Types

type Crypto

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

func NewCrypto

func (*Crypto) Argon2ID

func (c *Crypto) Argon2ID(data []byte, time, memory uint32) (digest [argon2IDDigestSize]byte)

func (*Crypto) Checksumize

func (c *Crypto) Checksumize(data []byte) (checksumedData []byte, err error)

Checksumize adds a Shake 256 checksum to some data.

func (*Crypto) Dechecksumize

func (c *Crypto) Dechecksumize(checksumData []byte) (data []byte, err error)

Dechecksumize verifies the Shake 256 checksum of some data.
