在使用vi或者vim编辑文件是，在存盘退出的时候，应该使用:wq或者:x退出，但是有时候可能不小心按了:X，这时体统会提示：Enter encryption key:
如果你没有仔细看提示，比如继续输入:x，Enter encryption key: *Enter same key again: *
那么实际上就给这个文件加密了，下次打开就会要求你输入密键，例如:[oracle@ts01 admin]$ vim $ORACLE_HOME/sqlplus/admin/glogin.sql
Enter encryption key: *

[oracle@ts01 admin]$
否则就显示乱码。
要接触密码，步骤如下:vim fileEnter encryption key: 输入密码:set key= :w!
例如：[oracle@ts01 admin]$ vim $ORACLE_HOME/sqlplus/admin/glogin.sql
Enter encryption key: * 输入密码
。。。。。。。。文件正文原文
:set key= :w! 存盘
现在这个密码的口令限制就解除了，呵呵。
