access to the address generated before sending coins.

It's all still new to me too. I'll experiment more later.

You cannot merit that post

Loaded it back again. Mistakenly pressed delete.

Yeah. Wondering about the same.



[P2SH address generation- Vanitygen]

Code:

-F script

The command generates a P2SH address , a P2PKH address and a Private key. Command was first posted by someone here:  https://github.com/exploitagency/vanitygen-plus/issues/30


How to generate Redeem script?

[1] Copy the private key and go to bitaddress.org . Go to Wallet details and paste that private key you copied. Check for the public key (uncompressed) and copy it.

[2] Go to https://coinb.in/multisig/ . Click New >> Multi-Sig Address . Click the "-" sign against the uncompressed public key input field until you have only one field to enter your uncompressed public key. Paste your public key that you copied into that only field for entering uncompressed private key. Change the amount of signatures required to release the coins to "1" and click "Submit". It will generate your Redeem script for the P2SH address that you generated.


Rest regarding spending your inputs , I would suggest going through mocacinno guide: http://www.mocacinno.com/blog/create-sign-broadcast-transactions-using-coinb/

[Don't know if its been brought up earlier. Apologies if there is topic already available regarding this ]

This is not "non-native SegWit" address, is it?
This is just a standard non-segwit P2SH address, right? (non-segwit multi-signature address)
Since this is not a segwit P2SH-P2WPKH address, then it won't save us on tx size and fee

"The command generates a P2SH address , a P2PKH address and a Private key."
and your instruction to generate its redeem script confirms that this is a multisig address
when you spend your coin, how is the transaction like? as small as segwit or double just like multisig address?
any benefit using this kind of P2SH 3xxx address compared to legacy compressed address?

[Avirunes]

-snip-

Yes the address it generates is a non-segwit one. There is no benefit like segwit ones.

Some users of  vanitygen knows about the command but don't know instructions to access the generated address. That is why I have posted this in order to help them with instructions on accessing it.

I think you're right. That does fit Avirunes' multisig redeem script better.
(I really can't remember names like "P2SH-P2WPKH" and the different versions)

I'll edit my post.

i have an old laptop   its saying it will take 50 days to generate the address.. is this normal.. and will it harm my computer?

Depends. If you are trying to generate a vanity address with many characters and/or case-sensitive, the difficulty will be higher and it's obvious going to take a while. But keep in mind that this is
an estimate.

A laptop doing this type of key generation can be damaging to it's components as it also generates a lot of heat and laptops are typically not equipped to handle the heat dissipation.

Are there any trusted vanityget forks that are worth checking? An increase in performance would be ideal.

Speaking of performance, have you tried using Oclvanitygen instead?
With a single GTX** GPU, you can generate a customized first 5-character address in less than 10 minutes, that's "fast" as long as you have the sufficient hardware.

Example: My address 1two34E2WcKXUNqnjSLKnc8fvmCST1iuW (two34 prefix) was made in just 6 minutes.
Not bragging since it's quite slower than others' but with this, vanitygen (Oclvanitygen) might be the fastest (standard address) generator available.

[exander77]

Any new developments on any projects like this like with regex on GPU?

I get 100mkey on a 1080ti if anyone wanted to know

I have  animplementation of what I call conditions, it is not exactly a regexp, but may be even more useful, I can target each character indexing it either from left (0,1,2,...) or right (-1,-2,-3,...).

[position][exact|range|lower|upper|number|letter|lower&number|upper&number][value1][value2]...

Where position is from 0...n from the start of the address and -1, -2...-n from the end of the address.

I can also code arbitrary function for special cases.

The speed is probably the half of standard oclvanitygen (130Mh/s vs 60Mh/s on my Vega Frontier Edition Liquid), meaning much faster than on CPU.

can someone point me to a good source on standard format of P2SH segwit address?
I can't seem to generate/find address with starting pattern '3r'
I'm trying to figure out if there's certain limitations on the possible generated address
the allowed characters still the same, right? no 0 (zero), O (uppercase o), I (uppercase  i) and l (lowercase  l)
"123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"
is there certain impossible sequence of characters (pattern) that can be generated?

3r is out of range, 3N is the highest possible prefix, 123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz.

It is not about impossible sequence, address is a number in some range which is encoded using using Base58 coding.

Code:

./vanitygen -F script -C BTC 3r
Generating BTC Address
Prefix '3r' not possible

[Thirdspace]

3r is out of range, 3N is the highest possible prefix, 123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz.

It is not about impossible sequence, address is a number in some range which is encoded using using Base58 coding.

that's what I meant, prefix! so it's out of range = prefix 3r doesn't exist
but prefix '33r' would still be possible, right? so I still can try to find address starts with '33rds'
I think it won't take long to find such address, would be unbelievably lucky if it gives me '33rdspace'

33r is not a problem, if you compare those prefixes it goes like this: 33r < 3N < 3r
So 33r is the lowest of those three, 3r is the highest.

I have a system with 2 CPUs. As the applet uses the CPU, the original bitcoinind + patch vanity uses both CPUs, but vanitygen seems to only use one.
