What is Secure Socket Layer And How hackers can use it ?

Some time back you must have heard about hackers hacking into credit card info,password via public computers.so this post is all about it the secured socket layer what is it actually and how it helps in real life or during money paying transaction time...etc.<br /> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj9kS7Ujz_4Jq0gLzCcpnTBL7Ek1LneOCB5CiJrinWGcWxRSSlwZgalnBetVfrcManrJ0UiCkfx5l04kKzuE_vZvc0ABNT3z89XEMh-BtyiTEf-g-4pTAHoZVEeretYJK3STHciaOfKQoyl/s1600/ssl_logo.png" imageanchor="1"><img align="left" alt="secured socket layer" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj9kS7Ujz_4Jq0gLzCcpnTBL7Ek1LneOCB5CiJrinWGcWxRSSlwZgalnBetVfrcManrJ0UiCkfx5l04kKzuE_vZvc0ABNT3z89XEMh-BtyiTEf-g-4pTAHoZVEeretYJK3STHciaOfKQoyl/s320/ssl_logo.png" /></a><br /> A hacker can launch various types of attacks such as Packet sniffing(capturing) or ARP Poisoning to steal your sensitive information.<br /> <br /> Secure Sockets Layer (SSL) is the most widely used technology for creating a secure communication between the web client and the web server. You must be familiar with <b>http://</b> protocol and <b>https://</b> protocol, You might be wondering what they mean. HTTP protocol is used for standard communication between the Web server and the client. HTTPS is used for a secure communication.<br /> <br /> <a href="http://www.darksite.co.in/2012/04/what-cryptography-and-steganography.html">Cryptography Click to Know<br /> </a><br /> <br /> If two users want to have a secure communication they can also use cryptography to accomplish it<br /> <br /> Lets take an example: <br /> <br /> DARKSITE (Decrypt Text) EBSLTJUF (Encrypted Text)<br /> <br /> See the above example i have used simple encryption and decryption Algorithm=+ for the communication and the key is "1", What comes after D is E so as you can see that S is converted into T, What comes After E is F to letter E from the word secure if converted into F and so on, To help you understand this more better I am adding a Video.<br /> <iframe width="550" height="315" src="http://www.youtube.com/embed/5lD8d8scvWo" frameborder="0" allowfullscreen></iframe><br /> So If the hacker starts sniffing from between he will get Encrypted text and as the Hacker does not know the keys so he cant decrypt it, but if the attacker or hacker is sniffing from the starting point so he will get the key and can easily Decrypt the data<br /> <h2><font color="blue"><br /> Standard Communication VS Secure communication</font></h2><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjMHy9p87-_iYHwQZcpsDLGeCYWNOEyUQ4CaxFYzhfWv2CkCnPMvSGS7tosl9_eMcMOeghZv0pGz_sljfyiij1XNBgnuGWDjEGLuoCk-tvvTpIKS45ojnoBZJlAlZ-AMGx5D2mYwr4lU4zn/s1600/secure.jpg" imageanchor="1"><img alt="secured connection" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjMHy9p87-_iYHwQZcpsDLGeCYWNOEyUQ4CaxFYzhfWv2CkCnPMvSGS7tosl9_eMcMOeghZv0pGz_sljfyiij1XNBgnuGWDjEGLuoCk-tvvTpIKS45ojnoBZJlAlZ-AMGx5D2mYwr4lU4zn/s320/secure.jpg" /></a><br /> Suppose there exists two communication parties A (client) and B (server)<br /> <b>Standard communication(HTTP)</b><br /> When A will send information to B it will be in unencrypted manner, this is acceptable if A is not sharing Confidential information, but if A is sending sensitive information say "Password" it will also be in unencrypted form, If a hacker starts sniffing the communication so he will get the password.This scenario is illustrated using the following figure<br /> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjN6r_4pxbmbadQBFXZ44XHMEqrO_0n6VNEUMUSkn_i6jBnd1pmu_QzSjtr8QOUSzGHnI2BTJl-e5s_Oc1tJVxMkdB_EqHTA1zjwWCrE3xoy17524wtDWQEwUgG9ANe7GQp6Vh17eGoCIeC/s1600/http1.jpg" imageanchor="1"><img alt="http connection" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjN6r_4pxbmbadQBFXZ44XHMEqrO_0n6VNEUMUSkn_i6jBnd1pmu_QzSjtr8QOUSzGHnI2BTJl-e5s_Oc1tJVxMkdB_EqHTA1zjwWCrE3xoy17524wtDWQEwUgG9ANe7GQp6Vh17eGoCIeC/s320/http1.jpg" width="550" /></a><br /> <b>Secure communication(HTTPS)</b><br /> In a secure communication i.e. HTTPS the conversation between A and B happens to be in a safe tunnel, The information which a user A sends to B will be in encrypted form so even if a hacker gets unauthorized access to the conversion he will receive the encrypted password (“<b>xz54p6kd</b>“) and not the original password.This scenario is illustrated using the following figure<br /> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhvKqpVT-oGCIfIWhLIibt898kmaYCVF4NCX7Vykr6vhBfs1To0EH__llIsx8ij_7fwU_bGjaDyYR6f6FCw0NNy19Jh-xUbXeBaEyvJwLuS_6hV9ehLTurnjOc5MqqyN9MG2KWkP2qFkEH0/s1600/https1.jpg" imageanchor="1"><img alt="https connection" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhvKqpVT-oGCIfIWhLIibt898kmaYCVF4NCX7Vykr6vhBfs1To0EH__llIsx8ij_7fwU_bGjaDyYR6f6FCw0NNy19Jh-xUbXeBaEyvJwLuS_6hV9ehLTurnjOc5MqqyN9MG2KWkP2qFkEH0/s320/https1.jpg" width="550" /></a><br /> <b>How is HTTPS implemented?</b><br /> <br /> A <b>HTTPS</b> protocol can be implemented by using Secure Sockets Layer (SSL), A website can implement HTTPS by purchasing SSL certificate.<br /> Which websites need SSL Certificate?<br /> The websites where a private conversation is occurred, Websites related to online transactions or other sensitive information needs to be protected needs to SSL Certificate <br /> <br /> <b>How to identify a Secure Connection?</b><br /> <br /> In Internet Explorer and google chrome, you will see a lock icon in the Security Status bar.

Applications of cryptography include ATM cards, computer passwords, and electronic commerce.<br /> <b>Modern cryptography</b><br /> <li>1 Symmetric-key cryptography</li><br /> <br /> <li>2 Public-key cryptography</li><br /> <br /> <li>3 Cryptanalysis</li><br /> <br /> <li>4 Cryptographic primitives</li><br /> <br /> <li>5 Cryptosystems</li><br /> <br /> <br /> <font color="red"><b>Steganography:</b></font>Terrorist Chatting<br /> <br /> Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. The word steganography means "concealed writing" . The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography disguised as a book on magic. Generally, messages will appear to be something else: images, articles, shopping lists, or some other covertext and, classically, the hidden message may be in invisible ink between the visible lines of a private letter.<br /> <br /> The advantage of steganography, over cryptography alone, is that messages do not attract attention to themselves. Plainly visible encrypted messages—no matter how unbreakable will arouse suspicion, and may in themselves be incriminating in countries where encryption is illegal.Therefore, whereas cryptography protects the contents of a message, steganography can be said to protect both messages and communicating parties.<br /> <br /> <b>Different Techniques Used In Steganography</b><br /> 1 Physical<br /> 2 Digital<br /> 3 Network<br /> 4 Printed<br /> 5 Audio<br /> 6 Text<br /> 7 Using Sudoku puzzles<br /> <b><br /> <font color="blue"><br /> Some Best tools</font></b><br /> <b>Hiding Secret Messages in Audio Files</b><br /> <br /> Mp3stegz is an application that apply steganographic (steganography) algorithm in mp3 files.
