Functions

func DecodeData

func DecodeData(privateKey []byte, data []byte, pkc ...int) ([]byte, error)

DecodeData 解密

	@param []byte => privateKey 私钥
	@param []byte => data 要解密的数据,如果数据进行过任何编码的请先解码
	@param ...int => pkc 私钥的编码方式 pkcs1 pkcs8
	@return []byte 解密内容
         error 错误信息

func DecodePrivateKey

func DecodePrivateKey(privateKey []byte, pkc ...int) (*rsa.PrivateKey, error)

DecodePrivateKey 解析私钥

func Decrypt

func Decrypt(privateKey []byte, data []byte, pkc ...int) ([]byte, error)

Decrypt RSA解密

func DecryptNoPadding

func DecryptNoPadding(privateKey *rsa.PrivateKey, data []byte) []byte

DecryptNoPadding NO_PADDING模式解密

func EncodeData

func EncodeData(publickey []byte, data []byte, elen ...int) ([]byte, error)

EncodeData 加密,数据如果过长将使用分段加密

	@param []byte => publickey 公钥数据
	@param []byte => data 需要加密的内容
	@param ...int => elen 数据分段加密长度,如果为空将按照密钥的能加密的最大长度分段
	@return []byte 加密结果
         error 错误信息

func Encrypt

func Encrypt(publickey []byte, data []byte) ([]byte, error)

Encrypt RSA加密
