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.

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. 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.

"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?

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.

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.

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.

Donate is appreciated, but nobody yet donated.

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.

./vanitygen -F script -C BTC 3r

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' Grin

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.

I`m trying to run oclvanitygen with my GPU. It`s a RX480. I get this when I run it: https://imgur.com/a/LWDigth
My OS is Win10 64 bit. I use the following config: .\oclvanitygen.exe -D 0:0 -o results.txt 1test
Any ideas? I should add that this card worked with oclvanitygen before but I dont remember if I had different drivers back then.

I quite often get the following "out of resources" error when running oclvanitygen, sometimes after a few minutes and sometimes after several hours (nothing else is running at the time).  Is there a way to reduce the load on the GPU (similar how you can reduce the number of cores on the CPU version)?  Or anyone know how I might fix this?  What does "grid" do, btw?  Thanks

If the "resources" that you're running out of is GPU memory, you can set the number of threads to use:
Code:
./oclvanitygen -t 32
When I test on my Nvidia GPU, it does use less memory, and the number of keys/s goes down. What's weird though, is that even my mouse lags when I run oclvanitygen with limited threads.
Either way, it may be worth trying.

Hi, I have problems to compile it on Ubuntu 18.04
I used make but there are several compiling errors.
I already installed those dependencies https://github.com/samr7/vanitygen/wiki/Installation
On Ubuntu libpcre-dev is not availible so I used libpcre3-dev

I had funds stolen from a 2011 address that I think was generated with vanity gen.
The address is 192SGgMXpzpjKyt4mnoNaAksvpA4y2HAKS and since the private key has been leaked I might as well post it here.

5JfsVwQKYbRDbjcyvX4j8p47Kmp8QUBw4mvxuxcV41sqKyKH5PK

Is there anybody that do analysis on the key or something? I am trying to figure out how it was compromised. Did my OS got hacked? My other funds where not stolen.
Did I  generate it with a compromised version of vanitygen that leaked the keys or generated weaks key on purpose?

Any help is appreciated.
