Disclosed are methods for encrypting communications with a remote endpoint via a memory device. In one embodiment, a memory device is configured to receive, from the application, a request to establish a communications session with a remote computing device, establish a shared symmetric key, the shared symmetric key shared between the memory device and the remote computing device, receive a message from the application, the message including an identifier of the remote computing device and a payload, generate a ciphertext using the symmetric key and the payload, and return the ciphertext to the application.
