I may write code in exchange for bitcoins.

Hashes are impossible by hand...
Wouldn't a LiveCD on an offline HDD-less PC enough?

I haven't looked at the details of the hashing algorithm used to generate the public address from the private key. However, I don't think impossible is correct. I mean, everything a computer does can (in principle) be simulated using a very long tape and a pencil (see universal Turing machine).

Im just saying, difficult/tedious != impossible.

I've wondered if this was possible myself...even if you could use a calculator

Well I imagine that creating the raw private key in hex format wouldn't be exceedingly difficult, but deriving the bitcoin address from the private key would be because there is hashing involved.

Not sure this really belongs here, but I did not know where else to post it.

How difficult would it be to create a formula that allows one to create a private and public key using just paper and a pencil?

To me this would be the most secure possible method for making a wallet, as the private key will never have existed on a computer, even one thats offline.

Of course one would also need a hardware random number generator, but that can be easily done. (Using dice, a falling pen, ect.)

I know the math has to be pretty extreme, so its just a thought.
