DataBox

1. File encryption

   • AES key is generated locally and uploaded after file encryption. At the same time, the local key will encrypt the AES key again to ensure file security.

   • When downloading the ciphertext, users can use the private key to decrypt the AES key, which will then be used to decrypt the ciphertext.

   • The local key can be exported and reset. After resetting, it failed to open the encrypted file which is uploaded by the original key.

2. File sharing

   • Through the generated URL, users can access, view and download files shared by other users.

   • Through the public Databox, users can directly access, view and download public files through the domain name.
