Google is your friend steelboy (or DuckDuckGo if google is not your friend) ... https://en.bitcoin.it/wiki/Vanitygen answers both your questions (yes and yes, plus the speeds) and provides links. Good luck, and be careful with those private keys, they are generated in plaintext so be sure your Mac is clean, and you'll need to import them into a wallet before you can use them. |

I did check that page but it's pretty complicated. I went to the github page and downloaded the zip file. The folder is full of files with crazy extensions. Very confused. |

a 7-letter word after 1 (e.g. 12345678) you can get mined for you fairly cheaply.
8 is more difficult/expensive, and the current record is 9.
3 or 4 letter words you can get yourself on your laptop's cpu in a matter
of minutes (4) or seconds (3) after reading the "vanitygen" thread on the forums.

There is no difference between using a paper wallet and a vanitygen address. In both cases you have a private key and the associated bitcoin address (if you print out your vanity address and private key, then you have created a paper wallet). The vanity address creation services work rather differently from vanitygen as they employ a split-key, and as I'm not an expert on this (though I am curious about how it works, so I'll be taking a look at it), I'll just refer you to the support thread https://bitcointalk.org/index.php?topic=84569.0 |

Bitcoin is the ultimate freedom test. It tells you who is giving lip service and who genuinely believes in it.
... ... In the future, books that summarize the history of money will have a line that says, “and then came bitcoin.” It is the economic singularity. And we are living in it now. - Ryan Dickherber... ... ATTENTION BFL MINING NEWBS: Just got your Jalapenos in? Wondering how to get the most value for the least hassle? Give BitMinter a try! It's a smaller pool with a fair & low-fee payment method, lots of statistical feedback, and it's easier than EasyMiner! (Yes, we want your hashing power, but seriously, it IS the easiest pool to use! Sign up in seconds to try it!)... ... The idea that deflation causes hoarding (to any problematic degree) is a lie used to justify theft of value from your savings.

I would highly not recommend you use firstbitsrepo due to the ease of making a vanity address, especially those under 8 characters. My computer can generate any 7 character word in approx 2 hours. And about 5 days for any 8 character word. As for a 9, on the other hand, about 160 days. I -really- don't want to knock him or anything, it's a honest service, but it's extremely overpriced. For example he has 1Acid vanity address for sale for 20$. Here's an example of how fast I can make a 1Acid address: http://www.gad.me/ss/20130806161938475.png I literately clicked start and that's how many I had in a matter of seconds... Could make about 10k addresses or more an hour if I use both cards... But honestly, his 8 character and 9 character prices are much more realistic. It would, in fact, take a very long time to find a 9 character address looking for one specific word. |

Regarding the split key generation. Is that completely safe? It all looks good but I want to be sure that it's 100% before going for it |

And if you have any kind of GPU, you could make your own address under 7 characters fairly quick. |

Afraid I don't have a gpu. Just a regular old laptop.
I've seen a couple of sites offering split key services. Anybody used any of them and can vouch for them?

Tell me how to do the split key process and I'll make you one real quick  . I'm familiar with the vanity gen, but not split key process. |

I did myself a quick test following the instructions on https://bitcointalk.org/index.php?topic=84569.0An example (available from gobittest website):
We have a private key:
18E14A7B6A307F426A94F8114701E7C8E774E7F9A47E2C2035DB29A206321725
which maps to public key:
0450863AD64A87AE8A2FE83C1AF1A8403CB53F53E486D8511DAD8A04887E5B23522CD470243453A 299FA9E77237716103ABC11A1DF38855ED6F2EE187E9C582BA6
and say we want to find a pattern "166". One of the solutions takes a form of a private key
B18427B169E86DE681A1A62588E1D02AE4A7E83C1B413849989A76282A7B562F
mapping to public key:
049C95E0949E397FACCECF0FE8EAD247E6FD082717E4A4A876049FB34A9ADED110DFEA2EF691CC4 A1410498F4C312F3A94318CD5B6F0E8E92051064876751C8404
If we add the two public keys (like the person looking for the solution would do), we get a public key:
0436970CE32E14DC06AC50217CDCF53E628B32810707080D6848D9C8D4BE9FE461E100E705CCA98 54436A1283210CCEFBB6B16CB9A86B009488922A8F302A27487
which is equivalent to this address:
166ev9JXn2rFqiPSQAwM7qJYpNL1JrNf3h
If we add the two private keys (like the person requesting the address would), we get:
CA65722CD418ED28EC369E36CFE3B7F3CC1CD035BFBF6469CE759FCA30AD6D54
which maps to the same public key as the sum of the public keys, and thus - to the same address
I tested it ...
# vanitygen.exe -P 0450863AD64A87AE8A2FE83C1AF1A8403CB53F53E486D8511DAD8A04887E5B23522CD470243453A299FA9E77237716103ABC11A1DF38855ED6F2EE187E9C582BA6 1Am

