Types

type Config

type Config struct {
	HashFunc     func() hash.Hash
	Random       io.Reader
	CipherSuites []byte
}

Config contains configurations of crypt

type Decrypter

type Decrypter struct {
	PrivateKey *rsa.PrivateKey
	Config     *Config
}

Decrypter can decrypt data with RSA private key

func NewDecrypter

func NewDecrypter(privateKey []byte, config *Config) (*Decrypter, error)

NewDecrypter create a new decrypter

func (*Decrypter) DecryptData

func (dec *Decrypter) DecryptData(dataReader io.Reader) (*bytes.Buffer, error)

DecryptData will decrypt data from certain data format

type Encrypter

type Encrypter struct {
	PublicKey *rsa.PublicKey
	Config    *Config
}

Encrypter can encrypt data with RSA public key

func NewEncrypter

func NewEncrypter(publicKey []byte, config *Config) (*Encrypter, error)

NewEncrypter create a new encrypter

func (*Encrypter) EncryptData

func (enc *Encrypter) EncryptData(dataReader io.Reader) (*bytes.Buffer, error)

EncryptData will Encrypt data from certain data format
