Functions

func Write

func Write(connector Connector, fileInfo *dirent.Dirent,
	blockCipher cipher.Block, clearbytes io.Reader) (uint64, string, error)

A convenience function for synchronious writes. Returns: (size, md5 hash (hex), error).

Types

type Connector

type Connector interface {
	// Every connector should be able to construct a unique id for itself
	// that is the same for each backend.
	GetId() string
	// Prepare the backend storage for initialization.
	PrepareStorage() error
	// Get a reader that transparently handles all decryption.
	GetCipherReader(fileInfo *dirent.Dirent, blockCipher cipher.Block) (util.ReadSeekCloser, error)
	// Metadata may be stored in a different way than normal files.
