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

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
