用密码对表达式进行加密保护

用简单的密码 "Shiver me timbers!" 对一条消息进行加密，因而产生一个 EncryptedObject.

In[1]:=

secretMessage = Encrypt["Shiver me timbers!", "I buried a stash of gold somewhere."]

Out[1]=

数据处于加密状态.

In[2]:=

InputForm[secretMessage]

Out[2]//InputForm=

用同样的密码进行解密.

In[3]:=

Decrypt["Shiver me timbers!", secretMessage]

Out[3]=
