This is performed by saving the SHA512(salt+passphrase) of the waddrmgr.Manager private passphrase each time the manager is unlocked. If another call to Unlock is performed before the next Lock, the hash is applied to the new input. If it matches, we know the passphrase is (likely) equal, so return early and continue using the crypto keys already in memory. If it does not match, we know for certain the passphrase is incorrect and the manager is locked. |

(https://travis-ci.org/btcsuite/btcwallet)
btcwallet is a daemon handling bitcoin wallet functionality for a single user. It acts as both an RPC client to btcd and an RPC server for wallet clients and legacy RPC applications.
The wallet file format is based on Armory and provides a deterministic wallet where all future generated private keys can be recovered from a previous wallet backup. Unencrypted wallets are unsupported and are never written to disk. This design decision has the consequence of generating new wallets on the fly impossible: a client is required to provide a wallet encryption passphrase.
btcwallet is not an SPV client and requires connecting to a local or remote btcd instance for asynchronous blockchain queries and notifications over websockets. Full btcd installation instructions can be found here.
As a daemon, btcwallet provides no user interface and an additional graphical or command line client is required for normal, personal wallet usage. Conformal has written btcgui as a graphical client to btcwallet.
This project is currently under active development is not production ready yet. Support for creating and using wallets the main Bitcoin network is currently disabled by default.
Installation
Windows - MSI Available
Install the btcd suite MSI here:
https://opensource.conformal.com/packages/windows/btcdsuite/
Linux/BSD/POSIX - Build from Source
-
Install Go according to the installation instructions here: http://golang.org/doc/install
-
Run the following commands to obtain and install btcwallet and all dependencies:
$ go get -u -v github.com/btcsuite/btcd/...
$ go get -u -v github.com/btcsuite/btcwallet/...
- btcd and btcwallet will now be installed in either
$GOROOT/binor$GOPATH/bindepending on your configuration. If you did not already add to your system path during the installation, we recommend you do so now.
Updating
Windows
Install a newer btcd suite MSI here:
https://opensource.conformal.com/packages/windows/btcdsuite/
Linux/BSD/POSIX - Build from Source
- Run the following commands to update btcwallet, all dependencies, and install it:
$ go get -u -v github.com/btcsuite/btcd/...
$ go get -u -v github.com/btcsuite/btcwallet/...
Getting Started
The follow instructions detail how to get started with btcwallet connecting to a localhost btcd.
Windows (Installed from MSI)
Open Btcd Suite from the Btcd Suite menu in the Start
Menu. This will also open btcgui, which can be closed if you only
want btcd and btcwallet running.
Linux/BSD/POSIX/Source
- Run the following command to start btcd:
$ btcd --testnet -u rpcuser -P rpcpass
- Run the following command to start btcwallet:
$ btcwallet -u rpcuser -P rpcpass
If everything appears to be working, it is recommended at this point to copy the sample btcd and btcwallet configurations and update with your RPC username and password.
$ cp $GOPATH/src/github.com/btcsuite/btcd/sample-btcd.conf ~/.btcd/btcd.conf
$ cp $GOPATH/src/github.com/btcsuite/btcwallet/sample-btcwallet.conf ~/.btcwallet/btcwallet.conf
$ $EDITOR ~/.btcd/btcd.conf
$ $EDITOR ~/.btcwallet/btcwallet.conf
Client Usage
Clients wishing to use btcwallet must connect to the ws endpoint
over a websocket connection. Messages sent to btcwallet over this
websocket are expected to follow the standard Bitcoin JSON API
(partially documented
here).
Websocket connections also enable additional API extensions and
JSON-RPC notifications (currently undocumented). The btcd packages
btcjson and btcws provide types and functions for creating and
JSON (un)marshaling these requests and notifications.
Issue Tracker
The integrated github issue tracker is used for this project.
GPG Verification Key
All official release tags are signed by Conformal so users can ensure the code has not been tampered with and is coming from Conformal. To verify the signature perform the following:
-
Download the public key from the Conformal website at https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt
-
Import the public key into your GPG keyring:
gpg --import GIT-GPG-KEY-conformal.txt -
Verify the release tag with the following command where
TAG_NAMEis a placeholder for the specific tag:git tag -v TAG_NAME
