branca is a secure alternative to JWT, This implementation is written in pure Go (no cgo dependencies) and implements the branca token specification.
Go 1.13+
go get -u github.com/hako/branca
package main
import (
"fmt"
"github.com/hako/branca"
)
func main() {
b := branca.NewBranca("supersecretkeyyoushouldnotcommit") // This key must be exactly 32 bytes long.
// Encode String to Branca Token.
token, err := b.EncodeToString("Hello world!")
if err != nil {
fmt.Println(err)
}
//b.SetTTL(3600) // Uncomment this to set an expiration (or ttl) of the token (in seconds).
//token = "87y8daMzSkn7PA7JsvrTT0JUq1OhCjw9K8w2eyY99DKru9FrVKMfeXWW8yB42C7u0I6jNhOdL5ZqL" // This token will be not allowed if a ttl is set.
// Decode Branca Token.
message, err := b.DecodeToString(token)
if err != nil {
fmt.Println(err) // token is expired.
return
}
fmt.Println(token) // 87y8da....
fmt.Println(message) // Hello world!
}Here are a few things that need to be done:
- Remove cgo dependencies.
- Move to a pure XChaCha20 algorithm in Go.
- Add more tests than just acceptance tests.
- Increase test coverage.
- Additional Methods. (Encode, Decode []byte)
- Performance benchmarks.
- More comments, examples and documentation.
