Base64编码/解码器

IDEA对称算法的软件实现-IDEA symmetric algorithm software

My stuff is aimed at teaching, not efficiency. The others are probably much better implementations. The last one has both C++ and Java versions where my stuff is all C. So lots of choices!

DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。DES算法以被应用于许多需要安全加密的场合。（如：UNIX的密码算法就是以DES算法为基础的）。-DES (Data Encryption Standard) algorithm, in 1977 the United States government"s official permission, is a key 56 to 64-bit data encryption methods. DES algorithm to be applied to many needs security encryption occasions. (Eg : UNIX password algorithm is to DES algorithm-based).

简单的文件加密程序，希望站长保留，一些小课程设计可以用-Simple file encryption program, owners want to retain some small curriculum design can be

TEA加密算法(一个非常短小的加密算法）-TEA encryption algorithm (a very short encryption algorithm)

IDA Pro的中文帮助手册，值得收藏。-IDA Pro Chinese help manual, it is worth Collection
