加解密現有檔案

1. 建立明文檔 vfile1.yml。

   ceuser@deyu:~/ansible_pb$ echo 'vault file 1' > vfile1.yml
   
   ceuser@deyu:~/ansible_pb$ cat vfile1.yml
   vault file 1
   

2. encrypt 加密 vfile1.yml，輸入兩次密碼，成功加密。

   ceuser@deyu:~/ansible_pb$ ansible-vault encrypt vfile1.yml
   New Vault password: 
   Confirm New Vault password: 
   Encryption successful
   

3. 查看加密檔 vfile.yml，是一串亂數。

   ceuser@deyu:~/ansible_pb$ cat vfile1.yml
   $ANSIBLE_VAULT;1.1;AES256
   30346561653064303436343036666238646432303264353035663362666534333839666265613639

   3737
   

4. view 輸入密碼後，才可以檢視加密檔 vfile1.yml。

   ceuser@deyu:~/ansible_pb$ ansible-vault view vfile1.yml
   Vault password: 
   vault file 1
   

5. decrypt 解密 vfile1.yml，輸入密碼，成功解密。

   ceuser@deyu:~/ansible_pb$ ansible-vault decrypt vfile1.yml
   Vault password: 
   Decryption successful
   
   ceuser@deyu:~/ansible_pb$ cat vfile1.yml
   vault file 1
