Impossible. It's a one way encryption. Decryption is not possible.

To encrypt passwords using PHP, e.g. to write them to a database (like if
you're using vpopmail w/ MySQL and want users to change the password from
your web site) you can use the following code:
,-----= [ adopted from vpopmail-source ] =-----
<?php
function randltr() {
$retval = 'a';
$rand = rand() % 64;
if ($rand < 26) $retval = $rand + 'a';
if ($rand > 25) $retval = $rand - 26 + 'A';
if ($rand > 51) $retval = $rand - 52 + '0';
if ($rand == 62) $retval = ';';
if ($rand == 63) $retval = '.';
return($retval);
}
function mkpasswd3(&$clearpass, &$crypted) {
srand ((double)microtime()*1000000);
$salt = '$1$';
for ($i = 0; $i < 5; $i++) $salt .= randltr();
$salt .= '0';
$crypted = crypt($clearpass, $salt);
if (strlen($crypted) > 0) return(true);
return(false);
}
?>
`-----=
and call the functions like in this example:
,-----= [ ] =-----
$clearpass = 'testtest'
$crypted = '';
if (mkpasswd3($clearpass, $crypted)) printf("%s -> %s\n", $clearpass, $crypted);
else echo("Ohoh");
`-----=
To figure out if MD5-support is compiled into your PHP execute this code:
,-----= [ test for MD5 encryption support ] =-----
<?php
printf('CRYPT_MD5: %s%s', CRYPT_MD5, "\n");
?>
`-----=
> i install it with clear password option also.
You won't need to decrypt if clear-password is enabled. The clear password
then will be already present.
But you'll have to remember updating encrypted _AND_ clear password if you
use above PHP functions!!!
