libauth
LibAuth for Go - A modern authentication framework that feels as light as a library.
Example Usage
How to verify a valid, trusted token as chi middleware:
package main
import (
"net/http"
"github.com/go-chi/chi/v5"
"git.rootprojects.org/root/keypairs/keyfetch"
"git.rootprojects.org/root/libauth"
"git.rootprojects.org/root/libauth/chiauth"
)
func main() {
r := chi.NewRouter()
whitelist, err := keyfetch.NewWhitelist([]string{"https://therootcompany.github.io/libauth/"})
if nil != err {
panic(err)
}
tokenVerifier := chiauth.NewTokenVerifier(chiauth.VerificationParams{
Issuers: whitelist,
Optional: false,
})
r.Use(tokenVerifier)
r.Post("/api/users/profile", func(w http.ResponseWriter, r *http.Request) {
ctx := r.Context()
jws, ok := ctx.Value(chiauth.JWSKey).(*libauth.JWS)
if !ok || !jws.Trusted {
http.Error(w, "Unauthorized", http.StatusUnauthorized)
return
}
userID := jws.Claims["sub"].(string)
// ...
})
// ...
}
How to create a demo token with [keypairs][https://webinstall.dev/keypairs]:
my_key='./examples/privkey.ec.jwk.json'
my_claims='{
"iss": "https://therootcompany.github.io/libauth/",
"sub": "1",
"email_verified": false,
"email": "jo@example.com"
}'
keypairs sign \
--exp 1h \
"${my_key}" \
"${my_claims}" \
> jwt.txt
2> jws.json
How to pass an auth token:
pushd ./examples
go run ./server.go
my_token="$(cat ./examples/jwt.txt)"
curl -X POST http://localhost:3000/api/users/profile \
-H "Authorization: Bearer ${my_token}" \
-H 'Content-Type: application/json' \
--data-binary '{ "foo": "bar" }'
