Functions

func CRandBytes 

func CRandBytes(numBytes int) []byte

CRandBytes This uses the OS and the Seed(s).

func CRandHex 

func CRandHex(numDigits int) string

CRandHex RandHex(24) gives 96 bits of randomness, strong enough for most purposes.

func CReader 

func CReader() io.Reader

CReader Returns a crand.Reader mixed with user-supplied entropy

func GetName 

func GetName(ty int) string

GetName 获取name

func GetType 

func GetType(name string) int

GetType 获取type

func MixEntropy 

func MixEntropy(seedBytes []byte)

MixEntropy Mix additional bytes of randomness, e.g. from hardware, user-input, etc. It is OK to call it multiple times. It does not diminish security.

func Register 

func Register(name string, driver Crypto, isCGO bool)

Register 注册加密算法，允许同种加密算法的cgo版本同时注册

func RegisterType 

func RegisterType(name string, ty int)

RegisterType 注册类型

func Ripemd160 

func Ripemd160(bytes []byte) []byte

Ripemd160 加密算法

func Sha256 

func Sha256(bytes []byte) []byte

Sha256 加密算法

func Sm3Hash 

func Sm3Hash(msg []byte) []byte

Sm3Hash 加密算法

Types

type AggregateCrypto added in v1.65.0 

type AggregateCrypto interface {
	Aggregate(sigs []Signature) (Signature, error)
	AggregatePublic(pubs []PubKey) (PubKey, error)
	VerifyAggregatedOne(pubs []PubKey, m []byte, sig Signature) error
	VerifyAggregatedN(pubs []PubKey, ms [][]byte, sig Signature) error
}

AggregateCrypto 聚合签名

func ToAggregate added in v1.65.0 

func ToAggregate(c Crypto) (AggregateCrypto, error)

ToAggregate 判断签名是否可以支持聚合签名，并且返回聚合签名的接口

type CertSignature 

type CertSignature struct {
	Signature []byte
	Cert      []byte
}

CertSignature 签名

type Crypto 

type Crypto interface {
	GenKey() (PrivKey, error)
	SignatureFromBytes([]byte) (Signature, error)
	PrivKeyFromBytes([]byte) (PrivKey, error)
	PubKeyFromBytes([]byte) (PubKey, error)
}

Crypto 加密

func New 

func New(name string) (c Crypto, err error)

New new

type PrivKey 

type PrivKey interface {
	Bytes() []byte
	Sign(msg []byte) Signature
	PubKey() PubKey
	Equals(PrivKey) bool
}

PrivKey 私钥

type PubKey 

type PubKey interface {
	Bytes() []byte
	KeyString() string
	VerifyBytes(msg []byte, sig Signature) bool
	Equals(PubKey) bool
}

PubKey 公钥

type Signature 

type Signature interface {
	Bytes() []byte
	IsZero() bool
	String() string
	Equals(Signature) bool
}

Signature 签名
