MD5 Introduction
MD5 's full name, Message-digest algorithm 5, was developed by the MIT Computer Science Lab and RSA Data Security Inc in the early 90, through MD2, MD3 and MD4.
Message-digest refers to the hash transformation of a byte string (message), which transforms a byte string of any length into a long, large integer. Note that I use the word "byte string" instead of "string" because the transformation is only related to the value of the byte,

Before using Raidtools, it is important to know whether the core currently in use supports MD. If you're using 2.0.X at the core, and you're not compiling it yourself, in most cases, soft raid is supported. If you are unsure, you should compile the core yourself. When configured, you should select support for Md. After determining which core support raid is being used, compile the Raidtools package as follows:
$cd raidtools-0.41 $./configure $make $make install ##make

MD5 (Message-digestalgorithm 5) is one of the most widely used hashing algorithms in computers. It can be used to convert data into a fixed set of values , the predecessor of which is mainly MD2, MD3 and MD4 algorithms. The MD2 algorithm was developed by Rivest in 1989 and was later discovered by Rogier and Chauvaud if the checksum was ignored and the MD2 generated a conflict. In order to enhance the security of the algorithm, Rivest in 1990 to develo
