php hash

[gsmith]

Is there a version of php and older that doesn't have the hash() function in it?I'm trying to hash passwords using:$pssword=hash('sha1','$_POST["password"]');But it says I'm calling an undefined function when I run it. There's PHP version 4.3.8 on the server I'm working with.

Strange line to put in the documentation for hash(),

(no version information, might be only in CVS)

?might? At least your options have better version info:sha1(), md5()What I can tell you is that I'm using 4.3.7 on XP and md5() and sha1() both work.The hash() does not.You'll want to remove the single quotes : $pssword = sha1('$_POST["password"]');Good Luck,

Ok, I used sha1 as the function instead of hash - and it worked.Now I'm having trouble logging on though. Am I correct that if I sha1() the same word/phrase/etc. I'll get the same hexadecimal output every time? I hope that's correct, because then I'm on the right track...I'm also frustrated becuase I don't understand why what I've done isn't working!

Maybe something about your test of values.You could throw in some 'echo' statements for debuggin'.

<?phpif(isset($_POST['pw'])) {  $user = 'gsmith';  $topsecret = "wwwdot";    if($_POST['user'] == $user && sha1($_POST['pw']) == sha1($topsecret))      echo "passed";      else      echo "failed";}?><form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">    User: <input type="text" name="user" value="gsmith"><br>    Password: <input type="text" name="pw" value="wwwdot"><br>    <input type="submit"></form>

Actually, it turned out to be a slight problem in the file I was storing the usernames and passwords in! Got it solved now though. Thanks for the help!
