branca.go is branca token specification implementation for Go 1.18+.

Features and benefits:

Installation

Make sure you have a working Go 1.18+ 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.
