I was looking at bitaddress.org 's brain wallet feature. It takes in a passphrase and generates a private key/public address.
Could the same algorithm be used to create a whole series. If the passphrase as "Bla Bla" could you make the seed to create the next address "Bla Bla1" and then do "Bla Bla2".... to create an infinite series of addresses?
Is there any flaw that anyone sees in using the algorithm in bitaddress to do this (if not I might submit a patch to add this feature).
Does Armory use the same passphrase->seed algorithm that bitaddress does (are they compatible)? Is there a reason?
Also, has anyone figured out a method to take some seed that can just generate public addresses on an exposed merchant server that would have a private seed on a secure machine that could generate the corresponding private keys? Does anyone have any code in any language to do this?
