type Backend

type Backend interface {
	// LogRequest is used to synchronously log a request. This is done after the
	// request is authorized but before the request is executed. The arguments
	// MUST not be modified in anyway. They should be deep copied if this is
	// a possibility.
	LogRequest(context.Context, *logical.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
	// MUST not be modified in anyway. They should be deep copied if this is
	// a possibility.
	LogResponse(context.Context, *logical.LogInput) error

	// LogTestMessage is used to check an audit backend before adding it
	// permanently. It should attempt to synchronously log the given test
	// message, WITHOUT using the normal Salt (which would require a storage
	// operation on creation, which is currently disallowed.)
	LogTestMessage(context.Context, *logical.LogInput, map[string]string) error

	// GetHash is used to return the given data with the backend's hash,
	// so that a caller can determine if a value in the audit log matches
	// an expected plaintext value
	GetHash(context.Context, string) (string, error)

	// Reload is called on SIGHUP for supporting backends.
	Reload(context.Context) error

	// Invalidate is called for path invalidation

}

Backend interface must be implemented for an audit mechanism to be made available. Audit backends can be enabled to sink information to different backends such as logs, file, databases, or other external services.

type BackendConfig added in v0.3.0

type BackendConfig struct {
	// The view to store the salt
	SaltView logical.Storage

BackendConfig contains configuration parameters used in the factory func to instantiate audit backends

type Factory

type Factory func(context.Context, *BackendConfig) (Backend, error)

Factory is the factory function to create an audit backend.

type Formatter

type Formatter interface {
	FormatRequest(context.Context, io.Writer, FormatterConfig, *logical.LogInput) error
	FormatResponse(context.Context, io.Writer, FormatterConfig, *logical.LogInput) error

It is recommended that you pass data through Hash prior to formatting it.

	Raw          bool
	HMACAccessor bool
