hi, there.
I dumped my private key with the Protoshares client, then pasted it to the bitaddress.org to show other formats of it. But it says,
"The text you entered is not a valid Private Key!"
so, pts privkey is not valid bitcoin priv key? cuz I know SHA-256 of a file can be used as a form of bitcoin priv key.
If so, can't I use the same way to generate my complicated brain wallet? Or is there some other similar ways to do this?
Thank U.
