Abstract
Carrying out, over a network infrastructure, secure execution of cryptographic operations using a public/private key pair is described, wherein the private key is permanently stored on a second computing device that is remote to and accessible to the first computing device through an open network. The method includes establishing a secure connection over the open network between the first computing device and the second computing device, sending a file via the secure connection over the open network to the second computing device and instructing the second computing device to: encrypt or decrypt the file with a private key, of the public/private key pair, that is stored on the second computing device; and send the encrypted or decrypted file to the first computing device via the secure connection over the open network. The encrypted or decrypted file is then received over the open network from the second computing device.
