Encrypting a Local Model File

Log in to the running environment of the encryption/decryption tool as user hwMindX.
Run the following command to create an encryption/decryption working directory, for example, /home/hwMindX/software/infer:
```
mkdir -p /home/hwMindX/software/infer
```

Run the following command to switch to the working directory:

cd /home/hwMindX/software/infer
cp -r ${ResNet-50 model file path}/infer/sdk ./
chmod 500 -R infer

Use the encryption/decryption tool to encrypt the model file.
1. Upload the model file to the directory.
2. Upload the MK.json file to the /home/hwMindX/software directory and run the following command:
```
cd /home/hwMindX/software
chmod 600 MK.json
```
3. Perform encryption.
```
mkdir enc 
chmod 700 enc
aiguard encrypt -i infer -o enc -f MK.json 
chmod 700 -R enc/encrypt
```
  When you run the encryption command, you will be prompted to enter the password for exporting the master key. After you enter the password, an encrypted file is generated and stored in the specified directory /home/hwMindX/software/enc/encrypt/.
  
  MK.json is the file exported in Creating and Exporting a Master Key.
