流密码中RC4算法的加密解密的c程序实现(stream cipher)

sha256计算代码，非常好用的代码，大家可以用这个代码直接计算哈希值，sha256实现 依次执行 SHA256Init、 SHA256Update SHA256Final 三个函数即可得到sha256结果(sha256 sourse code，Is very usefull)

Base64的编码程序 基于VC++编写的(Base64 encoding program written with VC++)

des经典加密算法，实现数据交互过程中的保密(des classical encryption algorithm, data confidentiality during the interaction)

VC++下MD5运行和使用示例,可以正常使用MD5算法(VC MD5)

MD5加密算法，实现报文认证！！运算速度快，兼容性好(MD5 encryption algorithm, message authentication realize! ! Computing speed, better compatibility)

基本古典密码设计——周期为3的多表代替密码的设计和实现(Basic classical cipher design)

100 多个加密和解密可以用到的库, 本人悉心收藏的精品(100 can be used to encrypt and decrypt the library, my collection of boutique carefully)

AES加密以及解密实现，这是一个AES文件加密软件，用VC++ MFC编写，里面有详细的源代码以及加密和解密的具体实现方法。(AES encryption and decryption to achieve, this is a AES file encryption software, written using VC++ MFC, which has detailed source code and encryption and decryption of the specific implementation method.)

整体思路 用createkey.java 文件来产生秘钥，用jiami.java 文件来实 现加密，用jiemi.java 文件来实现解密,用BigInteger.java 来实现 大数的表示及运算，用rsa.java 来实现前端图形界面显示。有关函 数见五个文件里的具体实现。 (The overall outlook createkey.java document used to generate secret keys, used to achieve jiami.java file encryption, used to achieve jiemi.java documents declassified by BigInteger.java to achieve expression of large numbers and calculations, using rsa.java to achieve front-end graphical interface display. Related functions, see the five concrete realization of the document.)
