Hi Guys,
I am not sure if this has already been discussed, or slated for implementation, if so please forgive my redundant post.
I have an idea about how we can secure wallet.dat somewhat against theft (ie. copy of the file).
Why not implement AES encryption of the private keys stored in there?
(no point protecting public keys, as balance information is public anyway)
a) Everytime a new ID is generated and everytime someone wants to send a transaction, why not have the client ask for a password to encrypt/decrypt the private key as appropriate?
b) During encryption/decryption, the supplied password is hashed and then the hash is used to encrypt/decrypt.
c) This way even if the wallet is stolen, no one can spend any of your money (which is the most important thing) which should discourage wallet.dat theft.
d) Furthermore, in the software it would be a good idea to make sure that once the id generation/send transaction process completes, all traces in memory of the unencrypted private key, password and password hash are zeroed out.
What do you guys think about this?
I think such a feature will help with mass adoption, because it would say to the average user, you can copy my wallet all you want, but you can't spend anything in it.
