Systems and methods for securely uploading a data file are presented. A client generates a symmetric encryption key and an initialization vector; encrypts the data file using the symmetric encryption key and the initialization vector; places an upload request with a server to upload the encrypted data file to a first storage device; receives from the server via the communications network, asymmetric encryption components, a signed data file upload URL accessible by the communications network, and a signed key data upload URL accessible by the communications network; encrypts, using the asymmetric encryption components, the symmetric encryption key and the initialization vector, thereby creating encrypted key information; sends, via the signed data file upload URL, the encrypted data file to the first storage device; and sends, via the signed key data upload URL, the encrypted key information to a second storage device.
