Abstract
A method relates to receiving, by a processing device, a first request to decrypt encrypted data stored on an encrypted portion of a drive, transmitting, to a decryption server, a second request comprising an encrypted first encryption key, wherein the encrypted first encryption key is produced by encrypting a first encryption key using a public key of an asymmetric key pair, receiving the first encryption key from the decryption server, decrypting an encrypted second encryption key using the first encryption key to produce a second encryption key, and decrypting the encrypted data using the second encryption key to produce data.
