In this paper I will talk about Encryption and easy methods to Crack encrypted hashes without the decryption key. Let’s start with a proof or the thought behind encryption. Encryption is used to secure or disguise knowledge from unauthorized personal and has been around from about 1800 BC and is not going away. There's all the time going to be a have to secure data and preserve it out of unauthorized hands. Now with that said there's at all times going to be new ways to break the encryption and with computer systems getting faster. Crackers will learn how to break the encryption faster than ever. We're going to have a 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, ninety five, 98, ME 2000, XP, and 2003 Server. All though within the latest variations of windows (XP, 2003, Vista) Microsoft has now switched to NTLM for many encryption but LM remains to be widely used. LM is made by taking the users password and converting it to all highercase and them splitting the password into two seven character halves. Every seven character half is converted 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 upper Encrypted 2nd 7 Higher encrypted pass

Message Digest 5 (MD5)

MD5 hash is a 128-bit (sixteen-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 replace old algorithms. At the moment the MD5 hash is widely used and for probably the most part is secure. The very best thing to remember is that with any password it's essential to make it complex and long. The best passwords are 15 characters or longer containing each upper and decrease case letter with numbers and other special characters too.

MD5 Hash Example:

16d2c02aad8d116bc403f73454a5eeb1 = emocan

Cracking Password Hashes

Cracking password hashes will be easy when you have time and patience. What I imply by that is that with most elementary cracking strategies you are running the hash thought a dictionary and hoping the password is within the dictionary you might be using. This may take time and you're md5decrypt just shooting the hash right into a list. The opposite most typical cracking approach is to use Burteforce cracking. Burteforce cracking is the technique of throwing all doable characters on the password till you discover the match. That is the most time consuming methodology of cracking and may take years to crack a fancy password. The last methodology 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 attack and the attack information is stored in an information base called a rainbow table. With Rainbow Tables it is possible to crack complex passwords a hundred’s or 1,000’s of time quick them with a standard Burteforce attack. The downside to rainbow tables is that it takes a whole lot of time to make the tables sets. On the opposite side of this once a table set is made it can be saved and reused as many time as you need. To make the tables you need rcrak.exe and it's reconvened to have a bunch or massive number of computers available to make the tables. There are lots of places online theses days promoting table sets or memberships to used online tables submission services.
