Functions

func CreateFiles

func CreateFiles() (dbFile *os.File, dbDir string, err error)

CreateFiles creates the temporary directory and database file

func Decrypt

func Decrypt(data []byte, priv *rsa.PrivateKey) ([]byte, error)

DEPRECATED: use age instead Decrypt decrypts the given data using the given private key

func GetPrivateKeyPath

func GetPrivateKeyPath(conf *cfg.Config) (string, error)

func GetPublicKeyPath

func GetPublicKeyPath(conf *cfg.Config) (string, error)

GetPublicKeyPath returns the absolute path to the public key

Types

type CryptoStorage

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

cryptoStorage is a helper struct to create an instance of SQLite-cypher that implements fiber.Storage interface.

func CreateCryptoStorage

func CreateCryptoStorage(dbFile string) (conn *CryptoStorage, err error)

CreateCryptoStorage creates a SQLite-cypher encrypted storage for X25519 keys It needs to be called inside main function so that the temporary directory it uses is not discarded upon return.

func (*CryptoStorage) Close

func (s *CryptoStorage) Close() error

Close closes the storage.

func (*CryptoStorage) Conn

func (s *CryptoStorage) Conn() *sql.DB

func (*CryptoStorage) Delete

func (s *CryptoStorage) Delete(key string) error

Delete deletes a key in the storage.

func (*CryptoStorage) Get

func (s *CryptoStorage) Get(key string) ([]byte, error)

Get returns the value of a key in the storage.

func (*CryptoStorage) Reset

func (s *CryptoStorage) Reset() error

Reset resets the storage, removing all keys.

func (*CryptoStorage) Set

func (s *CryptoStorage) Set(key string, val []byte, exp time.Duration) error

Set sets the value of a key in the storage. If the key does not exist, it will be created.

type Keys

type Keys struct {
	Identifier uuid.UUID
	Private    *age.X25519Identity
	Public     *age.X25519Recipient
}

Keys holds the information used for volatile identification of a particular user

func GenerateKeys

func GenerateKeys() (k Keys, e error)

@function GenerateKeys @description Generates a (volatile) public and private key pair to be used for intermediary encryption in the frontend @returns Keys, error NOTE: should probably also expect some persistent key based identification to be passed as a parameter to make impersonation harder
