Constants

const ExpiresDuration = 24 * time.Hour

ExpiresDuration is the duration when a user session expires.

Types

type Claims

type Claims struct {
	jwt.RegisteredClaims
	UserID   string `json:"user_id"`
	UserName string `json:"user_name"`
	Nonce    string `json:"nonce"`
}

Claims are the fields stored in a JWT.

type Service

type Service struct {
	Secret []byte
	Nonces nonce.Repository
}

Service handles common JWT manipulation.

func (*Service) GenerateToken

func (s *Service) GenerateToken(
	ctx context.Context,
	userID string,
	userName string,
	long bool,
) (claims *Claims, signed string)

GenerateToken creates a JWT session token which stores the user identity.

The returned token is signed with the JWT secret, meaning it cannot be falsified.

func (*Service) VerifyToken

func (s *Service) VerifyToken(ctx context.Context, tokenString string) (*Claims, error)

VerifyToken checks if the token signature is valid compared to the JWT secret.
