S-DES加密算法输入为一个8位的明文组和一个10位的密钥,输出为8位的密文组,解密算法的输入则是一个8位的密文组和一个10位的密钥,输出位8位的明文组。解密过程是加密的逆。程序使用:读入一个文档文件,对其内容加密,输入密钥和选定存放生成密文的目录,点加密;解密操作与加密相似。-S-DES encryption algorithm for the importation of an eight expressly group and a 10 Key, Output for the eight-man group of close, decryption algorithm input is a secret eight-man group and one of the ten key, Output-8 group of expressly. Encryption and decryption is the inverse. Procedure : Reading into a document file, its content encryption, and the importation of selected key storage generating ciphertext directory, point encryption; Encryption and decryption operations similar.

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.
