Install

go-eth2-wallet-store-filesystem is a standard Go module which can be installed with:

go get github.com/wealdtech/go-eth2-wallet-store-filesystem

Usage

In normal operation this module should not be used directly. Instead, it should be configured to be used as part of go-eth2-wallet.

The filesystem store has the following options:

• location: the base directory in which to store wallets. If this is not configured it defaults to a sensible operating system-specific values:
  • for Linux: $HOME/.config/ethereum2/wallets
  • for OSX: $HOME/Library/Application Support/ethereum2/wallets
  • for Windows: %APPDATA%\ethereum2\wallets
• passphrase: a key used to encrypt all data written to the store. If this is not configured data is written to the store unencrypted (although wallet- and account-specific private information may be protected by their own passphrases)

Example

package main

import (
	e2wallet "github.com/wealdtech/go-eth2-wallet"
	filesystem "github.com/wealdtech/go-eth2-wallet-store-filesystem"
)

func main() {
    // Set up and use a simple store
    store := filesystem.New()
    e2wallet.UseStore(store)

    // Set up and use an encrypted store
    store := filesystem.New(filesystem.WithPassphrase([]byte("my secret")))
    e2wallet.UseStore(store)

    // Set up and use an encrypted store at a custom location
    store := filesystem.New(filesystem.WithPassphrase([]byte("my secret")), filesystem.WithLocation("/home/user/wallets"))
    e2wallet.UseStore(store)

    // Use e2wallet operations as normal.
}
