Functions

func HashAuth(salter *salt.Salt, in *logical.Auth, HMACAccessor bool) (*logical.Auth, error)

HashAuth returns a hashed copy of the logical.Auth input.

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
	Invalidate(context.Context)
}

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

	// The salt config that should be used for any secret obfuscation
	SaltConfig *salt.Config

	// Config is the opaque user configuration provided when mounting
	Config map[string]string
}

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
}

Formatter is an interface that is responsible for formatting a request/response into some format. Formatters write their output to an io.Writer.

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

type FormatterConfig added in v0.6.2 

type FormatterConfig struct {
	Raw          bool
	HMACAccessor bool

	// Vault lacks pagination in its APIs. As a result, certain list operations can return **very** large responses.
	// The user's chosen audit sinks may experience difficulty consuming audit records that swell to tens of megabytes
	// of JSON. The responses of list operations are typically not very interesting, as they are mostly lists of keys,
	// or, even when they include a "key_info" field, are not returning confidential information. They become even less
	// interesting once HMAC-ed by the audit system.
	//
	// Some example Vault "list" operations that are prone to becoming very large in an active Vault installation are:
	//   auth/token/accessors/
	//   identity/entity/id/
	//   identity/entity-alias/id/
	//   pki/certs/
	//
	// This option exists to provide such users with the option to have response data elided from audit logs, only when
	// the operation type is "list". For added safety, the elision only applies to the "keys" and "key_info" fields
	// within the response data - these are conventionally the only fields present in a list response - see
	// logical.ListResponse, and logical.ListResponseWithInfo. However, other fields are technically possible if a
	// plugin author writes unusual code, and these will be preserved in the audit log even with this option enabled.
	// The elision replaces the values of the "keys" and "key_info" fields with an integer count of the number of
	// entries. This allows even the elided audit logs to still be useful for answering questions like
	// "Was any data returned?" or "How many records were listed?".
	ElideListResponses bool

	// This should only ever be used in a testing context
	OmitTime bool
}
