Go wrapper for BlockchainCommons' SLIP39 C implementation

Usage

Prerequisite

Get BlockchainCommons source code and compile it:

$ ./deps.sh

Headers will be placed into /usr/local/include/ and libraries in /usr/local/lib/.

Example - Create

Create a 3 of 5 Shamir Backup:

package main

import (
	"fmt"

	slip39 "github.com/rddl-network/bc-slip39-go"
)

func main() {
	groupThreshold := uint8(1)
	groups := []slip39.GroupDescriptor{
		{
			Threshold: 3,
			Count:     5,
		},
	}
	secret := []byte("totally secret!!")
	password := ""
	iterationExponent := uint8(0)
	resultCount, wordsInEachShare, sharesBuffer, err := slip39.Generate(groupThreshold, groups, secret, password, iterationExponent, slip39.Random())
	if err != nil {
		panic(err)
	}

	resultStrings := make([]string, resultCount)
	for index := 0; index < resultCount; index++ {
		start := index * wordsInEachShare
		end := start + wordsInEachShare
		words := sharesBuffer[start:end]
		resultString, err := slip39.StringsForWords(words, wordsInEachShare)
		if err != nil {
			panic(err)
		}
		resultStrings[index] = resultString
	}

	for _, resultString := range resultStrings {
		fmt.Printf("%s\n", resultString)
	}
}
