LZW编码是围绕称为词典的转换表来完成的。这张转换表用来存放称为前缀(Prefix)的字符序列，并且为每个表项分配一个码字(Code word)，或者叫做序号。这张转换表实际上是把8位ASCII字符集进行扩充，增加的符号用来表示在文本或图像中出现的可变长度ASCII字符串。扩充后的代码可用9位、10位、11位、12位甚至更多的位来表示。

IDEA加密算法属于数据块加密算法(Block Cipher)类。IDEA使用长度为128bit的密钥，数据块大小为64bit。-IDEA encryption algorithm is data block encryption algorithm (Cipher Block) category. IDEA use of the length of the 128 bit key, the data block size for 64bit.
