in bitadress.org in brain wallet when i type passphrase "satoshi nakamoto" it generates privatekey different than what a normal sha256 online calculator generates. Why sha 256 of bitaddress gives different private key than a normal sha256..
below is example


private keys generated by both for same phrase i
BTCs different
WHY??Everyone's talking about bitadress. I don't think it's safe. Then tell me where can we get the most reliable BTC wallet?
