试图端口C＃函数PHP5 [英] Trying to port C# function to PHP5

问题描述

我想这个功能到PHP转换，但不知它不会给相同的结果。

 公共静态字符串EncodePassword （字符串传递，字符串盐）{
字节[]字节= Encoding.Unicode.GetBytes（PASS）; 
的byte [] SRC = Convert.FromBase64String（盐）; 
字节[] = DST新的字节[src.Length + bytes.Length]; 
的byte [] inArray = NULL; 
 Buffer.BlockCopy（源，0，dst的，0，src.Length）; 
 Buffer.BlockCopy（字节，0，DST，src.Length，bytes.Length）; 
算法的HashAlgorithm = HashAlgorithm.Create（SHA1）; 
 inArray = algorithm.ComputeHash（DST）; 
返回Convert.ToBase64String（inArray）; 
} 
  

这是我对在PHP

 函数CreatePasswordHash（$的密码，$盐）{
 $ salted_pa​​ssword = BASE64_DECODE（$盐）$的密码; 
 $结果=散列（'SHA1'，$ salted_pa​​ssword，真正的）; 
返回BASE64_ENCODE（$结果）; 
} 
  

当然，这是行不通的。 ？所以我在做什么错在这里。

这些都是值来进行测试：

  $盐='Xh2pHwDv3VEUQCvz5qOm7w =='; 
 $ hashed_value ='0U / kYMz3yCXLsw / r9kocT5zf0cc ='; 
 $密码='Welcome1！; 
 
如果（$ hashed_value === CreatePasswordHash（$的密码，$盐））{
回声干得好！ 
} 
  

编辑：基于来自Martyx和休闲裤的建议工作液

 函数CreatePasswordHash（$的密码，$盐）{
 $ upass = mb_convert_encoding（$的密码，UCS-2LE'，'汽车' ）; 
 $ salted_pa​​ssword = BASE64_DECODE（$盐）$ upass。 
 $结果=散列（'SHA1'，$ salted_pa​​ssword，真正的）; 
返回BASE64_ENCODE（$结果）; 
} 
  

解决方案

在我使用SHA1在PHP和C＃和C＃输出字母均大写字母，PHP是小写。

我会建议使用C＃和PHP中相同的编码（UTF8和UTF16都是不错的选择）

在C＃中的选择：

• Encoding.ASCII。 GetBytes会


• Encoding.UTF8.GetBytes


• ...

编码PHP：

• 的 mb_convert_encoding

I'm trying to convert this function into PHP but somehow it does not give same results.

public static string EncodePassword(string pass, string salt) {
    byte[] bytes = Encoding.Unicode.GetBytes(pass);
    byte[] src = Convert.FromBase64String(salt);
    byte[] dst = new byte[src.Length + bytes.Length];
    byte[] inArray = null;
    Buffer.BlockCopy(src, 0, dst, 0, src.Length);
    Buffer.BlockCopy(bytes, 0, dst, src.Length, bytes.Length);
    HashAlgorithm algorithm = HashAlgorithm.Create("SHA1");
    inArray = algorithm.ComputeHash(dst);
    return Convert.ToBase64String(inArray);
}

This is my take on that in PHP

function CreatePasswordHash($password, $salt) {
    $salted_password = base64_decode($salt).$password;
    $result = hash('SHA1',$salted_password,true);
    return base64_encode($result);
}

And of course it does not work. So what am I doing wrong here?

These are the values for testing:

$salt         = 'Xh2pHwDv3VEUQCvz5qOm7w==';
$hashed_value = '0U/kYMz3yCXLsw/r9kocT5zf0cc=';
$password     = 'Welcome1!';

if ($hashed_value === CreatePasswordHash($password,$salt)) {
  echo "Good job!";
}

Edit: Working solution based on suggestions from Martyx and Slacks

function CreatePasswordHash($password, $salt) {
    $upass = mb_convert_encoding($password,'UCS-2LE','auto');
    $salted_password = base64_decode($salt).$upass;
    $result = hash('SHA1',$salted_password,true);
    return base64_encode($result);
}

解决方案

Once I used SHA1 in PHP and C# and in C# output letters were in uppercase and in PHP it was in lowercase.

I would recommend to use the same encoding in C# and in PHP (UTF8 and UTF16 are good choices).

Choices in C#:

• Encoding.ASCII.GetBytes
• Encoding.UTF8.GetBytes
• ...

encoding PHP:

• mb_convert_encoding
