branca.go is branca token specification implementation for Go 1.23+.

Features and benefits:

• Pure Go implementation;
• No third-party dependencies at all;
• 100% code coverage;
• Fuzz tests.

Installation

Make sure you have a working Go 1.23+ workspace (instructions), then:

go get -u github.com/essentialkaos/branca/v2

Usage example

package main
import (   "fmt"      "github.com/essentialkaos/branca/v2" )
func main() {   key := "abcd1234abcd1234abcd1234abcd1234"   brc, err := branca.NewBranca([]byte(key))
if err != nil {     fmt.Printf("Error: %v\n", err)     return   }
payload := "MySuperSecretData"   token, err := brc.EncodeToString([]byte(payload))
if err != nil {     fmt.Printf("Error: %v\n", err)     return   }
fmt.Printf("Token: %s\n", token) }

Benchmarks

You can run benchmarks by yourself using make benchmark command.
