c语言编写可对文件加密-c language of the document can be encrypted

DES算法全称为Data Encryption Standard,即数据加密算法,DES算法把64位的明文输入块变为64位的密文输出块,它所使用的密钥也是64位。RSA的安全性依赖于大数分解。公钥和私钥都是两个大素数（ 大于 100个十进制位）的函数。本程序为适合初学者的rsa算法java源码及des源码，开发环境eclipse3.4-DES algorithm called the Data Encryption Standard, that is, data encryption algorithm, DES algorithm to express the 64-bit input block into a 64-bit output ciphertext block, it is also used 64-bit key. RSA" s security depends on the decomposition of large numbers. Public key and private key are two large prime numbers (more than 100 decimal places) of the function. This procedure is suitable for beginners of rsa algorithm java source and des-source, development environment eclipse3.4

QCA的OPENSSL模块，支持SSL2、SSL3、TLS等协议，扩展QCA的功能-QCA s OpenSSL module, support SSL2, SSL3, TLS, such as an agreement to expand the functions of QCA

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.
