The md5sum command is used to generate and verify the MD5 value of the file. It verifies the contents of the file bit by bits, and it is commonly used with checking the integrity of the file.Read the MD5 value of the file[Email protected] ~]# md5sum/

There are a number of Web sites that provide download files while providing the md5sum value of the file. How to check yourself to download the same file as the original file. Use the Md5sum-C option.
The operation is as follows:
1. First create a
md5sum is the command used to compute and verify the MD5 value of a file (the MD5 full name is an algorithm for digest (Message-digest algorithm 5)). It is quite convenient to use, when we download some files from the network, especially the system
The following string is known to be the result of the random number variable md5sum|cut-c 1-8 intercept, please crack these strings corresponding to the md5sum before the random corresponding number?[Email protected] md5]#CatZifuchuang2102929900205d1
When a Linux software is issued, not only a software package but also an authentication is provided to prevent tampering.
The following describes how to generate and verify the md5sum command.

MD5 is the abbreviation of Message-digest algorithm 5 (Information-Digest algorithm), which is widely used in encryption and decryption technology, which can be said to be the "digital fingerprint" of the file. Any file, whether executable, image,

Recently it came to ubuntu12.04 lts release, so I was anxious to download a new version. But in the process, and the vast number of Linux enthusiasts have a lot of communication. and realize that, in fact, before making ubuntu12.04 discs need to do
These two algorithms, can generate a file itself unique (repetition probability tends to infinity) of the signature (32-bit 16 characters), that is, the same content of the file's signature will be the same, so that you can use this signature test,
The MD5 algorithm is often used to verify the integrity of network file transmission and prevent file tampering. MD5Message Digest Algorithm (Message-Digest Algorithm)5), this algorithm computes information of any length by bit, and generates a
