我用 Java 制作的应用程序使用 Whirlpool 来散列密码。现在我需要对 PHP 使用相同的方法。这是我用 Java 编写的代码:
private String getPasswordHash(String user, String password)
{
String salt = "M0z3ah4SKieNwBboZ94URhIdDbgTNT";
String user_lowercase = user.toLowerCase();
// mix the user with the salt to create a unique salt
String uniqueSalt = "";
for(int i = 0; i < user_lowercase.length(); i++)
{
uniqueSalt += user_lowercase.substring(i, i + 1) + salt.substring(i, i + 1);
// last iteration, add remaining salt to the end
if(i == user_lowercase.length() - 1)
uniqueSalt += salt.substring(i + 1);
}
Whirlpool hasher = new Whirlpool();
hasher.NESSIEinit();
// add plaintext password with salt to hasher
hasher.NESSIEadd(password + uniqueSalt);
// create array to hold the hashed bytes
byte[] hashed = new byte[64];
// run the hash
hasher.NESSIEfinalize(hashed);
// turn the byte array into a hexstring
char[] val = new char[2 * hashed.length];
String hex = "0123456789ABCDEF";
for(int i = 0; i < hashed.length; i++)
{
int b = hashed[i] & 0xff;
val[2 * i] = hex.charAt(b >>> 4);
val[2 * i + 1] = hex.charAt(b & 15);
}
return String.valueOf(val);
}
但现在我需要将此代码“翻译”为 PHP。这是我试图做的,但我不是使用 PHP 的专家:
$salt = "M0z3ah4SKieNwBboZ94URhIdDbgTNT";
$user = "Speedys";
$password = "test123";
//This is what the final result should look like:
$result = "8BD01A206E7B5378B00F77A0E3C5C39B7011CCF87F5BE132F495A77F418E0743C6CB514D53EF01CD4A2C170013C8B9C76E03D9CC94BA404983375CBC3E67E703";
$user_lowercase = strtolower($user);
$uniqueSalt = "";
for($i = 0; $i < strlen($user_lowercase); $i++)
{
$uniqueSalt .= substr($user_lowercase, $i, $i + 1) . substr($salt, $i, $i + 1);
// last iteration, add remaining salt to the end
if($i == strlen($user_lowercase) - 1)
$uniqueSalt .= substr($salt, $i + 1);
}
$hash = hash( 'whirlpool', $password.$uniqueSalt );
但我没有得到相同的结果。请你帮助我好吗?
编辑:这是我使用实际 php 代码得到的结果:

这是我使用 Java 得到的结果以及我想要的结果:
