图中加密应用程序的实现

ieee一种基于混沌的新加密方法An Image Encryption Scheme Based on Chaotic Map - In this paper, a novel block digital image encryp- tion scheme based on a chaotic coupled map lattices (CML) is reported. Within this scheme, an original image is decomposed into sub-blocks with a given size, and an external secret key with 192-bit is used and mapped to the system parameters, which are employed to generate a spatiotemporal chaotic binary sequence matrix to encrypt the block original image. Besides, the former sub-block encrypted result will be acted as a feedback to the following sub-block encryption proc- ess. The proposed scheme is described in detail, along with the security analyses such as key space analysis, sensitivity analysis, information entropy analysis and correlation coefficients analysis of adjacent pixels. The computer simulation results indicate that the suggested image encryption scheme has some properties desir- able in a good security

MD5加密算法源代码,个人感觉相当有学习的热的价值,希望大家共同学习,共同进步.-MD5 encryption algorithm source code, personal feeling quite hot the value of learning, I hope everyone learn together and seek common progress.

汇编程序写的Hash校检程序，分享源码，支持SHA1和MD5两种，支持拉拽，支持剪切板的复制和比对，有进行条，自动计算耗时 （使用了不太精确的计时器），速度还是可以的，大概就这样。
