I am a new adopter of Bitcoins, forgive the ignorance. (note these are test transactions)
I am using the Bitcoin qt client and I am very confused and think I have done something wrong.
I have two computers A and B both with Bitcoin qt client on. I have made wallets on both computers.
After launching Bitcoin qt client for the first time on computer A I created two addresses using the 'new address' button. I then clicked 'Encrypt Wallet' and entered a passcode. Note I only did this process once, even though I created two addresses.
I then transfered two test transactions to the wallet on computer A from Bitstamp. These came through as:
(don't know if anything looks wrong in that picture?)
I then tried my first ever test transaction and sent it to the address I created on computer B (I have never encrypted this wallet).
To my surprise this sent, even though I didn't have to enter any kind of passcode on computer A? Plus my address on computer B isn't even encrypted?
Does that mean anyone can use the funds I have in my wallet on computer A, without my passcode?
The status of the transaction on computer B is also, 8 confirmations? Is this a sign of a mistake. Also the 'from' is marked as unknown - is this important?
There is also no lock icon on my QT client, which I have been told there should be if the wallet has been encrypted?
I'm confused, please advise. Sorry for my ignorance, I am not a technically minded person but trying to adopt bit coins.
