I'm using the MultiBit client to manage my wallet (right here on my computer), but I am concerned about the security with regards to the
*-backup folders that it creates automatically.
When I inspect the
wallet-unenc-backup directory, I find 2 pairs of
.wallet.cipher files. Using a text editor, I can see that the
.info file only contains my public bitcoin address and a line referring to the
rolling-backup directory and some other numbers. The
.wallet.cipher file shows weird characters.
.wallet.cipher file contain a private key unencrypted? If so, why does the client not warn me about this? Is it because its users are expected to know this, or am I wrong about this?
The other folders contain
.info files as well, and
.wallet files (probably and encrypted wallet).
Any clarification on the actual information stored in these files and whether that information is encrypted would be helpful.
I did read the documentation of MultiBit, but their description of these files, found here, isn't very clear and doesn't contain warnings where I expect them to be.
I have put a password on my wallet using the "file" menu in MultiBit.
