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)
}
