LM And MD5 Hash Security And Cracking
In this paper I will focus on Encryption and how to Crack encrypted hashes without the decryption key. Let’s begin with an evidence or the idea behind encryption. Encryption is used to safe or hide knowledge from unauthorized personal and has been round from about 1800 BC and is not going away. There may be at all times going to be a need to safe knowledge and preserve it out of unauthorized hands. Now with that stated there is at all times going to be new methods to break the encryption and with computers getting faster. Crackers will discover ways to break the encryption faster than ever. We are 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 versions of home 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 customers password and changing it to all highercase and them splitting the password into seven character halves. Every seven character half is transformed to a sixteen bit hash and them each half’s are mixed to make a thirty-two bit hash witch is the complete LM Hash.
LM Hash Instance:
ED39C160E34521DCBF02B3DFE230653A = CERT276ROSENVA
ED39C160E34521DC BF02B3DFE230653A = CERT276 ROSENVA
1st 7 higher Encrypted 2nd 7 Higher encrypted pass

Message Digest 5 (free md5 decrypter)
MD5 hash is a 128-bit (16-byte) hash and are typically represented as 32-digit hexadecimal numbers. The MD5 (Message-Digest algorithm 5) was designed by Ronald Rivest in 1991 and was made to interchange old algorithms. At present the MD5 hash is widely used and for probably the most part is secure. The best thing to remember is that with any password it's essential make it complex and long. The very best passwords are 15 characters or longer containing both higher and lower case letter with numbers and different special characters too.
MD5 Hash Example:

Cracking Password Hashes
Cracking password hashes might be straightforward if in case you have time and patience. What I imply by this is that with most elementary cracking strategies you're running the hash thought a dictionary and hoping the password is in the dictionary you are using. This can take time and you might be just shooting the hash right into a list. The opposite most typical cracking technique is to use Burteforce cracking. Burteforce cracking is the technique of throwing all possible characters on the password until you find the match. This is the most time consuming method of cracking and can 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 sooner time-memory trade-off technique. Rainbow Crack is a pre-compulated Burteforce assault and the assault data is stored in an information base called a rainbow table. With Rainbow Tables it is potential to crack advanced passwords a hundred’s or 1,000’s of time quick them with an ordinary Burteforce attack. The downside to rainbow tables is that it takes a variety of time to make the tables sets. On the opposite side of this as soon as a table set is made it may be saved and reused as many time as you need. To make the tables you need rcrak.exe and it is reconvened to have a group or massive number of computer systems available to make the tables. There are a lot of places on-line theses days promoting table sets or memberships to used on-line tables submission services.
