Types

type Bulla

type Bulla struct {
	Content []byte
	Salt    []byte
}

Bulla is the name for the hash returned by the stamp function. The Bulla can be used as a `key` in symmetric encryption.

type Scrypt

type Scrypt struct {
	// n and r control scrypt's memory requirements
	N int
	R int
	// p controls whether scrypt can run on multiple processors
	P int
	// length in bytes
	Length                int
	EntropyImplementation entropy.Entropy
}

func (*Scrypt) Stamp

func (s *Scrypt) Stamp(postage mailbag.Postage) (*mailbag.Bulla, error)

type Stamper

type Stamper interface {
	Stamp(mailbag.Postage) (*mailbag.Bulla, error)
