MD5的加密算法！-MD5 encryption algorithm!

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

本文介绍了在JAVA开发环境中如何对文件和数据进行有效的加密，特别是里面API的调用-This paper presents the Java development environment and how to document effective data encryption, in particular inside the API ca

在原作者Jim Gillogly代码的基础上修改优化，并实现C++改写。实现了DES加密。当然，密钥可在源文件中修改，或提供修改的接口函数。-the originator Jim Gillogly code revision on the basis of optimization, and to achieve C rewritten. Implementation of DES encryption. Of course, the key in the source documents changes, or amendments to provide the interface function.

自己做的一个数据加密的程序，程序简单，可以直接使用的。-Their own to do a data encryption procedures, the procedures simple, can be directly used.

个人觉得很不错的简单代码，用很少的程序实现，非常值得一看-in my view, it s a nice and simple code with a few program to achieve the aim. worth to take a look
