在 linux 使用 encfs + fuse 做一個加密檔案系統 filesystem

encfs ~/.crypt 是加密過的部份，目錄結構完全沒變，filename/directory name 經過加密，內容也加密。安全性好像比 loopback 差一點。


與loopback 相比，encfs 的好處是不用先預留空間。 

<hr width="100%" size="2" />

使用你的 package manger, Mandriva 是用 urpmi&nbsp;


#urpmi encfs


我修改過 的 kernel 有出現 DKMS 的 error ， 不用理，只要確定 


modprobe fuse 沒有問題就可以了。


第一次執行&nbsp; /dev/fuse permission/owner 不對 ，這時候


chown xxx /dev/fuse 改成你的 owner


&nbsp;[xxx@www ~]$ encfs ~/.crypt ~/crypt 
The directory &quot;/home/xxx/.crypt/&quot; does not exist. Should it be created? (y,n) y 
The directory &quot;/home/xxx/crypt&quot; does not exist. Should it be created? (y,n) y 
Creating new encrypted volume. 
Please choose from one of the following options: 
&nbsp;enter &quot;x&quot; for expert configuration mode, 
&nbsp;enter &quot;p&quot; for pre-configured paranoia mode, 
&nbsp;anything else, or an empty line will select standard mode. 
?&gt; p 
 
Paranoia configuration selected. 
 
Configuration finished.&nbsp; The filesystem to be created has 
the following properties: 
Filesystem cipher: &quot;ssl/aes&quot;, version 2:1:1 
Filename encoding: &quot;nameio/block&quot;, version 3:0:1 
Key Size: 256 bits 
Block Size: 512 bytes, including 8 byte MAC header 
Each file contains 8 byte header with unique IV data. 
Filenames encoded using IV chaining mode. 
File data IV is chained to filename IV. 
 
..................... 這邊提到 hard link&nbsp; 內定是關閉的 
 
Now you will need to enter a password for your filesystem. 
You will need to remember this password, as there is absolutely 
no recovery mechanism.&nbsp; However, the password can be changed 
later using encfsctl. 
 
New Encfs Password: 
Verify Encfs Password: 


沒有加密的部份就在 ~/crypt &nbsp;


之後的使用還是用


encfs ~/.crypt ~/crypt


這次就只會輸入密碼。&nbsp;


解除掛載用&nbsp;


$ fusermount -u ~/crypt&nbsp;
