Thanks, I try. Taking lengthy breaks helps a lot.


When someone understands something exceptionally well they are able to explain it in the simplest terms.

I think laptops are very common among posters here. Their CPUs tend to be weak and they often come with a GPU that isnt capable of OpenCL caluclations.

@shorena,

I honestly don't know how you've survived on this forum for so long. You have the patience of a saint.

It seems that there are a lot of people, who fail at basic logic, mathematics and reading and comprehension, who have somehow stumbled into the world of Bitcoins.

I'm not sure if it is the media stories talking about people making fantastic amounts of money because Bitcoin went from being near worthless to being ~USD$650... but there are a lot of people around who just don't seem to understand the core concepts.

Granted, the world of crypto can be very confusing, and public keys, private keys, hashes and all the associated math and interrelationships can be a bit overwhelming... but still... a little bit of reading is enough to grasp the fundamentals, which (tricky crypto math aside) isn't really that hard to understand.

Split key generation is perfectly safe... at least as safe as Bitcoin itself. I assume that poster was getting confused with so-called vanitygen websites that don't do split key and just spit out a pub/priv key pair and "promise" not to record the private key...  

Also... why people don't just download the vanitygen app themselves and run it is beyond me?? It's tiny, and even on a single AMD R9-270 card I can generate relatively simple 4 or 5 char vanity addresses in minutes...

Split key vanitygen is not a lie its ECDSA math. Person A creates one private key (A) and sends the public key (A_pub) to person B. That person now searches for a private key B. It must be in a way that its public key B_pub combined with A_pub results in a bitcoin address with the wanted prefix (e.g. 1test). A combines the keys A and B for the final private key C that has an address with prefix 1test. The key B alone is not enough to get C. You need both.

A very simplistic way to understand this is to think about clocks. Lets say I think of a time (I wont tell you) and you tell me a time (13:37). I now add both times and create a new time (mod 24 and 60). Which time is it?

This holds even true for basic addition: A(unknown) + B (known) = C (unknown). If you can tell me a way to know C for a given but unknown A. I will stop my vanity gen business and send all my income to an address of your choosing.

If it's acceptable to use the current vanitygen command line with one output file and split that file afterwards in the 2 files you want, this would beich easier to achieve and you can find very easily somebody to help you out with the (after)splitting.

And it should be much safer too...

if iam create custome addres bitcoin with vanity genartor
and must send private key is next my addres save or not
because private key send my balance bitcoin can lost with hand private key

No never get lured by any vanity address generator as whatever they claim about not saving your private key or creating two seperate file by two different personal is just a lie. In creating vanity address private key is also generated and there will be no proof they can provide that they haven't saved your private key with them.

Better u try but i haven't tried this but this sound quite safe and you can do it by yourself if you have bitcoin client installed already and completely sync.

in fact for what we modify our wallets address if could a risk losing balance because the owner knows your private key.

¯\_(ツ)_/¯

Might be an A B problem, where OP has problem A and thinks B is the solution, so they ask for help with B instead of help with A (which they actually want to solve).

Failing that... editing the pattern.c source file from the vanitygen github and recompiling should enable one to output the values to 2 separate files instead of either the console or to 1 file. (Hint: around line 500 is the vg_output_match_console() procedure that deals with outputting the matched addresses/keys)

I'm just trying to figure out why someone would want something like this in the first place?  

Sounds more like something one would do with a little linux command line fu. Im thinking with awk, grep and pipes it shoudl be possible to take the output from vanitygen and pipe it into two different files.

I don't know if this can help but look at this service that shorena is providing here: https://bitcointalksearch.org/topic/bitcoin-vanity-addresses-1257817
Maybe you can ask him/her where to find a software that you are looking for since he/she knows a thing about vanity address.

I have never seen a software like this . but what is the point from making each of the public and private kkeys in separated files? After generating the addresses normally with vanity gen you can do whatever you want , organize them or separate them

What is wrong with using the vanitygen commandline app? Why do you specifically need the address and the private key separated into 2 separate files?

Is there some special use-case that you have in mind with regards to security or something?
