eth addresses question

[douglasdeodato]

Hi, how I can make sure the addresses generated in my local-machine will be unique?

I mean if someone install this app in other machine, he will be able to get kinda the same address?

I am planing to use this with a website so the addresses will be unique for the users, understand my question?

thank you.

You are no more likely to get a conflicting address using this, than someone generating random addresses and trying to find your balance. If there was a way to generate specific addresses private keys we'd be in a world of trouble.

I have not looked at the code but I can only assume this tool is generating random addresses and checking to see if the first x matches. Depending on the length of your desired vanity prefix it becomes exponentially harder to expect to see an address with that prefix. Therefor this is no more dangerous than a random address generator checking for balance on a list of addresses.
