Md5 hash di php dan c++






  29-Jun-2020 22:29:27



Selamat malam,kali ini saya akan memberikan contoh membuat md5 dengan menggunakan bahasa php dan c++.

Saya mulai ke php dulu.

1.Php

Source code :

<?php
echo "MD5 Hash php\n";
echo "Masukkan Teks : ";
$teks = trim(fgets(STDIN));
echo "Hasil = ",md5($teks);
?>

2.C++

A.Siapkan file md5nya terlebih dahulu.

/* MD5
 converted to C++ class by Frank Thilo (thilo@unix-ag.org)
 for bzflag (http://www.bzflag.org)

   based on:

   md5.h and md5.c

  uint4 count[2];   // 64bit counter for number of bits (lo, hi)
  uint4 state[4];   // digest so far

  // low level logic operations
  static inline uint4 F(uint4 x, uint4 y, uint4 z);
  static inline uint4 G(uint4 x, uint4 y, uint4 z);
  static inline uint4 H(uint4 x, uint4 y, uint4 z);
  static inline uint4 I(uint4 x, uint4 y, uint4 z);

  static inline void II(uint4 &a, uint4 b, uint4 c, uint4 d, uint4 x, uint4 s, uint4 ac);
};

std::string md5(const std::string str);

#endif

Setelah itu save dengan md5.h.Nanti file ini akan dipakai didalam main.cpp kita.

B.Siapkan file md5.cpp.Berikut source codenya.

Save dengan md5.cpp

C.Siapkan main.cpp kalian,Source code di bawah

#include <iostream>
#include "md5.h"

using namespace std;

int main()
{
    cout << "Hasil Hash Teks a : " <<md5("a");
    return 0;
}

Setlah itu kita compaile,sebelum compaile.File yang kita buat tadi harus satu path(folder),kemudian comapaile main.cpp kalian dengan md5.cpp kalian.Caranya seperti ini : g++ test.cpp md5.cpp -o test
NB : cara compaile tergantung kalian yang memberikan nama file tersebut,disini fle saya judulnya test.cpp dan md5.cpp. -o(objek/output) bebas dengan nama kalian masing - masing.

Output :


Sekian dari saya,apabila ada kata kurang jelas mohon maaf.
