Functions ¶
func GenerateKey ¶
GenerateKey generates a new Key with given algorithm for AES-CCM.
func MaxNonceLength ¶ added in v1.1.3
MaxNonceLength returns the maximum nonce length for a given plaintext length. A return value <= 0 indicates that plaintext length is too large for any nonce length.
Types ¶
type CCM ¶ added in v1.1.3
type CCM interface {
cipher.AEAD
// MaxLength returns the maxium length of plaintext in calls to Seal.
// The maximum length of ciphertext in calls to Open is MaxLength()+Overhead().
// The maximum length is related to CCM's `L` parameter (15-noncesize) and
// is 1<<(8*L) - 1 (but also limited by the maxium size of an int).
MaxLength() int
}
CCM is a block cipher in Counter with CBC-MAC mode. Providing authenticated encryption with associated data via the cipher.AEAD interface.
