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...

这是个好东西，可以代替系统的记事本。-This a good thing, the system can replace the notebook.

A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension. Repeated running does the same and removes the "not" from extension. This a "pseudo-encryption", but very useful to avoid automated filtering software. This way it is possible to send "exe" files (or anything else) without the emails being blocked... First - send the source code, have your (enlightened) recipient compile it, then send the "notted" file. The code is not very efficient though, I only had 30 minutes to invest... :)-A simple cpp program, that receives a file, does a bit-wise "not" for every character, and adds "not" to the extension.

这是我用c++实现的一个DES加密算法！应该可以适合那些对加密感兴趣的人看。-This is achieved with c a DES encryption algorithm. Should be suitable for those interested in encryption right people.

AES implementation in C++. Input: key file and the file for encryption Output: the crypted file.

它加密txt文件和cpp文件，并且创建key在你的软盘上，你可以用这个key加密文件.rar-txt file encryption and cpp files and create key in your floppy disk, you can use this document encryption key. Rar

CRC算法与C语言

SHA-1Hash函数源码，可以对任何文件做Hash，得到的Hash值为160位。具有抗强碰撞，弱碰撞等能力。虽然王小云已经找到了个别碰撞。但在新的好的hash函数出来之前仍将被广泛使用。-SHA-1Hash function source, any document can be done right hash, the hash value of 160. Anti-collision, the weak capabilities of the collision. Although Bruce Schneier, had found individual collisions. But the new good hash function will be out before widespread use.

动画介绍aes的详细步骤，生动简单，是很容易理解的动画演示，很好-Animation aes detailed steps, vivid simple and is very easy to understand animation, very good
