Abstract: The subject technology may be implemented by a device that includes at least one processor configured to encrypt a data object based at least in part on an encryption key. The at least one processor may be further configured to sign the encrypted data object with a private key and transmit the signed encrypted data object to a server for retrieval by another device. The at least one processor may be further configured to generate a sharing object corresponding to the data object, wherein the sharing object includes an encryption key and a public key that corresponds to the private key. The at least one processor may be further configured to encrypt the sharing object using a key of the other device and transmit, over a secure channel, the encrypted sharing object to the other device for subsequent retrieval and verification of the signed data object from the server.
