没有个懂c++跟php的吗？求php—>c++

[aladdin_0]

求以下方法的c++版本：
function hash_password($password, $salt = FALSE, $h_byte_size = FALSE)
{
$hash_algos = array(
128 => 'sha512',
64 => 'sha256',
40 => 'sha1',
32 => 'md5'
);
// Even for md5, collisions usually happen above 1024 bits, so
// we artifically limit their password to reasonable size.
if ( ! $password OR strlen($password) > 250)
{
return FALSE;
}

// No hash function specified? Use the best one
// we have access to in this environment.
if ($h_byte_size === FALSE)
{
reset($hash_algos);
$h_byte_size = key($hash_algos);
}
elseif ( ! isset($hash_algos[$h_byte_size]))
{
// What are they feeding us? This can happen if
// they move servers and the new environment is
// less secure. Nothing we can do but fail. Hard.

die('Fatal Error: No matching hash algorithm.');
}

// No salt? (not even blank), we'll regenerate
if ($salt === FALSE)
{
$salt = '';

// The salt should never be displayed, so any
// visible ascii character is fair game.
for ($i = 0; $i< $h_byte_size; $i++)
{
$salt .= chr(mt_rand(33, 126));
}
}
elseif (strlen($salt) !== $h_byte_size)
{
// they passed us a salt that isn't the right length,
// can happen if old code resets a new password
// ignore it
$salt = '';
}

return array(
'salt' => $salt,
'password' => hash($hash_algos[$h_byte_size], $salt.$password)
);

}

了解函数功能，C++重写之

不懂PHP的飘过。。

不要做A语言代码修改为B语言代码的无用功。 也不要做用A语言代码直接调用B语言代码库这样复杂、这样容易出错的傻事。 只需让A、B语言代码的输入输出重定向到文本文件，或修改A、B语言代码让其通过文本文件输入输出。 即可很方便地让A、B两种语言之间协调工作。

PHP语法和C有什么区别，自己写。

我会C++， 也会PHP。 不过你能把分全给我吗？

c++没有提供sha512，sha256，sha1，md5这几个算法直接可用的函数，要转换需要其它库的支持

CryptEncrypt The CryptEncrypt function is used to encrypt data. The algorithm used to encrypt the data is designated by the key held by the CSP module, which is referenced by the hKey parameter. Important changes have been made to the CryptoAPI in order to support S/MIME e-mail interoperability, which affect the handling of enveloped messages. See the Remarks for CryptMsgOpenToEncode for details. Due to French import laws, the Microsoft CSPs do not allow encryption when the Microsoft® Windows NT® operating system is used in France. Therefore, under this condition, this function will fail with the error NTE_PERM. #include <wincrypt.h> BOOL WINAPI CryptEncrypt( HCRYPTKEY hKey, // in HCRYPTHASH hHash, // in BOOL Final, // in DWORD dwFlags, // in BYTE *pbData, // in/out DWORD *pcbData, // in/out DWORD cbBuffer // in ); CryptDecrypt The CryptDecrypt function is used to decrypt data that was previously encrypted by using the CryptEncrypt function.

对于我的项目来说，直接翻译是最简便的方法。
