software. 2.2 Algorithm principle A brief description of the MD5 algorithm can be: MD5 512-bit grouping to process the input information, and each grouping is divided into 16 32-bit subgroups, after a series of processing, the output of the algorithm is composed of four 32-bit, the four-bit group will be cascaded after this will generate a 32-bit hash value. In the MD5 algorithm, it is necessary to fill the information first, so that the result of

developed a MD2 algorithm in 1989. In this algorithm, the data is first made to complement the information, so that the byte length of the information is 16 multiples. Then, with a 16-bit check and append to the end of the message. And the hash value is computed based on the newly generated information. Later, Rogier and Chauvaud found that if the test was omitted and a MD2 conflict would arise. The MD2 algorithm's encryption results are unique-there is no duplication. In order to enhance the

, calculate the length L to 512 of the take-up operation, and x=l%512, if x is not equal to 448, at the end of the data add a 0, has been circulating until x=448. At this point the length of the data should be 512 N times plus 448, i.e. L ' =512*n+448. The end of the complement. 2) complement the length and the BLOCK:

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 develop the MD4 algorithm, followed by Denboer and

Reproduced, the source is unknown, the article is very good. One. bootloader Introduction Bootloader is the hardware in the power-on, in addition to the BIOS curing program to run the first software, responsible for loading the real operating system, can be understood as a very small OS. Currently in the Linux platform mainly has LILO, grub and so on, in the Windows platform mainly has NTLDR, bootmgr, GRLDR and so on. This describes the startup process of the bootloader based on grub-0.97. Gener

committed.As seen from the diagram, the binary log is logged near the transaction commit, and only one log of the corresponding transaction is included for each transaction, and for the redo log of the InnoDB storage engine, because it records the physical operation log, each transaction corresponds to more than one log entry, and the redo log for the transaction is concurrent, It is not written at the time the transaction commits, so the order in which it is recorded in the file is not the beg

CentOS disk resizing lvm installation Centos LVM space is quickly reduced, and it will not be enough soon. Many people use Gparted resizing, and the command line is not easy to use, the Gparted of the graphic interface cannot be found on CentOS6.4; some people use the Gparted-Live disk, which is very troublesome. In fact, Linux itself provides a powerful and simple resizing tool, which is very easy: 0: current disk status: [root @ CentOS ~] # Df-hFilesystem Size Used Avail Use % Mounted on/dev/m

I'm a complete beginner in assembly and have chosen NASM to work my way up. but I have a problem with the pseudo-instruction set. more precisely, I don't understand how the expressions "$ and $" are used in correlation with times. It's no problem for me to understand what "times" does, but I do not understand the expressions used together with times. Like; Times 512-($-$) db 0 It is expl
