Elgamal数字签名的一个大体验证,用于对一个文件的签名后在进行认证.一个VC开发的小程序.(Elgamal digital signature verification of a general for the signature of a document during the certification after. A small VC development process.)

看到RSA加密的C++类下载的人不少，我也下载了，并且稍微改动了一下，使它看上去更加易懂。在新年随手写了一套RSA文件加密，用win32dll封装使用了这个类，用C#写了文件加密和操作界面，可以实现密钥的保存和对任何文件的RSA加密操作。送给大家祝大家新年快乐。(see RSA encryption C downloaded to many people, I have downloaded and slightly altered a bit it looks more comprehensible. New Year threw in a written document RSA encryption, win32dll Compliant with the use of this category, C# to write document encryption and interface, can achieve key to the preservation of any documents and the RSA encryption operation. Give you wish you a happy New Year.)

逆向工程揭秘，包含大量加密解密详细说明。学习逆向工程必备(The secret of Reverse engineering The detailed description contains a large number of encryption and decryption. To learn reverse engineering necessary)

实现维吉尼亚密码，用键盘接收明文和密钥，屏幕打印密文和解密后的明文。 可以实现：大小写敏感，明文小写则密文大写，明文大写则密文小写输出，注意输入的健壮性控制，明文字符超出字符集后保留原文(Virginia to achieve the password, use the keyboard to receive the plaintext and the key, the screen printing ciphertext and the decrypted plaintext. Can be achieved: case sensitive, then the ciphertext plaintext lowercase uppercase, lowercase plaintext ciphertext output is capital, pay attention to the robustness of the control input, plaintext characters out retain the original character set)

信息加密原码，用md5算法实现，开发语言：c(original message encryption code used md5 algorithm, the development of language : c)

3des加密解密,des加密解密该算法通过编译，可以直接使用。(3DES encryption and decryption algorithms.)

通过C语言实现的AES CMAC加密和解密算法。上传文件为完整的VC6工程目录。AES加密算法即密码学中的高级加密标准（Advanced Encryption Standard，AES），又称Rijndael加密法，是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES，已经被多方分析且广为全世界所使用。经过五年的甄选流程，高级加密标准由美国国家标准与技术研究院 （NIST）于2001年11月26日发布于FIPS PUB 197，并在2002年5月26日成为有效的标准。AES 算法基于排列和置换运算。排列是对数据重新进行安排，置换是将一个数据单元替换为另一个。AES 使用几种不同的方法来执行排列和置换运算。 AES 是一个迭代的、对称密钥分组的密码，它可以使用128、192 和 256 位密钥，并且用 128 位（16字节）分组加密和解密数据。与公共密钥密码使用密钥对不同，对称密钥密码使用相同的密钥加密和解密数据。通过分组密码返回的加密数据的位数与输入数据相同。迭代加密使用一个循环结构，在该循环中重复置换和替换输入数据。(AES CMAC encryption and decryption algorithm C language. VC6 upload files to complete the project directory . AES encryption algorithm that is Cryptography Advanced Encryption Standard (Advanced Encryption Standard, AES), also known as Rijndael encryption method, a block encryption standard adopted by the U.S. federal government . This standard is used to replace the original DES, has been widely analyzed and multi used around the world . After five years of the selection process , the Advanced Encryption Standard by the American National Institute of Standards and Technology (NIST) on November 26, 2001 Posted in FIPS PUB 197, and May 26, 2002 became effective standards . AES algorithm based on permutation and substitution operations. Data re- arrangement is arranged , is replaced with a replacement unit of data to another . AES using several different methods to perform alignment and replacement operations. AES is an iterative , symmetric key block password , it can use 128, 192, and )
