		PrivateKeyType:     gocrypt.PKCS1,
		PrivateKeyDataType: gocrypt.Base64,
	}

2.构造handle

handle, err := gocrypt.NewCrypt(gocrypt.RSA, secretInfo)
	if err != nil {
		fmt.Println("new error :", err)
		return
	}

3.加密、解密、签名、验签

（1）加密

加密指定字符串，并以指定编码格式输出结果

encrypt, err := handle.Encrypt("test", gocrypt.HEX)
	if err != nil {
		fmt.Println("encrypt error :", err)
		return
	}
	fmt.Println("encrypt data :", encrypt)
（2）解密

解密指定格式编码后的加密串，返回原字符串

	decrypt, err := handle.Decrypt(encrypt, gocrypt.HEX)
	if err != nil {
		fmt.Println("decrypt error :", err)
		return
	}
	fmt.Println("decrypt data :", decrypt)
（3）签名

以指定摘要算法签名，并以指定编码格式输出结果

	sign, err := handle.Sign("test", gocrypt.SHA256, gocrypt.HEX)
	if err != nil {
		fmt.Println("sign error :", err)
		return
	}
	fmt.Println("sign data :", sign)
（4）验签

验证字符串是否是以指定摘要算法编码的签名串的原始字符串

	verifySign, err := handle.VerifySign("test", gocrypt.SHA256, sign, gocrypt.HEX)
	if err != nil {
		fmt.Println("verifySign error :", err)
		return
	}
	fmt.Println("verifySign result :", verifySign)
