LM And MD5 Hash Security And Cracking
On this paper I'll talk about Encryption and tips on how to Crack encrypted hashes with out the decryption key. Let’s begin with a proof or the idea behind encryption. Encryption is used to secure or hide data from unauthorized personal and has been around from about 1800 BC and is not going away. There may be all the time going to be a need to safe information and hold it out of unauthorized hands. Now with that said there's at all times going to be new ways to interrupt the encryption and with computers getting faster. Crackers will discover ways to break the encryption faster than ever. We're going to look at encryption algorithms for passwords LM & MD5.
LAN Man Hash (LM)
LAN Man Hash (LM) is a Microsoft Encryption Algorithm used to Encrypt Passwords for Windows NT, 95, 98, ME 2000, XP, and 2003 Server. All although in the latest variations of windows (XP, 2003, Vista) Microsoft has now switched to NTLM for most encryption but LM continues to be widely used. LM is made by taking the users password and converting it to all uppercase and them splitting the password into seven character halves. Each seven character half is transformed to a sixteen bit hash and them each half’s are combined to make a thirty- bit hash witch is the complete LM Hash.
LM Hash Example:
ED39C160E34521DCBF02B3DFE230653A = CERT276ROSENVA
ED39C160E34521DC BF02B3DFE230653A = CERT276 ROSENVA
1st 7 higher Encrypted 2nd 7 Upper encrypted pass
Message Digest Five (MD5)
MD5 hash is a 128-bit (16-byte) hash and are typically represented as 32-digit hexadecimal numbers. The

(Message-Digest algorithm 5) was designed by Ronald Rivest in 1991 and was made to switch old algorithms. At present the MD5 hash is broadly used and for probably the most half is secure. The very best thing to recollect is that with any password it's essential make it complex and long. One of the best passwords are 15 characters or longer containing each upper and decrease case letter with numbers and other particular characters too.
MD5 Hash Example:
16d2c02aad8d116bc403f73454a5eeb1 = emocan

Cracking Password Hashes
Cracking password hashes will be straightforward when you've got time and patience. What I imply by this is that with most basic cracking methods you are running the hash thought a dictionary and hoping the password is in the dictionary you're using. This will take time and you're just shooting the hash into a list. The opposite most common cracking technique is to make use of Burteforce cracking. Burteforce cracking is the means of throwing all possible characters at the password till you discover the match. That is essentially the most time consuming method of cracking and may take years to crack a complex password. The last method we will discus is Rainbow Crack. Rainbow Crack is a Hash cracking utility made by Zhu Shuanglei. Zhu’s Utility relies on Philippe Oechslin's faster time-memory trade-off technique. Rainbow Crack is a pre-compulated Burteforce assault and the assault data is stored in a knowledge base called a rainbow table. With Rainbow Tables it's attainable to crack complex passwords 100’s or 1,000’s of time fast them with a typical Burteforce attack. The downside to rainbow tables is that it takes plenty of time to make the tables sets. On the opposite side of this once a table set is made it may be saved and reused as many time as you need. To make the tables you want rcrak.exe and it's reconvened to have a bunch or massive number of computer systems available to make the tables. There are many places on-line theses days promoting table sets or memberships to used on-line tables submission services.
