md5 and base64 encoding

[grenouille]

hi,

i am using an open source (java) filemanager on one of my websites. user data is stored in an xml-file.
when a visitor uses the filemanager itself to register, the password is first md5 encrypted and after that base64 encoded (according to the developer).
now i want to write my own register-form for this filemanager. so i take the password value, md5() and base64_encode() it, but it gives NOT the saùme result as when the filemanager itself encrypts.

f.i password= 19721972  ==> filemanager result = NREVYMjLF45+vX9VM9KAxg==
but : $password=19721972, md5($password) ==> 35111560c8cb178e7ebd7f5533d280c6
  and then base64_encode($password) ==> MzUxMTE1NjBjOGNiMTc4ZTdlYmQ3ZjU1MzNkMjgwYzY=

anyone any idea what may cause this difference? the developer told me he used the Java MessageDigest class
to md5 encrypt.

If you know the answer, please do not get to technical (if possible)  :)

thnx in advance.

I found your problem.


You had
[code]
$password=19721972;
md5($password);
base64_encode($password);

echo $password;
[/code]

What you want is this
[code]
$password = 19721972;
$password = md5($password);
$password = base64_encode($password);

echo $password;
[/code]

okay, my explanation was a bit confusing but that is exactly what i did.

[code]
<?
$str = 19721972;
$str = md5($str);
$str = base64_encode($str);
echo $str;
?>
[/code]

Sorry... my bad

Your developer uses raw md5 output...

this fixes it

[code]
$password = 19721972;
$password = md5($password, true);
$password = base64_encode($password);
[/code]

hm, now i get the following error

Warning: Wrong parameter count for md5() in ...

[code]Note:  The optional raw_output parameter was added in PHP 5.0.0 and defaults to FALSE[/code]

You must have an older version of PHP running.

php version is 4.2.2
could this be the cause of raw output failure?

okay thnx. i'll upgrade first, then i'll annoy you again with my questions :)

I found a solution:

[code]
$password = 19721972;
//$password = md5($password, true);
$password = pack("H*", md5($password));
$password = base64_encode($password);

echo $password;
[/code]

[grenouille]

yep! that's it!

thnx a lot.

grtz
