写专属或加密程序。 程序应该采取作为输入由程序然后加密的文件名。 程序应该要求用户输入密钥，应该用于加密文件。 程序的输出应该进入一个文件以同一个文件名，但...

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.

这是一个jsp的的项目。用于支付宝接口开发的MD5加密算法，详细的内容在里面   。

RSA implementation by using Java

应用背景基于java的自定义文件加压解压，拥有比普通压缩包密码更方便更保险的加密程度关键技术通过更改了文件数据写入顺序起到加密效果，如果不用相应的解压程序解压的话会使得文件无法读取
