Breaking MD5 hashs

Hello world!

Here is an easy to understand article about breaking md5 hashs. Breaking md5 hashs is a subject really discussed on the Internet. If you are new in the hacking community, the first thing that you learn to do is to break md5 hashs. Actually a lot of developers use the md5 hash function to hash passwords before to store it in a database. So if a hacker is able to compromise a website or a system and he is able to retrieve the hashs, he has to break md5 hashs to recover plaintexts.
To break a md5 hash there are a lot of technics, for example :

• Dictionary attack
• Rainbow table attack
• Brute force attack

For courses I had a challenge where I had to break 5 md5 hashs. So I wanted to write up how I proceeded to break this hashs. In our case, we know that the hashs are randomly generated so it will be difficult to retrieve the plaintext with a dictionary attack. Dictionary attacks are used
when we know that people use common word of the dictionary for their password. We also know that the length of the passwords is between 6 and 10 characters. On the one hand we will see what material I used to break this challenge, on the other hand we will see how I proceeded to recover the plaintexts and then again we will see the good practices to have for a secure password.
