Abstract: Disclosed are mechanisms that enable secure file sharing between applications using an operating system framework. In some examples, an extension map is received by a client device. The extension map relates a file extension to an alias file extension. A management software development kit (SDK) is used by an application. The management SDK identifies that the application originates a file comprising the file extension, stores the file as an extension-aliased file by changing its file extension to the alias file extension according to the extension map. The extension-aliased file is transferred to a recipient application using a file sharing utility of an operating system of the client device.

Abstract: Disclosed are various embodiments for cryptographic processing on client devices. A cryptographic service can receive a cryptographic operation request from a client application. The cryptographic operation request can include a key identifier for a private key and data to be cryptographically processed and the cryptographic operation request specifying a cryptographic operation to be performed. A cryptographic provider can then be identified based at least in part on the key identifier for the private key. A request is subsequently sent to the cryptographic provider to perform the cryptographic operation on the data using the private key. A response is then received from the cryptographic provider and sent to the client application.
