# 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.
