What is Crypt?
In simple words, it's a two-password-protected safe. No one can open it without the key. The password and the salt in the configuration form the key.
Tips
- If you don’t know how to use this encryption/decryption driver, please read this guide carefully
- Please test it locally to understand it fully before use in the production environment.
- The data loss is 100% caused by configuration change. If data has been stored within Crypt, change configuration won't re-encrypt data, those data will be inaccessible to Crypt!
Remind again, please read the document carefully, otherwise the data may be lost！
Instruction
We need to build a new empty folder in the driver (network disk) that has been mounted now.
Then fill in the name of our new empty folder to the Remote path Crypt driver configuration
E.g:
- Our original driving path was
/123, we built a newairempty folder in the '123' directory - Fill
Remote Pathoption inCryptconfig page with/123/air - To encrypt files, you need to upload them to the newly created "Crypt" drive. Encryption will only be applied when files are uploaded to this driver.
- Encrypted files are stored in
remote path, and they can't be opened normally due to the encryption - If you want to open them, you need to view them in the
CryptDriver Folder
- Encrypted files are stored in
Config Example
If you don’t know how to configure, you can use the simpler default configuration as follows. The role of each configuration will be explained in detail below
Please read carefully --- very important
Once the configuration is set and started using, do not modify it, do not modify it, do not modify it!
The original Password and Salt should be kept in other places. These two options will be encrypted and can't be reveled after saving.
- If you forget the password before uploading any file, you can modify and re-fill in the password configuration
If you have not uploaded any file in the Crypt, you may modify the configuration, otherwise do not modify it!!!
If you have data in Crypt, and changed the configuration, Crypt will try to filter out illegal files/folders, but the illegal data still exist in the remote storage
- Illegal means data that is encrypted by another config
Note
There are 5 methods for the encryption combination, (in fact 6 types) Because only the folder encryption is turned on, the file name is not encrypted and the configuration does not take effect (the first one of the example below)
- invalid Filename
Off，Directorytrue - valid Filename
Off，Directoryfalse - valid Filename
Standard，Directoryfalse - valid Filename
Standard，Directorytrue - valid Filename
Obfuscate，Directoryfalse - valid Filename
Obfuscate，Directorytrue
Filename encryption
If you don’t understand, you can use the default configuration
1.The default is
offstate- Whether the file name needs to be encrypted, and the file name is encrypted after uploading
2.Standard Encryption
- Standard encryption safety level high(recommended)
3.Simple Obfuscate
- The security level is very low, but friendly to long file name. Note: for the Chinese file name, special characters will be generated. Some network disk storage may not support them
The left side of the figure below is encrypted Remote path，On the right is the decrypted 'crypt` driver to view the file
- If not enabled Filename encryption，It will be like Upper left corner pic A new encrypted suffix is added behind the source file（xxxxx.xxx .bin ）(The suffix name can be customized)
- If you enabled Filename encryption，It will be like Lower left corner pic In this way, the file name is also confused with encryption, no suffix and the original file name，others can't know what it is, but it can be viewed in
crypt（The folder displayed on the right）
Directory name encryption
default is false, i.e disabled. don't use it if you don't understand below description
When you turn on the folder encryption, you must select a filename encryption type. Otherwise, the folder encryption will not take effect
- The left side of the figure below is encrypted Remote path，On the right is the decrypted 'crypt` driver to view the file
- If disabled Directory encryption，It will be likeUpper left corner pic No change to folder name
- If enabled Directory encryption，It will be displayedLower left corner pic folder name is encrypted
Remote path
It is the storage and encrypted file, which can be any driver in the driver that can be mounted
Password
Just literally meaning password
Salt
It can be treated as the second password if you don't understand it
Encrypted suffix
Advanced options,The default is .bin, the custom must start with ., such as .abc .aaa .Psd.
If the file name is encrypted, the encryption suffix `will not be used
Filename encoding
Advanced options, non -professionals, please do not modify it. The default is base64, but the options other than base64 are not tested. If you encounter problems, you need to solve it yourself.
Advanced usage
Advanced usage is only applicable to those who know about rclone
If you know the rclone very well, you can check 👉 rclone crypt document Currently fully compatible
Note: Alist Crypt used filename_encoding = base64 in default. If you want to use Rclone, please config it in the advanced config. (Reason: more friendly to long filename)
Since Alist does not consider any case-insensitive internally, you may encounter problems when remote storage is case-insensitive. e.g.: use alist local driver on Windows, then use Crypt on it.
