)

Types

type Cell

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

Cell protects a secret of the size KeySize.

func New

func New(size int) (*Cell, error)

New returns a new Cell using at least size bytes to protect it.

func (*Cell) Free

func (c *Cell) Free()

Free the memory allocated for the cell.

func (*Cell) Store

func (c *Cell) Store(d []byte)

Store the secret d into the Cell. d needs to be KeySize bytes long.

func (*Cell) Update

func (c *Cell) Update() error

Update the cell with new random guard pages.

func (*Cell) With

func (c *Cell) With(f func([KeySize]byte) error) error

With executes f with the decrypted secret as a parameter.
