Can I echo password from mysql if so how do I do this as I done <?php echo $password; ?> but it blank


Thank you for replys

[dan-dan]

What code do you have so far?

[mlseim]

It's probably encrypted?
But as Dan-Dan mentioned ... let's see the script so far.

[Whatnot]

yes the password is encrypted can it be done?

[mlseim]

This is a better explanation that I can provide:

.

[Whatnot]

so can I decipher the password then echo it?

[Keleth]

If its encrypted? Not really... some encryptions have been broken, like MD5, but if an encryption was easy to reverse engineer, it'd serve no purpose.

[dan-dan]

No you can't! MD5 hashing is a one way encryption. That is why to match a password typed by a user to a password saved in the database, the typed password would also be hashed first.

[Fou-Lu]

Encrypted: yes, you sure can. If you know how it was generated you can reverse it.
Hashed: no. Its purpose is one way, although you may be able to calculate an equivalency phrase (ie: more than one value hash to the same result).

MD5 (don't use btw), sha, and many others are all hashing techniques. You cannot go backwards. Well designed salting techniques would also make creating a comparable phrase through brute a horrendously long task to calculate. As in years, if you're lucky (or by theory, best case scenario would be O(1), but good luck at that).

You never compare the value of a database stored password. You compare the same hashed or encrypted value of a provided one to the database for comparison.

Thanks for the lingo correction Fou, I always got those confused.

[Whatnot]

         if($database->addNewUser($subemail, md5($subpass), $subuser, $subgender, $subage)){

that hash?

[Keleth]

Yes, MD5 is a hash, as Fou mentioned. So you can't get back the original password, it would defeat the entire purpose of password security.
