Functions

func NewOCB

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

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

func NewOCBWithNonceAndTagSize

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

NewOCBWithNonceAndTagSize 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.
