Abstract
A computer-implemented method for securing data at third-party storage services may include (1) receiving, at a server-side computing system, a request to provide a user with access to a file that is encrypted, (2) determining, in response to the request, whether a transitory symmetric key of the user is available to encrypt a decryption key with which the file may be decrypted, (3) encrypting the decryption key with the transitory symmetric key of the user if the transitory symmetric key of the user is available or encrypting the decryption key with the public key of an asymmetric key pair designated for the user if the transitory symmetric key of the user is unavailable, and (4) storing the encrypted decryption key. Various other methods, systems, and computer-readable media are also disclosed.
