The challenge is: aHR0cDovLzQwNDguY28ubmYv

Tips: ba(s(2)-s)e 63+1

To get the password you need to discover what the first line means; the second is 2spooky.

The password is in the form Xxx xxxxxxxxx xxxxxxxx

The password has special letters, but just replace them with normal characters, for example: ç = c, ã = a, etc.

Good luck!

They're closer than you think.

141542 (because of the inurl prefix)

you'll find

http://www.al.sp.gov.br/norma/?id=141542, which shows a law passed in 07/10/2008.

Next,

view the page source and check line 639 (from the insrc prefix above)
