Types

type Claims 

type Claims struct {
	Hash      string `json:"covidtrace:hash"`
	Refreshed int    `json:"covidtrace:refreshed"`
	jwt.StandardClaims
}

Claims represents the JWT claims covidtrace cares about

type Issuer 

type Issuer struct {
	// contains filtered or unexported fields
}

Issuer is the core covidtrace/jwt type. It exposes methods to issue and verify tokens.

func NewIssuer 

func NewIssuer(key []byte, iss, aud string, dur time.Duration) *Issuer

NewIssuer returns, well, a new `Issuer`

func (*Issuer) Claims 

func (i *Issuer) Claims(hash string, refresh int) *Claims

Claims constructs a new Claims object, filling details in from i

func (*Issuer) Token 

func (i *Issuer) Token(hash string, refresh int) (string, error)

Token handles generating a signed JWT token with the given `hash` and `refresh` count

func (*Issuer) Validate 

func (i *Issuer) Validate(signedString string) (*Claims, error)

Validate handles ensuring `signedString` is a valid JWT issued by this issuer. It returns the `hash` and `refreshed` claims, or an `error` if the token is invalid
