Functions

func DecryptPathItems

func DecryptPathItems(key []byte, path string, encryptedReader io.Reader) (string, io.ReadCloser, error)

DecryptPathItems returns a decrypted path string and an io.Reader that reads the decrypted data from the encrypted reader passed into the function. To only decrypt a path, pass in an empty byte buffer as the reader and check only for the string result.

NOTE: key must be a 64 byte long key

func EncryptPathItems

func EncryptPathItems(key []byte, path string, plainReader io.Reader) (string, io.Reader, error)

EncryptPathItems returns an encrypted path and a Reader that reads the encrypted data from the plain reader passed into the function. Encrypted data is AES-CTR of data + AES-512 HMAC of encrypted data

NOTE: key must be a 64 byte long key To decrypt the result of this function use the DecryptPathItems function

func NewDecryptReader

func NewDecryptReader(r io.Reader, aesKey, iv, hmacKey []byte) (io.ReadCloser, error)

NewDecryptReader creates an io.ReadCloser wrapping an io.Reader using the keys and iv to decode the content using AES and verify HMAC.

func NewEncryptReader

func NewEncryptReader(r io.Reader, aesKey, iv, hmacKey []byte) (io.Reader, error)

NewEncryptReader returns an io.Reader wrapping the provided io.Reader.
