Hello. There is a function

function generate_password($length=8) { $keychars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_:;"; $randkey=""; $max=strlen($keychars)-1; for($i=0;$i<=$length;$i++) $randkey.=$keychars{rand(0,$max)}; return $randkey; }

Suppose we have generated a password, something like "vlMqooJ", or "vlMqooJ" (at the end of the space). Further one more function

 function htmlspecialchars_decode_php4($str, $quote_style = ENT_COMPAT) { return strtr($str, array_flip(get_html_translation_table(HTML_SPECIALCHARS, $quote_style))); }

and from the above password, you can get the encrypted password "c684f43dc0c37b8d0fd58f5270929a016ead9ade"

Please explain how to get the above encrypted password using the above password?

  • I will say this: it is likely that this is SHA1 from the password with salt. - Nofate ♦

Get the password and encrypt it the way you want!

Option one, no more.

you can take md5 ();

hash guess function

if you guess, then you can also great-great-great-great-grandchildren podnapryach.
