func NewEAX ¶

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

NewEAX returns an EAX instance with AES-{KEYLENGTH} and default nonce and tag lengths. Supports {128, 192, 256}- bit key length.

func NewEAXWithNonceAndTagSize ¶

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

NewEAXWithNonceAndTagSize returns an EAX instance with AES-{keyLength} and given nonce and tag lengths in bytes. Panics on zero nonceSize and exceedingly long tags.

It is recommended to use at least 12 bytes as tag length (see, for instance, NIST SP 800-38D).

Only to be used for compatibility with existing cryptosystems with non-standard parameters. For all other cases, prefer NewEAX.

func NewEAXWithNonceSize ¶

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

func NewEAXWithTagSize ¶

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