Abstract
A file sharing method and apparatus. The method includes uploading, by a first terminal, each encrypted file to a server for saving, and receiving a uniform resource locator (URL) that is returned by the server and corresponds to a location for saving each encrypted file, generating a key package that includes a shared key and a URL that correspond to a file to be shared, and providing the key package for a second terminal, so that the second terminal acquires a corresponding encrypted file by using the URL in the key package, and decrypts the acquired encrypted file by using the shared key in the key package.
