For the 'fullyEncrypted' option we now simply fully
encrypt the entire blob of both the secrets file as well
as the wallet.dat (which transactions we own).
We encrypt using a standard AES256 encryption scheme.
The key is 256 bits and we derive that from a user provided password
which we double-hash (sha256). Additionally we use a randomly generated
salt for a specific wallet that is fed into the hashing algo as well.
This version simply encrypts the private keys of a wallet, which makes
it quite basic. A good start.
When the wallet contains fused transactions we select UTXOs a bit
different in order to maximize privacy.
Additionally this prefers an UTXO that is closest in value to the paid
amount.
To avoid recompiles and such generally to simplify stuff, this
moves all the code into a static lib that is then linked with
by the various apps (including tests).
As transactions are found on the blockchain we remember the signature
type used in order to avoid one private key to be used for both types of
signatures, which can cause compromised keys.
This changes the default generated wallet to be a HD wallet.
We also add a helper class to configure newly created wallets from QML.
This finishes up the new wallet panel to have all the visible features
actually do something.
For each transaction allow to click on it and show lots of further
details about it.
This also fixes various bugs and adds some basic helper methods in
various places.
The QML is barely functional, getting the right data exposed was the
only goal today.
When a transaction is received by the p2pnet layer via a simple INV/
GetData we now process this and properly lock the outputs it spent to
avoid creating double spending transactions.
One task is left: properly recognize when a mined transaction
invalidates another transaction (like an unconfirmed one) and update the
datastructures.
The code to re-org all transactions in a block so transactions that
depend on others are processed after those they depend on had a silly
bug (missing line), fixed that but also made it unit-testable to
demonstrate the bug.
