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.

DES(Data Encrypton Standard) 算法的实现网上已经有很多，本人在此讲述的是在DES算法加密过程中如何查看16迭代过程中生成的Ki,Li,Ri,Fi,Si等，这样可以当做一个DES加密对照器，这样可以方便的发现你在加密过程中出现的错误! -DES (Data Encrypton Standard) algorithm has been achieved online many, I would like to speak on is the DES encryption algorithm to see how the process 16 iterative process of generating Ki, Li, Ri, Fi, Si, etc., can serve as a control device DES encryption, this can easily find you in the process of encryption the mistakes!
