From a1fd1d499c6a967d2cd011c57eb79f6ebc5847f4 Mon Sep 17 00:00:00 2001 From: Dusan Klinec Date: Sat, 23 Feb 2019 15:28:18 +0100 Subject: device/trezor: HF10 support added, wallet::API - import only key images generated by cold signing process - wallet_api: trezor methods added - wallet: button request code added - const added to methods - wallet2::get_tx_key_device() tries to decrypt stored tx private keys using the device. - simplewallet supports get_tx_key and get_tx_proof on hw device using the get_tx_key feature - live refresh enables refresh with trezor i.e. computing key images on the fly. More convenient and efficient for users. - device: has_ki_live_refresh added - a thread is watching whether live refresh is being computed, if not for 30 seconds, it terminates the live refresh process - switches Trezor state --- src/device/device.hpp | 21 ++++++++-- src/device/device_cold.hpp | 96 ++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 113 insertions(+), 4 deletions(-) (limited to 'src/device') diff --git a/src/device/device.hpp b/src/device/device.hpp index 408f64c8b..471302bc4 100644 --- a/src/device/device.hpp +++ b/src/device/device.hpp @@ -70,6 +70,7 @@ namespace cryptonote struct account_keys;
