There are a multitude of programs for generating vanity addresses but you should definitely do your research on how they work and their authors before you use them.

What could go wrong for example?

If the program creates a private key, uses a hash to find the public key and make a mistake. It could potentially give you a public key and the incorrect private key.

Is there another way to create addresses programatically?

I am having a hell of a time trying to get vanitygen to work on RedHat. I just need to be able to produce addresses with private keys offline.

As it's just standard python, this should work under Linux as well and is extremely short to review:

Sounds like you may be interesting in the sx command line utilities

Someone writes a program that creates a public and private key for you, but is easily replicated. All they have to do is run their program to obtain your public key and they then have your private key.

Or something to that affect.

Have you seen my python script built from the electrum codebase?

https://bitcointalksearch.org/topic/electrum-seed-recovery-stand-alone-python-script-612143

(just make sure to get a new random seed, dont use the default!)

Thanks for the info. I'll check it out.

I know people use vanity generators for addresses like it's no big deal to make millions of addresses,
But at some point if BTC gets mass adored wouldn't we run out of addresses?

Trust me, the sheer keyspace is far larger than that.

Quote

Generating an address doesn't touch the network at all. You'd only be wasting your CPU resources and disk space.

Also, a collision is highly unlikely.

Keys are 256 bit in length and are hashed in a 160 bit address.(2^160th power) Divide it by the world population and you have about 215,000,000,000,000,000,000,000,000,000,000,000,000 addresses per capita.

@OP: I would advise oclvanitygen (try the updated lifeboat one) rather than just pure vanitygen as GPUs will work more efficiently at finding addresses than CPUs.

I sure hope it gets mass adored.

Well I thought there was a more clever way, but bruteforce it is.

Vanitygen actually avoids redoing expensive calculations over and over again (mainly doing additions as I understand it). So it is a little clever.

These are the vanity addresses that the people make using the brute force. it requires some kind of software and generation of these addresses takes time.

Well I thought there was a more clever way, but bruteforce it is.

if there was a more clever way it wouldn't be very well encrypted.

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

Note that address re-use has severe privacy implication.

I have been using single-use vanity addresses myself.

Edit: Real life example of somebody regretting vanity addresses.
