Is there a way to protect more the wallet except the passphrase ? the passphrase is nice but what about keyloggers or others bad things
Keyloggers and potential viruses on your computer, are not in our hands. It's up to you to make sure you practice safe habits while on the web, and properly secure your systems and do a scan regularly for anything malicious. Be sure to write down a physical copy as well in case you lose it on a computer.
1) come up with your phrase
2) make a MD5 hash tag at

4) no worries about a hidden keystroke logger.
I should also create a website which calculates md5s. I would get many new password hints...
