古典密码算法中的单表代换密码算法、移位密码算法、Vigenere密码算法。算法比较简单，用命令的方式。可以随机生成明文和密钥。...

椭圆曲线公钥密码算法,可用于加密和数字签名等应用，该版本算法是有限域GF（p）上的算法-Elliptic curve public key cryptography algorithms can be used for encryption and digital signature applications, the version of the algorithm is a finite field GF (p) the algorithm

VC++实现文件加密功能的源代码，这只是一个简单的例子，如果你感兴趣可以更加深入的研究一下。-VC file encryption function in the source code, this is just a simple example, if you are interested more in-depth study.

其实网上这方面的代码已经不少了,但是大多都如出一辙,主要是给出的代码不但不好理解(主要是为了处理大文件,支持分块,这样就会屑弱初学者对算法的理解),该源代码在引入必要头文件后可以在VC6.0下顺利通过编译-fact that the Internet has been a lot of code, but most of all the same, given the code is not only poor understanding (mainly to handle large files, support block, which would litter beginners weak understanding of the algorithm), the source code necessary to the introduction of the first document in VC6 .0 smoothly through the compiler

数字签名加密算法的两座大厦先后倒塌―MD5和SHA-1这两种应用最为广泛的数字签名加密算法都被山东大学的王小云教授破解。-encrypted digital signature algorithm has two buildings collapsed- MD5 and SHA-1 that the two most widely used digital signature encryption algorithm has been the Shandong University Professor Bruce Schneier break.

et框架由于拥有CLR提供的丰富库支持，只需很少的代码即可实现先前使用C等旧式语言很难实现的加密算法。本类实现一些常用机密算法，供参考。其中MD5算法返回Int的ToString字串。返回数字字母型结果的算法参见之前Blog文章-* This program is free software you can redistribute it and/or modify it * under the terms of the GNU General Public License as published by the * Free Software Foundation either version 2, or (at your option) any * later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

aes加密算法实现，经过FPGA验证的！-aes encryption algorithm, after FPGA validation!

What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over) -What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used (In VB- The same technique can be implemented in

这用于制作 vignere 算法的源代码。它是在密码学中的经典算法之一。使用 visual basic，它将给一个友好的界面给用户和易于使用。享受 ！
