Functions ¶
func Decrypt ¶
func Decrypt(key *PrivateKey, ciphertext *Ciphertext) *bn256.GT
func DecryptHibeMsg ¶
func DecryptHibeMsg(localId string, hibeParams *Params, prvKey *PrivateKey, hibeMsgMap map[string]string, symKeyType crypto.KeyType) ([]byte, error)
DecryptHibeMsg is used to decrypt the HIBE message constructed by EncryptHibeMsg localId: hibe Id hibeParams: HIBE parameters of the HIBE system to which ID belongs prvKey: the localId's hibe private Key hibeMsgMap: HIBE message encrypt by EncryptHibeMsg symKeyType: symmetric key type (aes or sm4), used to symmetric encrypt the plain text first
func EncryptHibeMsg ¶
func EncryptHibeMsg(plaintext []byte, receiverIds []string, paramsList []*Params, symKeyType crypto.KeyType) (map[string]string, error)
EncryptHibeMsg is used to encrypt plainText by receiverIds and their paramsList plaintext: plain text bytes receiverIds: message receivers' id list, using "/" to separate hierarchy identity in each id string paramsList: HIBE parameters list of the message receiver, len(paramsList) should be equal to len(receiverIds),
paramsList[i] are the HIBE parameters of receiverIds[i]
symKeyType: symmetric key type (aes or sm4), used to symmetric encrypt the plain text first
func IdStr2HibeId ¶
IdStr2HibeId construct HibeId according to id
Types ¶
type Ciphertext ¶
type Ciphertext = hibe.Ciphertext
type PrivateKey ¶
type PrivateKey = hibe.PrivateKey
func KeyGenFromMaster ¶
func KeyGenFromParent ¶
func KeyGenFromParent(random io.Reader, params *Params, parent *PrivateKey, id []*big.Int) (*PrivateKey, error)
