Functions

func NewEAX

func NewEAX(c cipher.Block, tagsize int) (cipher.AEAD, error)

NewEAX returns a cipher.AEAD wrapping the cipher.Block. EAX is a two pass-scheme AEAD cipher with provable security. For authentication EAX uses CMac (OMAC1). The tagsize argument specifies the number of bytes of the auth. tag and must be between 1 and the block size of the cipher. This function returns a non-nil error if the given block cipher is not supported by CMac (see crypto/cmac for details)
