Link Decrypter

golfinhu · April 15, 2012

Hi, i'm trying to make a link decrypter, and i'm having difficulty to decrypt url shorteners such as bit.ly, adf.ly and etc

Using internet explorer i can do, but i wanted to do using _WinHttp functions, because it's more fast!

Anyone can give me an idea how can i do this?

something like:

#include <winhttp.au3>

$hw_open = _WinHttpOpen()
$hw_connect = _WinHttpConnect($hw_open, "http://adf.ly/5XR")
$h_openRequest = _WinHttpSimpleRequest($hw_connect, "POST");...

_WinHttpCloseHandle($h_openRequest)
_WinHttpCloseHandle($hw_connect)
_WinHttpCloseHandle($hw_open)

Thanks a lot.

Example for bit.ly (but adf.ly is similar )

Winhttp.au3 >>

to be honest I checked bugmenot.com for a user (--> chiefpower).

But all you have to do is to create a account, get your personal api key and I guess the rest will be easy...

API KEY --> https://bitly.com/a/your_api_key

but with chiefpower you could give it a try.

#AutoIt3Wrapper_AU3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
#include "WinHttp.au3"
#include <Debug.au3>
Opt("MustDeclareVars", 1)
_DebugSetup (@SCRIPTNAME,false,1,@SCRIPTDIR&""&@ScriptName&".LOG")
;~ provider
global $URL_BASE= "api.bit.ly"
;~ short for www.autoit.com
global $URL_HASH="IfDIRp"

global $BITLY_USER="chiefpower"

global $BITLY_API="R_f4df1a4d776791ac7269ca9970856eca"
; Initialize
Global $hOpen = _WinHttpOpen()
; Specify what to connect to
Global $hConnect = _WinHttpConnect($hOpen,$URL_BASE)
; Create request
Global $hRequest = _WinHttpOpenRequest($hConnect, -1, "v3/expand?login="&$BITLY_USER&"&apiKey="&$BITLY_API&"&hash="&$URL_HASH&"&format=txt")
; Send it
_WinHttpSendRequest($hRequest)
; Wait for the response
_WinHttpReceiveResponse($hRequest)
If @error Then
    _DebugOut("Error ocurred for WinHttpReceiveResponse, Error number is " & @error)
Else
    _DebugOut("Server at '"&$URL_BASE&"' processed the request.")
EndIf

Global $sChunk, $sData
If _WinHttpQueryDataAvailable($hRequest) Then
    ; Read
    While 1
        $sChunk = _WinHttpReadData($hRequest)
        If @error Then ExitLoop
        $sData &= $sChunk
    WEnd
    _DebugOut("THE LONG URL is:#"&$sData&"#" & @CRLF)
Else
    _DebugOut("Site is experiencing problems.")
EndIf
; Close handles
_WinHttpCloseHandle($hRequest)
_WinHttpCloseHandle($hConnect)
_WinHttpCloseHandle($hOpen)

Here is the bitly api complete URL:

for expanding a short url

;~ http://api.bit.ly/v3/expand?login=chiefp...c7269ca9970856eca&hash=IfDIRp

for shorten a real url (you need to add the protocol always ... took me some time to find out :-) )

;~ http://api.bit.ly/v3/shorten?login=chief...longUrl=http://www.autoit.com

Does this help you?

yeah, it's helped a lot!

I'll study the code, and when i finish the decrypter i post here to everyone

thanks a lot for the help!

=D

I found something better

There is a API from http://longurl.org/

call : http://api.longurl.org/v2/services

And you will see all known services ! So this means you only need to implement the longurl api and not all others

The respone you could get in JSON or in XML (I choose JSON, simply because I knew a JSON function (provided by http://www.autoit.de/index.php?page=Thread&postID=220606)

I know there is UDF, but I was to confused to include it ....

The code below is a modfied version of the first one.

I guess you will be fine with that universal API, didn't you?

I'm looking forward to see you code.

I'm looking forward to see you code.

man, this is magic!

What you want to see my code? you did all the work!

all credits are your!

thank you very much, this is a very nice code!

this week i finished everything and post it here =)

I'm a bit late but an easy way for "expand" shortened Urls is to simply ask for his location

#include <WinHttp.au3>

ConsoleWrite ( 'http://ufy.me/09435 : ' & _WinHttpGetUrlLocation ( 'http://ufy.me/09435' ) & @Crlf )

Hi,

Can someone explain to me what a link decrypter is supposed to do? :sweating:

Hi,
Can someone explain to me what a link decrypter is supposed to do?

a link decrypter is supposed to retrieve the real url of an encrypted url like those who are shortened.