PrivkeyPart: 5JC5PMGVL9PkgLoWh4VJDHZTEgpZr8sAv2KwHG8uxjvLskKiZDt
Now use keyconv to combine, BUT it needs WIF not hex, so first convert using my script (or use https://bitaddress.org)
# python bitaddr_hexprompt.py
Enter hex: 18E14A7B6A307F426A94F8114701E7C8E774E7F9A47E2C2035DB29A206321725

IT WORKS!!
So if you wanted to do it, you need to have vanitygen installed on your computer (download the binaries, not the git if you're on windows)
First generate your private key in WIF format (I'm using keyconv here, but any other method will work).
# keyconv -G
Pubkey (hex): 04069f08dd2b573cdf7b647236f11ba8c6020e83dae50d37cdeec3a63a4d0c092a3f20873cfbd6212754b763f9e477b14ea729db0176d80fa43f4beec9bd2024a5
Privkey (hex): 621B77463A634509FFA0C8582E3909D00FC2076389AE9318848EED1A91AF0B58

Privkey: 5JZVbnRV1gYky2rJ38RcpYVz74MewDRoH2m1a1JmDEBkAffePU6
Then you send gadman2 a PM with the public key ...
04069f08dd2b573cdf7b647236f11ba8c6020e83dae50d37cdeec3a63a4d0c092a3f20873cfbd6212754b763f9e477b14ea729db0176d80fa43f4beec9bd2024a5
gadman2 does ...
oclvanitygen -P 04069f08dd2b573cdf7b647236f11ba8c6020e83dae50d37cdeec3a63a4d0c092a3f20873cfbd6212754b763f9e477b14ea729db0176d80fa43f4beec9bd2024a5 1xxxxxxxx
Which might come up with something like ...
# vanitygen -P 04069f08dd2b573cdf7b647236f11ba8c6020e83dae50d37cdeec3a63a4d0c092a3f20873cfbd6212754b763f9e477b14ea729db0176d80fa43f4beec9bd2024a5 1x

PrivkeyPart: 5Jo6gDpEbEhbZRu5RbUqq16DcPr2E6EZGPNQyBDP1cWFYMR4qh3
He sends you the PrivkeyPart: 5Jo6gDpEbEhbZRu5RbUqq16DcPr2E6EZGPNQyBDP1cWFYMR4qh3
And finally you combine with
# keyconv -c 5JZVbnRV1gYky2rJ38RcpYVz74MewDRoH2m1a1JmDEBkAffePU6 5Jo6gDpEbEhbZRu5RbUqq16DcPr2E6EZGPNQyBDP1cWFYMR4qh3
Address: 1x4nfoivXG8UBjUzUkWtyPJDJ5cKBsjct
Privkey: 5KYJhKndXTgNGTN6RXTZZVr5VrNkxAoGpc4eK1UPyxqMYHyAzs5
And that's your private key and vanity address. Import it into a wallet and check that the address matches (or you can do this with https://bitaddress.org wallet details tab, which you can also download from github for offline use). Test it out with something simple first before going all the way. PS I hope I've got that right, just learning about it myself. |

Then you send gadman2 a PM with the public key ...
04069f08dd2b573cdf7b647236f11ba8c6020e83dae50d37cdeec3a63a4d0c092a3f20873cfbd6212754b763f9e477b14ea729db0176d80fa43f4beec9bd2024a5
gadman2 does ...
oclvanitygen -P 04069f08dd2b573cdf7b647236f11ba8c6020e83dae50d37cdeec3a63a4d0c092a3f20873cfbd6212754b763f9e477b14ea729db0176d80fa43f4beec9bd2024a5 1xxxxxxxx
Which might come up with something like ...
# vanitygen -P 04069f08dd2b573cdf7b647236f11ba8c6020e83dae50d37cdeec3a63a4d0c092a3f20873cfbd6212754b763f9e477b14ea729db0176d80fa43f4beec9bd2024a5 1x

He sends you the PrivkeyPart: 5Jo6gDpEbEhbZRu5RbUqq16DcPr2E6EZGPNQyBDP1cWFYMR4qh3
And finally you combine with
# keyconv -c 5JZVbnRV1gYky2rJ38RcpYVz74MewDRoH2m1a1JmDEBkAffePU6 5Jo6gDpEbEhbZRu5RbUqq16DcPr2E6EZGPNQyBDP1cWFYMR4qh3

And that's your private key and vanity address. Import it into a wallet and check that the address matches (or you can do this with https://bitaddress.org wallet details tab, which you can also download from github for offline use). Test it out with something simple first before going all the way. PS I hope I've got that right, just learning about it myself. Thing is that block I the middle of your response, with all the code, is like Latin to me. I literally have no idea what that means or how to interpret that. |
