我知道PHP有md5(),sha1()和hash()函数,但是我想使用
MySQL PASSWORD()函数创建一个哈希.到目前为止,我唯一可以想到的只是查询服务器,但是我想要一个功能(最好是在PHP或Perl中),这样一来就可以完成同样的操作,而不需要查询MysqL.
例如：
MysqL哈希 – > 464bb2cb3cf18b66
MysqL5哈希 – > * 01D01F5CA7CA8BA771E03F4AC55EC73C11EFA229
谢谢！
我本来在这个问题上偶然发现我自己寻找一个
PHP实现的两个MysqL密码哈希函数.我无法找到任何实现,所以我自己从MysqL源代码(sql / password.c)修改了自己.以下测试和工作在PHP 5.2：
// The following is free for any use provided credit is given where due.
// This code comes with NO WARRANTY of any kind,including any implied warranty.
/**
* MysqL "OLD_PASSWORD()" AKA MysqL323 HASH FUNCTION
* This is the password hashing function used in MysqL prior to version 4.1.1
* By Rev. Dustin Fineout 10/9/2009 9:12:16 AM
**/
function MysqL_old_password_hash($input,$hex = true)
{
$nr = 1345345333; $add = 7; $nr2 = 0x12345671; $tmp = null;
$inlen = strlen($input);
for ($i = 0; $i < $inlen; $i++) {
$byte = substr($input,$i,1);
if ($byte == ' ' || $byte == "\t") continue;
$tmp = ord($byte);
$nr ^= ((($nr & 63) + $add) * $tmp) + (($nr << 8) & 0xFFFFFFFF);
$nr2 += (($nr2 << 8) & 0xFFFFFFFF) ^ $nr;
$add += $tmp;
}
$out_a = $nr & ((1 << 31) - 1);
$out_b = $nr2 & ((1 << 31) - 1);
$output = sprintf("%08x%08x",$out_a,$out_b);
if ($hex) return $output;
return hex_hash_to_bin($output);
} //END function MysqL_old_password_hash
/**
* MysqL "PASSWORD()" AKA MysqLSHA1 HASH FUNCTION

**/
function MysqL_password_hash($input,$hex = true)
{
$sha1_stage1 = sha1($input,true);
$output = sha1($sha1_stage1,!$hex);
return $output;
} //END function MysqL_password_hash
/**

function hex_hash_to_bin($hex)
{
$bin = "";
$len = strlen($hex);
for ($i = 0; $i < $len; $i += 2) {

$byte_dec = hexdec($byte_hex);

希望别人会发现这个有用的:)
