文件加密解密

MD5是一种被广泛使用的“消息-摘要算法”。实际上就是一个单项散列函数。(MD5 is a widely used " message- digest algorithm." Is actually a single hash function.)

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.)

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)

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.)

使用DES算法；可以指定使用DES、2DES或者3DES算法；可以对任意的文件进行加密和解密，加密后文件扩展名为.des，可以指定使用ECB,CBC,CFB,OFB,CTR的任意一种模式； (The use of DES algorithm can specify the use of DES, 2DES or 3DES algorithm can arbitrary file encryption and decryption, encryption, named after the file extension. Des, you can specify the use of ECB, CBC, CFB, OFB, CTR arbitrary a model )

c++ 写的加密算法，可以加密解密，采用的算法是比较长用的(c write the encryption algorithm, encryption can be decrypted using the algorithm is relatively long with the)
