func EncryptFile

func EncryptFile(src, dst, key, macKey string) error

Types

type StreamDecrypter

type StreamDecrypter struct {
	Source io.Reader
	Block  cipher.Block
	Stream cipher.Stream
	MAC    hash.Hash
	Meta   StreamMeta
}

Stream Decrypter is a decrypter for a stream of data with authentication

func NewStreamDecrypter

func NewStreamDecrypter(key, macKey []byte, meta StreamMeta, cipherText io.Reader) (*StreamDecrypter, error)

Creates a new StreamDecrypter

func (*StreamDecrypter) Authenticate

func (s *StreamDecrypter) Authenticate() error

Verifies that the hash of the stream is correct. This should only be called after the processing is finished

func (*StreamDecrypter) Read

func (s *StreamDecrypter) Read(p []byte) (int, error)

Reads the byte from the reader and decrypts them

type StreamEncrypter

type StreamEncrypter struct {
	Source io.Reader
	Block  cipher.Block
	Stream cipher.Stream
	MAC    hash.Hash
	IV     []byte
}

Stream Encrypter is an encrypter for a stream of data with authentication

func NewStreamEncrypter

func NewStreamEncrypter(key, macKey []byte, plainText io.Reader) (*StreamEncrypter, error)

Creates a new Stream Encrypter

func (*StreamEncrypter) Meta

func (s *StreamEncrypter) Meta() StreamMeta

Returns the encrypted streams metadata for use in decrypting. This should be called after the stream is finished

func (*StreamEncrypter) Read

func (s *StreamEncrypter) Read(p []byte) (int, error)

Encrypts the bytes of the Source reader and and places them into p

type StreamMeta

type StreamMeta struct {
	//	Initialization Vector for the cryptographic function
	IV []byte
	//	HMAC hash of the stream
	Hash []byte
}
