BCB模式与ECB模式的加密模式与解密模式

输入明文：I do like this book

加密算法E：异或⊕，密钥为cryption；

移位，密钥为5

两种填充模式：（1）0

（2）密文挪用

初始化向量IV：goodluck

用两种模式进行加密，输出相应的密文。

-BCB mode and ECB mode encryption and decryption mode input mode explicitly: I do like this book encryption algorithm E: XOR ⊕, key for cryption　shift, key for 5 to fill the two modes: (1) 0 (2 ) initialization vector misappropriation ciphertext IV: goodluck with two modes for encryption, the output corresponding ciphertext.
