Add comments to `refreshed` method variable in wallet2
Implements view tags as proposed by @UkoeHB in MRL issue
https://github.com/monero-project/research-lab/issues/73
At tx construction, the sender adds a 1-byte view tag to each
output. The view tag is derived from the sender-receiver
shared secret. When scanning for outputs, the receiver can
check the view tag for a match, in order to reduce scanning
time. When the view tag does not match, the wallet avoids the
more expensive EC operations when deriving the output public
key using the shared secret.
- Try empty passphrase first when opening a wallet, as all Trezors will have passphrase enabled by default by Trezor Suite by default.
This feature enables easier access to all users using disabled passphrase (or empty passhprase)
- If wallet address differs from device address with empty passphrase, another opening attempt is made, without passphrase suppression,
so user can enter his passhprase if using some. In this scenario, nothing changes to user, wallet opening just consumes one more call
to Trezor (get wallet address with empty passphrase)
- also change how m_passphrase is used. Previous version did not work well with recent passphrase entry mechanism change (made in Trezor),
thus this commit fixes the behaviour).
There are quite a few variables in the code that are no longer
(or perhaps never were) in use. These were discovered by enabling
compiler warnings for unused variables and cleaning them up.
In most cases where the unused variables were the result
of a function call the call was left but the variable
assignment removed, unless it was obvious that it was
a simple getter with no side effects.
- choice where to enter passphrase is now made on the host
- use wipeable string in the comm stack
- wipe passphrase memory
- protocol optimizations, prepare for new firmware version
- minor fixes and improvements
- tests fixes, HF12 support
