Embodiment one
Message Digest Algorithm MD5 (Chinese Message Digest Algorithm 5 by name) is the widely used a kind of hash function of computer safety field, in order to provide the integrity protection of message.The document number of this algorithm is RFC 1321 (R.Rivest, MIT Laboratory for Computer Science and RSA Data Security Inc.April 1992)
MD5 and Message-Digest Algorithm 5 (Message-Digest Algorithm 5), for guaranteeing that information transmission is unanimously complete.Be one of widely used hash algorithm of computing machine (translating again digest algorithm, hash algorithm), main flow programming language generally existing MD5 realizes.
Be another fixed-length value by data (as Chinese character) computing, be the basic principle of hash algorithm, there are MD2, MD3 and MD4 in the predecessor of MD5.
The effect of MD5 allows Large Copacity information be become a kind of secret form (being exactly the sexadecimal number word string byte serial of a random length being transformed into a fixed length) by " compression " before with digital signature software signature private key.
Typical apply produces informative abstract (Message-Digest) to a segment information (Message), to prevent from being tampered.Such as, have under Unix a lot of software download in have a filename identical, file extent is called the file of .md5, usually only has a line text in this document, general configuration as:
MD5(tanajiya.tar.gz)＝0ca175b9c0f726a831d895e269332461
The digital signature of Here it is tanajiya.tar.gz file.Whole file is used as a Long Binary information by MD5, by its irreversible character string mapping algorithm, creates the MD5 informative abstract that this is unique.In order to have more intuitive understanding to the application of MD5, with an analogy and an example, its course of work once is briefly described below:
People know, on the earth, anyone has oneself unique fingerprint, and this usually becomes juridical authorities and differentiates the most trustworthy method of criminal's identity; Similar with it, MD5 just can produce one same unique " digital finger-print " for any file (regardless of its size, form, quantity), if anyone has done any change to file, namely corresponding " digital finger-print " of its MD5 value all can change.
Usually in certain software information of some software download site, see its MD5 value; its effect is just that we can after this software of download; do a MD5 verification to downloading the special software (as Windows MD5Check etc.) of file of returning, the file provided with the file and this website of guaranteeing acquisition is for identical file.MD5 algorithm is utilized to be widely applied the aspects such as software download website, forum data storehouse, system file security to the scheme of carrying out file verification.
MD5 message digest algorithm: MD5 message digest algorithm is using the information of random length as input value, and " finger print information " or " message digest " value being converted into 128 bit lengths is to represent this input value, and with the value after converting as a result.MD5 algorithm mainly designs for digital signature applications program; In this digital signature applications program, larger file by encryption (ciphering process here by under a cryptographic system [as RSA] public-key cryptography under private cipher key be set complete) before compress in a secure manner.
