###Dependencies

1. Linux

2. g++ and GNU make

###How to Run Tests

1. Edit the Makefile, make sure `CFLAGS=-c -g -Wall -DSAMPLE_TEST`

2. If you have built the program before, run `make clean`

3. In the project directory, run `make`

4. In the project directory, run `./md5`

###How to Use It As a Program

1. Edit the Makefile, make sure `CFLAGS=-c -g -Wall`

2. If you have built the program before, run `make clean`

3. In the project directory, run `make`

4. In the project directory, run `./md5`

5. Enter strings into stdin, the results will be output to stdout

If you want to use redirection, this is an example. (Checkout the `test` target in Makefile)

```bash

./md5 < testcase/in > testcase/result

```

###API

* `string md5(const string str)`

  Sample usage:

  ```cpp

  #include 

  #include "md5.h"

  using namespace joyee;

  int main(int argc, char* argv[]) {

    std::cout << md5("abc") << '\n'; // 900150983cd24fb0d6963f7d28e17f72

    return 0;

  }

  ```

* `update`, `finalize`, `toString`

  Sample usage:

  ```cpp

  #include 

  #include 

  #include "md5.h"

  using namespace joyee;

  int main(int argc, char* argv[]) {

    MD5 md5 = MD5();

    int data = 1234;

    md5.update(reinterpret_cast(&data), sizeof(data));

    md5.finalize();

    std::cout << md5.toString() << '\n'; // 099c28f29510c7938bc8c307d287557f

    return 0;

  }

  ```
