Functions

func Hash 

func Hash(salter *salt.Salt, raw interface{}, nonHMACDataKeys []string) error

Hash will hash the given type. This has built-in support for auth, requests, and responses. If it is a type that isn't recognized, then it will be passed through.

The structure is modified in-place.

func HashString added in v0.4.0 

func HashString(salter *salt.Salt, data string) string

HashString hashes the given opaque string and returns it

func HashStructure 

func HashStructure(s interface{}, cb HashCallback, ignoredKeys []string) (interface{}, error)

HashStructure takes an interface and hashes all the values within the structure. Only _values_ are hashed: keys of objects are not.

For the HashCallback, see the built-in HashCallbacks below.

	// MUST not be modified in anyway. They should be deep copied if this is
	// a possibility.
	LogRequest(context.Context, *LogInput) error

	// LogResponse is used to synchronously log a response. This is done after
	// the request is processed but before the response is sent. The arguments

	// a possibility.
