## commands

## cleanup data

### cleanup for user

To delete all data which isn't necessary for the user:

```bash 
python scripts/main.py --mode cleanup --user "<<user>>"
```

### delete all data

To delete all data execute:

```bash 
python scripts/main.py --mode cleanup
```

### delete decrypted data
To delete all decrypted data execute:

```bash 
python scripts/main.py --mode cleanup --file-types decrypted
```

### delete all encrypted data
To delete all encrypted data execute:

```bash 
python scripts/main.py --mode cleanup --file-types encrypted
```

## decrypt 

### decrypt automatic
To decrypt the data execute:

```bash 
python scripts/main.py --mode decrypt
```

### decrypt accumulated file
To decrypt the accumulated datafile execute:

```bash 
python scripts/main.py --mode decrypt --meta
```


### decrypt defined user
To decrypt the data for a defined user execute:

```bash 
python scripts/main.py --mode decrypt --user "<<user_id>>"
```

### addtional instructions
In the [INSTRUCTIONS.md](./INSTRUCTIONS.md) file the master encrypter can leave additional instructions.

## encrypt

### encrypt main data
```bash 
python scripts/main.py --secret-holders-amount "<<amount>>" --quota "<<quota>>" --mode encrypt --master-password "<<master_password>>" --input-directory "<<input_directory>>"
```

### generate encryption data
To encrypt the master-password file and to create the neccessary encrypted meta data execute: 

```bash 
python scripts/main.py --secret-holders-amount "<<amount>>" --quota "<<quota>>" --mode encrypt --add-user-information --master-password "<<master_password>>" --meta
```

### generate encryption data with user info
To encrypt the master-password file and to create the neccessary encrypted meta data with additional user infos data execute: 

```bash 
python scripts/main.py --secret-holders-amount "3" --quota "50" --mode encrypt --add-user-information --master-password "<<master_password>>" --meta --add-user-information << EOL
