Generate a random password in PHP
Posted by MB in Uncategorized on March 22, 2011
Here’s a code snippet that will quickly generate a random password, using PHP. You can specify the characters set and the number of characters.
function generatePassword($length = 6, $chars = '23456789abcdefghijkmnpqrstuvwxyzABCDEFGHIJKMNPQRSTUVWXYZ')
{
$password = '';
$char_length = strlen($chars);
for ($i = 0; $i < $length; $i++)
{
$num = rand() % $char_length;
$password .= $chars[$num];
}
return $password;
}
Comments are welcome, as always. Have a faster way or a leaner function? Feel free to share!
Enabling and disabling the Administrator account in Windows 7
Posted by MB in Uncategorized on March 22, 2011
Windows 7, like Windows XP and Vista, has a built-in administrator account. This can be used for system recovery, resolving permissions issues, and logging in when a user’s profile is corrupt, among other things.
However, in Windows 7 the administrator account is disabled by default. This is actually a good thing, as XP had it enabled by default with no password — not very secure.
So how do you enable the administrator account?
Via command line:
At an administrator-level command prompt, enter the following command:
net user administrator /active:yes
This enables the administrator account. To disable it, simply do:
net user administrator /active:no
You can also set the administrator password by typing:
net user administrator __password__
substituting your desired password for __password__.
That’s it.
