Most people think that hackers are computer criminals. They fail to recognise the fact that criminals and hackers are two totally different things. Media is responsible for this. Hackers in reality are actually good and extremely intelligent people who by using their knowledge in a constructive manner help organisations, companies, goverment, etc. to secure documents and secret information on the internet.
A white hat is the hero or good guy, especially in computing slang, where it refers to an ethical hacker or penetration tester who focuses on securing and protecting IT systems
An Ethical Hacker is an expert hired by a company to attempt to attack their network and computer system the same way a hacker would. 
Ethical Hackers use the same techniques and tactics as those used by illegal hackers to breach corporate security systems. The end result is the company’s ability to prevent an intrusion before it ever occurs.
The company and the Ethical Hacker enter into a legally binding contract. The contract, sometimes called a “get out of jail free card,” sets forth the parameters of the testing. It’s called the “get out of jail free card” because it’s what harbors the Ethical Hacker from prosecution. Hacking is a felony, and a serious one at that. The terms of the agreement are what transform illegal behavior into a legal and legitimate occupation.
Once the hacker has exhausted his attempts, he reports back to the company with a list of the vulnerabilities he uncovered. The list in and of itself, however, is not particularly useful. What’s most valuable is the instructions for eliminating the vulnerabilities that the Ethical Hacker provides.

In cryptography, MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit hash value. As an Internet standard , MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. However, it has been shown that MD5 is not collision resistant; as such, MD5 is not suitable for applications like SSL certificates or digital signatures that rely on this property. An MD5 hash is typically expressed as a 32-digit hexadecimal number.
MD5 was designed by Ron Rivest in 1991 to replace an earlier hash function, MD4. In 1996, a flaw was found with the design of MD5. While it was not a clearly fatal weakness, cryptographers began recommending the use of other algorithms, such as SHA-1 (which has since been found vulnerable). In 2004, more serious flaws were discovered, making further use of the algorithm for security purposes questionable. In 2007 a group of researchers described how to create a pair of files that share the same MD5 checksum. In an attack on MD5 published in December 2008, a group of researchers used this technique to fake SSL certificate validity.[5][6] US-CERT of the U. S. Department of Homeland Security said MD5 “should be considered cryptographically broken and unsuitable for further use,” and most U.S. government applications will be required to move to the SHA-2 family of hash functions after 2010.
