Description

You could use the expand.exe generate passphase、private key、address to the database（redis) such as bitcoin or ethereum,you also can custom made any other kind,for example,if you want to addin litecoin to the progrom,you just need complete the interface as below:

type TokenModule interface {
　　Name() string
　　KeyBitLen() int
　　GetWIF([]byte) (string, error)
　　GetAddress([]byte) (string, error)
}
then add an opt "ltc" to the start param 'token'.
Similarly,you can custom make your own passphase generate module、private key generate module.

Building

Building requires go (version 1.9.2 or later)
Ensure
1 "github.com/garyburd/redigo/redis"
2 "github.com/btcsuite"
3 "github.com/ethereumm/go-ethereum"
and their dependencies are in your path "$GOPATH/src"

Run

You need run redis(version 3.2.100 or later) on your mechine,you can use the script "start_redis.bat" to start redis locally.
After redis start,you can run expand.exe on shell use default params.

./expand.exe

or

./expand.exe --help

see the params like this:
