Functions

func RandomBytes

func RandomBytes(n int) ([]byte, error)

RandomBytes returns n random bytes by reading from crypto/rand.Reader

Types

type HMACStrategy

type HMACStrategy struct {
	sync.Mutex
	Config HMACStrategyConfigurator
}

HMACStrategy is responsible for generating and validating challenges.

func (*HMACStrategy) Generate

func (c *HMACStrategy) Generate(ctx context.Context) (string, string, error)

Generate generates a token and a matching signature or returns an error. This method implements rfc6819 Section 5.1.4.2.2: Use High Entropy for Secrets.

func (*HMACStrategy) GenerateHMACForString

func (c *HMACStrategy) GenerateHMACForString(ctx context.Context, text string) (string, error)

func (*HMACStrategy) Signature

func (c *HMACStrategy) Signature(token string) string

func (*HMACStrategy) Validate

func (c *HMACStrategy) Validate(ctx context.Context, token string) (err error)

Validate validates a token and returns its signature or an error if the token is not valid.

type HMACStrategyConfigurator

type HMACStrategyConfigurator interface {
	oauth2.TokenEntropyProvider
	oauth2.GlobalSecretProvider
	oauth2.RotatedGlobalSecretsProvider
	oauth2.HMACHashingProvider
}
