Hello,
I encountered an issue with the following code:
```go
dongle.Encrypt.FromString("hello world").ByMd5().ToString()
```
golang version: **such as 1.16**
dongle version: **such as 1.0.0**
I expected to get:
```
5eb63bbbe01eeed093cb22bb8f5acdc3
```
But I actually get:
```
014f03f9025ea81a8a0e9734be540c53
```
Thanks!

## 项目简介
`Dongle` 是一个轻量级、语义化、对开发者友好的 `golang` 编码&密码库，`100%` 单元测试覆盖率，已被 [awesome-go](https://github.com/yinggaozhen/awesome-go-cn#安全 "awesome-go-cn") 收录，并获得
`gitee` 2024 年最有价值项目（`GVP`）和 `gitcode` 2024 年度开源摘星计划 (`G-Star`) 项目
## 仓库地址
[github.com/dromara/dongle](https://github.com/dromara/dongle "github.com/dromara/dongle")
[gitee.com/dromara/dongle](https://gitee.com/dromara/dongle "gitee.com/dromara/dongle")
[gitcode.com/dromara/dongle](https://gitcode.com/dromara/dongle "gitcode.com/dromara/dongle")
## 快速开始
### 安装使用
> go version >= 1.23
```go
// 使用 github 库
go get -u github.com/dromara/dongle
// 使用 gitee 库
go get -u gitee.com/dromara/dongle
// 使用 gitcode 库
go get -u gitcode.com/dromara/dongle
```
`Dongle` 已经捐赠给了 [dromara](https://dromara.org/ "dromara") 开源组织，仓库地址发生了改变，如果之前用的路径是
`golang-module/dongle`，请在 `go.mod` 里将原地址更换为新路径，或执行如下命令
```go
go mod edit -replace github.com/golang-module/dongle = github.com/dromara/dongle
```
### 用法示例
编码、解码(以 `Base64` 为例)
```go
import (
"github.com/dromara/dongle"
)
dongle.Encode.FromString("hello world").ByBase64().ToString() // aGVsbG8gd29ybGQ=
dongle.Decode.FromString("aGVsbG8gd29ybGQ=").ByBase64().ToString() // hello world
```
Hash 算法(以 `Md5` 为例)
```go
import (
"github.com/dromara/dongle"
)
dongle.Hash.FromString("hello world").ByMd5().ToHexString() // 5eb63bbbe01eeed093cb22bb8f5acdc3
dongle.Hash.FromString("hello world").ByMd5().ToBase64String() // XrY7u+Ae7tCTyyK7j1rNww==
```
Hmac 算法(以 `Md5` 为例)
```go
import (
"github.com/dromara/dongle"
)
dongle.Hash.FromString("hello world").WithKey([]byte("dongle")).ByMd5().ToHexString() // 4790626a275f776956386e5a3ea7b726
dongle.Hash.FromString("hello world").WithKey([]byte("dongle")).ByMd5().ToBase64String() // R5Biaidfd2lWOG5aPqe3Jg==
```
对称加密(以 `AES` 为例)
```go
import (
"github.com/dromara/dongle"
"github.com/dromara/dongle/crypto/cipher"
)
// 创建密钥器
c := cipher.NewAesCipher(cipher.CBC)
// 设置密钥（16 字节)
c.SetKey([]byte("dongle1234567890"))
// 设置初始化向量（16 字节)
c.SetIV([]byte("1234567890123456"))
// 设置填充模式（只有 CBC/ECB 分组模式才需要设置填充模式）
c.SetPadding(cipher.PKCS7)
// 对字符串明文进行加密, 返回 hex 编码字符串密文
dongle.Encrypt.FromString("hello world").ByAes(c).ToHexString() // 48c6bc076e1da2946e1c0e59e9c91ae9
// 对字符串明文进行加密, 返回 base64 编码字符串密文
dongle.Encrypt.FromString("hello world").ByAes(c).ToBase64String() // SMa8B24dopRuHA5Z6cka6Q==
// 对 hex 编码字符串密文进行解密, 返回字符串明文
dongle.Decrypt.FromHexString("48c6bc076e1da2946e1c0e59e9c91ae9").ByAes(c).ToString() // hello world
// 对 base64 编码字符串密文进行解密, 返回字符串明文
dongle.Decrypt.FromBase64String("SMa8B24dopRuHA5Z6cka6Q==").ByAes(c).ToString() // hello world
```
非对称加密(以 `RSA` 为例)
```go
import (
"crypto"
"github.com/dromara/dongle"
"github.com/dromara/dongle/crypto/keypair"
)
// 创建密钥对

## Quick Start
### Installation
> go version >= 1.23
```go
// Via github
go get -u github.com/dromara/dongle
// Via gitee
go get -u gitee.com/dromara/dongle
// Via gitcode
go get -u gitcode.com/dromara/dongle
```
`Dongle` was donated to the [dromara](https://dromara.org/ "dromara") organization, the repository URL has changed. If
the previous repository used was `golang-module/dongle`, please replace the original repository with the new repository
in `go.mod`, or execute the following command:
```go
go mod edit -replace github.com/golang-module/dongle = github.com/dromara/dongle
```
### Example Usage
Encode&Decode(using `Base64` as an example)
```go
import (
"github.com/dromara/dongle"
)
dongle.Encode.FromString("hello world").ByBase64().ToString() // aGVsbG8gd29ybGQ=
dongle.Decode.FromString("aGVsbG8gd29ybGQ=").ByBase64().ToString() // hello world
```
