How does SysCloud’s Google Drive Encryption application work?

SysCloud’s drive encryption process is given below:

1. Take the source file.
2. Encrypt the file with the AES 256 algorithm.
3. Upload the new file to the Drive with the same title and a “.syscloud” extension.
4. Download the new encrypted file and decrypt to verify if the content is decrypted without corruptions.
5. After verification, remove the source file and retain the new decrypted file.
