Functions

func GenerateTransformer added in v0.27.0

func GenerateTransformer(ctx context.Context, uid string, envelopeService kmsservice.Service) (value.Transformer, *kmsservice.EncryptResponse, []byte, error)

func NewEnvelopeTransformer

func NewEnvelopeTransformer(envelopeService kmsservice.Service, providerName string, stateFunc StateFunc) value.Transformer

NewEnvelopeTransformer returns a transformer which implements a KEK-DEK based envelope encryption scheme. It uses envelopeService to encrypt and decrypt DEKs. Respective DEKs (in encrypted form) are prepended to the data items they encrypt.

func NewGRPCService

func NewGRPCService(ctx context.Context, endpoint, providerName string, callTimeout time.Duration) (kmsservice.Service, error)

NewGRPCService returns an envelope.Service which use gRPC to communicate the remote KMS provider.

Types

type ErrCodeKeyID added in v0.27.0

type ErrCodeKeyID string

func ValidateKeyID added in v0.27.0

func ValidateKeyID(keyID string) (ErrCodeKeyID, error)

ValidateKeyID tests the following: 1. The keyID is not empty. 2. The size of keyID is less than 1 kB.

type State added in v0.27.0

type State struct {
	Transformer  value.Transformer
	EncryptedDEK []byte
	KeyID        string
	Annotations  map[string][]byte

	UID string

	ExpirationTimestamp time.Time

	// CacheKey is the key used to cache the DEK in transformer.cache.
	CacheKey []byte
}

func (*State) ValidateEncryptCapability added in v0.27.0

func (s *State) ValidateEncryptCapability() error
