vc3004md5算法的研究與實(shí)現(xiàn)-數(shù)據(jù)存儲(chǔ)加密(文件)
【正文】 inly to realize through the algorithm that the encryption of the data is stored. The article is divided into five parts. The first and second parts are describing the current situation and relevant theory knowledge at present of MD5, let us understand the definition of MD5. The focal point is the procedure of MD5 is realized and encapsulation to Dynamic Link Library. In this chapter of encapsulation MD5 class library to Dynamic Link Library, mainly describe why we will select encapsulation Dynamic Link Library for use , and the advantage of encapsulation . Design this of procedure and include reading in the part , revise , insert, delete the realization situations of these functions, and has described the realization course of this four major functions module respectively in way of the flow chart . The last part has shown that the content of system testing and main function of system operate the interface picture .Key words: information security。在 MD5 算法的 DLL 封裝這章，主要是描述我們?yōu)槭裁匆x用封裝 DLL的原因，以及封裝的好處。 該畢業(yè)設(shè)計(jì)是運(yùn)用 microsoft visual c++ 軟件而開發(fā)的，主要是通過算法實(shí)現(xiàn)數(shù)據(jù)的加密存儲(chǔ)。MD5 算法的研究與實(shí)現(xiàn)數(shù)據(jù)存儲(chǔ)加密摘 要隨著網(wǎng)絡(luò)技術(shù)的廣泛應(yīng)用，網(wǎng)絡(luò)信息安全越來越引起人們的重視。它的作用是讓大容量信息在用數(shù)字簽名軟件簽署私人密鑰前被“壓縮”成一種保密的格式，即將一個(gè)任意長度的“字節(jié)串”通過一個(gè)不可逆的字符串變換算法變換成一個(gè)128bit 的串。重點(diǎn)是 MD5 的流程實(shí)現(xiàn)和封裝 DLL。關(guān)鍵詞：信息安全；MD5；加密；封裝 T
