I am fairly new to Ripple and I did a lot of reading yesterday. I can't remember if I read the post here or at xrpchat or somewhere else but the post was fairly detailed about how ripple passcodes and wallet addresses are generated. I believe this may have been followed by an explanation of how long it would take to "guess" correctly the passcode associated with a particular address. I've tried searching but not having much luck. Anyone know what I'm talking about?
