Description: des算法源码
DES算法为密码体制中的对称密码体制，又被成为美国数据加密标准，是1972年美国IBM公司研制的对称密码体制加密算法。
其密钥长度为56位，明文按64位进行分组，将分组后的明文组和56位的密钥按位替代或交换的方法形成密文组的加密方法。
DES加密算法特点：分组比较短、密钥太短、密码生命周期短、运算速度较慢。-des algorithm source code for DES algorithm of the symmetric cryptosystem cryptosystem, was to become the United States Data Encryption Standard, is the United States in 1972 developed by IBM Corporation symmetric encryption algorithm cryptosystem. Its key length 56, 64 explicitly grouped according to specific sub-group and after the 56-bit key by an alternative method or exchange group formed ciphertext encryption methods. DES encryption algorithm characteristics: short packet, the key is too short, short life-cycle password, slower speed of operation. Platform: |

Description: DES算法实验报告和代码
1.输入名字，需8个字母，不足的补叉，多余的舍去
2.将字符按ASC2码值转化为二进制，存在数值（指针）中
3.对明文做IP置换（函数）
4.将转换后的数值分成两组，赋给L0,R0，执行下列运算L1—R0,R1-L0.....重复16轮
5.将结果L0R0合并至一个数值，做IP输出-DES algorithm and code an experimental report. Enter the name of eight letters take less than the complement of forks, the extra rounding 2. ASC2 yards according to the value of the character into a binary, there are values (pointer) in 3. Right expressly to do IP replacement (function) 4. will be converted values into two groups, assigned to L0, R0, perform the following operations L1-R0, R1-L0 ..... Repeat 16 5.

Description: 1996年， E.Schaefer 提出了一个简化的DES加密算法， 即S-DES加密算法。S-DES是一个对称分组加密的简化模型，目的不在于应用，它非常具体地说明了分组密码中如何实施扩散和扰乱， 揭示了设计分组密码算法的基本模式和框架，在密码学习中有着重要的意义。编写一个软件能够实现S-DES分组加解密-In 1996, E. Schaefer proposed a simplified DES encryption algorithm, namely, S-DES encryption algorithm. S-DES is a symmetric block cipher of the simplified model, not to application, it is very specifically to understand how to implement block ciphers in the proliferation and disrupted, revealing the design of the basic mode of block cipher algorithms and framework for learning in the password has an important significance. Write a software to achieve S-DES encryption and decryption Packet Platform: |

Description: This particular algorithm is a brute force attack on the popular DES Encryption standard. The DES algorithm consists of 4 main classes which will be briefly discussed
-The first class takes into consideration the assumption that the in the inputs are in hex format. Therefore a method was created to convert the hex into binary so that it could be easily permuted.
-The second class takes the converted binary input and passes it through a variety of member permutation functions.
-The next class also known as the key class handles operations on keys that have not been permuted.
-The S-box functionality is provided by the last class.
