elgamal的源程序-ElGamal

汇编内核的MD5算法C源码,核心运算部分采用汇编语言编写，执行高效。VC++环境开发，由于直接在C代码中直接嵌入汇编，因此可无须另外设置，可直接使用。

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.

SHA (安全Hash算法)是一种单向散列算法，可用于数字加密或数字签名，是比MD5更加安全的单向散列算法，与MD5算法一起时被应用最广泛的两种算法。(SHA (secure Hash algorithm) is a one-way hash algorithm, can be used for digital encryption or digital signature is more secure than the MD5 one-way hash algorithm, in conjunction with the MD5 algorithm was the most widely used two algorithms.)

将公钥加密算法RSA应用于小型文件加密。将任意文件加密成文本的解决方案，使其使用更加灵活。-RSA public key encryption algorithm will be applied to small-scale file encryption. Arbitrary file encryption solution into the text to make it more flexible to use.
