The wallet and the daemon applied different height considerations
when selecting outputs to use. This can leak information on which
input in a ring signature is the real one.
Found and originally fixed by smooth on Aeon.
f197599 wallet: encrypt the cache file (moneromooo-monero)
98c76a3 chacha8: add a key generation variant that take a pointer and size (moneromooo-monero)
It contains private data, such as a record of transactions.
The key is derived from the view and spend secret keys.
The encryption currently is one shot, so may require a lot of
memory for large wallet caches.
This obsoletes the need for a lengthy blockchain rescan when
a transaction doesn't end up in the chain after being accepted
by the daemon, or any other reason why the wallet's idea of
spent and unspent outputs gets out of sync from the blockchain's.
Pros:
- smaller on the blockchain
- shorter integrated addresses
Cons:
- less sparseness
- less ability to embed actual information
The boolean argument to encrypt payment ids is now gone from the
RPC calls, since the decision is made based on the length of the
payment id passed.
A payment ID may be encrypted using the tx secret key and the
receiver's public view key. The receiver can decrypt it with
the tx public key and the receiver's secret view key.
Using integrated addresses now cause the payment IDs to be
encrypted. Payment IDs used manually are not encrypted by default,
but can be encrypted using the new 'encrypt_payment_id' field
in the transfer and transfer_split RPC calls. It is not possible
to use an encrypted payment ID by specifying a manual simplewallet
transfer/transfer_new command, though this is just a limitation
due to input parsing.
It should avoid a lot of the issues sending more than half the
wallet's contents due to change.
Actual output selection is still random. Changing this would
improve the matching of transaction amounts to output sizes,
but may have non obvious effects on blockchain analysis.
Mapped to the new transfer_new command in simplewallet, and
transfer uses the existing algorithm.
To use in RPC, add "new_algorithm: true" in the transfer_split
JSON command. It is not used in the transfer command.
dc4dbc1 simplewallet: allow creating a wallet from a public address and view secret key (moneromooo-monero)
6a0f61d account: allow creating an account from a public address and view secret key (moneromooo-monero)
e05a58a wallet2: fix write_watch_only_wallet comment description (moneromooo-monero)
4bf6f0d simplewallet: forbid seed commands for watch only wallets (moneromooo-monero)
The new save_watch_only saves a copy of the keys file without the
spend key. It can then be given away to be used as a normal keys
file, but with no spend ability.
Sends all the dust to your own wallet. May fail (if the fee required
is more than the dust total). May end up paying most of the dust in fees.
Unlocked dust total is now also displayed in "balance".
Based on tewinget's update.
Make OpenAlias address format independent of existing DNS functions.
Add tests.
Test:
make debug-test
cd build/debug/tests/unit_tests
# test that regular DNS functions work, including IPv4 lookups.
# also test function that converts OpenAlias address format
make && ./unit_tests --gtest_filter=DNSResolver*
# test that OpenAlias addresses like donate@getmonero.org work from
# wallet tools
make && ./unit_tests --gtest_filter=AddressFromURL.Success
Daemon interactive mode is now working again.
RPC mapped calls in daemon and wallet have both had connection_context
removed as an argument as that argument was not being used anywhere.
simplewallet run without a wallet path argument should prompt again if
an invalid path was entered.
Validity here currently means the string isn't empty.
Allow pre-JSON wallet format to load without depending on existing bin
file.
Don't write bin file while inside keys rewrite, so bin file write
behavior here matches that of regular wallet load.
Fix for simplewallet loading a wallet with a keys file but no bin file.
- this situation previously required a user to restart simplewallet
before it would refresh its blockchain from the server.

wallet2::store_keys() and wallet2::load_keys() should only use the JSON
attribute "seed_language" when applicable. That is only for
deterministic wallets.
- store_keys() don't add JSON attribute "seed_language" if
seed_language is empty
- load_keys() don't call set_seed_language if JSON attribute
"seed_language" not present
