A computer-implemented method for sharing data stored on secure third-party storage platforms may include (1) identifying a request from a client system for a token that provides temporary access to an encrypted file stored under a user account, (2) identifying, in response to the request, an asymmetric key pair designated for the user account that includes an encryption key and a decryption key that has been encrypted with a client-side key, (3) receiving, from the client system, the client-side key, (4) decrypting the decryption key with the client-side key, (5) using the decryption key to generate temporary decryption data that facilitates the decryption of the encrypted file and that is set to expire, (6) generating the token and designating the temporary decryption data as available in exchange for the token, and (7) providing the token to the client system. Various other methods, systems, and computer-readable media are also disclosed.
