Hai semua, saya punya masalah dengan password yang di enkrip,
ceritanya saya buat form member dengan password yang di enkrip, syntax nya sbb :

<?php

// input username baru
// input password baru ($passAsli)

$pengacak = "AJWKXLAJSCLWLW";
$passEnkrip = md5($pengacak . md5($passAsli) . $pengacak );

/* procedure simpan data username
dan password $passEnkrip ke db */

?>

syntax di atas sukses,
yang jadi masalah bagaimana cara mendekrip password tersebut, agar apabila user lupa password dikirimkan email pemberitahuan password dia pas daftar......

bantuin dunk...thanks ya

coba pake fungsi enkripsi AES atau DES, jangan pake MD5.
cara pemanggilan fungsi bisa dilihat di php manual

kalo pake MD5 g bisa dibalikin, mending passwordnya direset aja, terus password yang baru dikirim via email.

fungsi jangan ditaruh di dalam double quote atuh...
dobel quot cuma buat deklarasi string aja...

Code:
<?php $test = "abcd";
echo md5 ($test); ?>

mkhsdnya itu ndak boleh pake double quote kalau nulis echo. karena echo dengan double quote itu hanya ditujukan untuk string/variabel aja.. Jadi misalkan $nama mau diisi dengan PAKDE, maka itu jadinya $nama = "PAKDE"; sedangkan kalau mau panggil fungsi (mis. md5), maka echo md5("xxx"); bukan echo "md5(xxx)";..

klo gak pake md5 gimana pakai base64_encode dan base64_decode ?
bisa juga ditambahin fungsi2 sederhana yang bisa kamu buat.
biar jadinya makin aman.

reset aja passwordnya, kemudian kirimi ke emailnya, sesudah itu insert ke databse dengan mengenkripsi lagi password yang baru tadi direset dgn md5.. :)
