DES完整的加解密算法,使用C语言实现,经过测试,可以运行。
明文分组长64比特。有效主密钥长56比特,根据密钥生成算法,由主密钥生成16个48比特的子密钥。
该算法共16轮,每轮使用一个子密钥。
在进行16轮加密之前,先对明文做一个初始置换IP。
每一轮加密的轮函数f为: .
在16轮加密之后,对比特串L16R16换位为R16 L16,做逆置换IP-1,从而得到密文C。

置换密码亦称换位密码。置换只不过是一个简单的换位。每个置换都可以用一个置换矩阵 来表示。每个置换都有一个与之对应的逆置换 。置换密码的特点是仅有一个发送方和接收方知道的加密置换(用于加密)和对应的逆置换(用于解密)。它是对明文 长字母组中的字母位置进行重新排列,而每个字母本身并不改变。-Password replacement, also known as transposition cipher. Replacement is just a simple transposition. Each

In cryptography, a transposition cipher is a method of encryption by which the positions held by units of plaintext (which are commonly characters or groups of characters) are shifted according to a regular system, so that the ciphertext constitutes

置换密码算法的原理是不改变明文字符,只将字符在明文中的排列顺序改变,从而实现明文信息的加密。置换密码也叫换位密码。
试编程实现矩阵换位密码。它的加密方法是将明文中的字母按照给定的顺序安排在一个矩阵中,然后用根据密钥提供的顺序重新组合矩阵中的字母,形成密文。例如,明文为attack begins at five,密钥为cipher,将明文按照每行6个字母的形式排在矩阵中,如下形式:
a t t a c k
b e g i n s
a t f i v e
根据密钥ciphe
