VIM encryption function

-The advantages of VIM's encryption function

1. After encryption, if you do not know the password, you will not see the plaintext, including the root user can not see

-Cons

1. Obviously let others know encryption, it is easy for others to destroy the encrypted files, including content destruction and deletion;

-Encryption Test

```

[Email protected] shell]# vim Jiami.txt

Jaogj

Chy

Jaogaowe

Jaoghwq

Jaog

(The above content is only test content)

: X (note here is the uppercase X) carriage return;

Enter Password: ************ (enter after you can see the need for password)

Please enter again: ************

Then save and exit

[[email protected] shell]# cat Jiami.txt (after viewing is garbled

vimcrypt~01! O_. 4x¤:a

```

= = with cat or more to view the contents of the file, displayed as garbled, with Vim to re-edit the file, will prompt for a password, if the password entered is incorrect, the same will be displayed as garbled!

Note: Do not forget the password after the file is encrypted! ==

-If the password is set, but there is a problem we set the password how to cancel the password? Here's how vim cancels the password

1. First method:: Set key=

```

Jaogaowe

Jaoghwq

Jaog

: Set key=

Use VIM to open the file, such as Jiami.txt, to enter the correct password, and then at the time of editing, set the password to NULL, the command is: set key=

[email protected] shell]# cat Jiami.txt

Johagowhoag

Jaogj

Chy

Jaogaowe

Jaoghwq

Jaog

```

2.

```

Johagowhoag

Jaogj

Chy

Jaogaowe

Jaoghwq

Jaog

: X after the direct return, enter after the direct use of the password can be saved to exit

[email protected] shell]# cat Jiami.txt

Johagowhoag

Jaogj

Chy

Jaogaowe

Jaoghwq

Jaog

```

Warm hint: The configuration file encryption, the program again to call the encrypted file is not possible.
