Functions

func NewSecret 

func NewSecret() (secret []byte, err error)

NewSecret generates cryptographically random 32 bytes

Types

type APIKey 

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

APIKey implements a Macaroon-backed Storj-v3 API key.

func NewAPIKey 

func NewAPIKey(secret []byte) (*APIKey, error)

NewAPIKey generates a brand new unrestricted API key given the provided server project secret

func ParseAPIKey 

func ParseAPIKey(key string) (*APIKey, error)

ParseAPIKey parses a given api key string and returns an APIKey if the APIKey was correctly formatted. It does not validate the key.

func (*APIKey) Check 

func (a *APIKey) Check(ctx context.Context, secret []byte, action Action, revoked [][]byte) (err error)

Check makes sure that the key authorizes the provided action given the root project secret and any possible revocations, returning an error if the action is not authorized. 'revoked' is a list of revoked heads.

func (*APIKey) Head 

func (a *APIKey) Head() []byte

Head returns the identifier for this macaroon's root ancestor.

func (*APIKey) Restrict 

func (a *APIKey) Restrict(caveat Caveat) (*APIKey, error)

Restrict generates a new APIKey with the provided Caveat attached.

func (*APIKey) Serialize 

func (a *APIKey) Serialize() string

Serialize serializes the API Key to a string

func (*APIKey) Tail 

func (a *APIKey) Tail() []byte

Tail returns the identifier for this macaroon only.

type Action 

type Action struct {
	Op            ActionType
	Bucket        []byte
	EncryptedPath []byte
	Time          time.Time
}

Action specifies the specific operation being performed that the Macaroon will validate

type ActionType 

type ActionType int

ActionType specifies the operation type being performed that the Macaroon will validate 

const (

	// ActionRead specifies a read operation
	ActionRead ActionType = 1
	// ActionWrite specifies a read operation
	ActionWrite ActionType = 2
	// ActionList specifies a read operation
	ActionList ActionType = 3
	// ActionDelete specifies a read operation
	ActionDelete ActionType = 4
	// ActionProjectInfo requests project-level information
	ActionProjectInfo ActionType = 5
)

type Caveat 

type Caveat struct {
	// if any of these three are set, disallow that type of access

	NotBefore *time.Time `protobuf:"bytes,21,opt,name=not_before,json=notBefore,proto3,stdtime" json:"not_before,omitempty"`
	// nonce is set to some random bytes so that you can make arbitrarily
	// many restricted macaroons with the same (or no) restrictions.
	Nonce                []byte   `protobuf:"bytes,30,opt,name=nonce,proto3" json:"nonce,omitempty"`
