Functions

func New

func New(block cipher.Block) (cipher.AEAD, error)

New returns an OCB instance with the given block cipher and default tag and nonce sizes.

func NewWithNonceAndTagSize

func NewWithNonceAndTagSize(
	block cipher.Block,
	nonceSize int,
	tagSize int,
) (cipher.AEAD, error)

NewWithNonceAndTagSize returns an OCB instance with the given block cipher, nonce length, and tag length. Panics on zero nonceSize and exceedingly long tag size.

It is recommended to use at least 12 bytes as tag length.

func NewWithNonceSize

func NewWithNonceSize(block cipher.Block, nonceSize int) (cipher.AEAD, error)

func NewWithTagSize

func NewWithTagSize(block cipher.Block, tagSize int) (cipher.AEAD, error)
