# multiaddr/net - Multiaddr friendly net
Package multiaddr/net provides [Multiaddr](http://github.com/jbenet/go-multiaddr) specific versions of common
functions in stdlib's net package. This means wrappers of
standard net symbols like net.Dial and net.Listen, as well
as conversion to/from net.Addr.
Docs:
- `multiaddr/net`: https://godoc.org/github.com/jbenet/go-multiaddr-net
- `multiaddr`: https://godoc.org/github.com/jbenet/go-multiaddr

# go-base58
I extracted this package from https://github.com/conformal/btcutil to provide a simple base58 package that
- defaults to base58-check (btc)
- and allows using different alphabets.
## Usage
```go
package main
import (
"fmt"
b58 "github.com/jbenet/go-base58"
)
func main() {
buf := []byte{255, 254, 253, 252}
fmt.Printf("buffer: %v\n", buf)
str := b58.Encode(buf)
fmt.Printf("encoded: %s\n", str)
buf2 := b58.Decode(str)
fmt.Printf("decoded: %v\n", buf2)
}
```
### Another alphabet
```go
package main
import (
"fmt"
b58 "github.com/jbenet/go-base58"
)
const BogusAlphabet = "ZYXWVUTSRQPNMLKJHGFEDCBAzyxwvutsrqponmkjihgfedcba987654321"
func encdec(alphabet string) {
fmt.Printf("using: %s\n", alphabet)
buf := []byte{255, 254, 253, 252}
fmt.Printf("buffer: %v\n", buf)
str := b58.EncodeAlphabet(buf, alphabet)
fmt.Printf("encoded: %s\n", str)
buf2 := b58.DecodeAlphabet(str, alphabet)
fmt.Printf("decoded: %v\n\n", buf2)
}
func main() {
encdec(b58.BTCAlphabet)
encdec(b58.FlickrAlphabet)
encdec(BogusAlphabet)
}
```
