DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。虽然56位密钥的DES算法已经风光不在,而且常有用Des加密的明文被破译的报道,但是了解一下昔日美国的标准加密算法总是有益的,而且目前DES算法得到了广泛的应用,在某些场合,她仍然发挥着余热.（如：UNIX的密码算法就是以DES算法为基础的）。将其修改为三重DES也能抵抗破解。下面是关于如何实现DES算法的语言性描述：(DES ( Data Encryption Standard ) algorithm, in 1977 the U.S. government s official permission , is a 56 -bit key to encrypt 64 data . 56 keys of the DES algorithm scenery is not , and often with Des encryption expressly decipher reported , but look at the old standard encryption algorithm is always useful , but the DES algorithm has been widely used in a some occasions , she still plays a waste heat . (such as : UNIX password algorithm is DES algorithm -based ) . To modify the Triple DES is also resistant to cracking . The following is a description language on how to achieve the DES algorithm : )

一个袖珍的vc++加密软件，同时还可以解密，加密文件的范围挺大的，几乎所有文件都可以加密，输入密码并解密，好像不是真正意义的加密，只不过是用文件额外加密的方法进行加密，较早时候的程序，不过编译还是顺利的。 (A pocket-sized vc++ encryption software, but also can decrypt encrypted files the scope of getting bigger, almost all the files can be encrypted, enter the password and decrypt the encryption does not seem real, but the file is an additional method of encryption to encrypt Earlier procedures, but the compiler is still smooth.)
