A non-transitory computer-readable medium for sharing protected content, comprising instruction stored thereon. When executed on a processor, the instruction performs steps of deriving a shared secret, processing the shared secret using a secure hash algorithm 256 cryptographic hash to produce a primary encryption key, and encrypting a secondary encryption key using the primary encryption key. When the shared secret is derived between a private key and a public key of a first user, encrypting the protected content using the secondary encryption key, and transmitting the encrypted protected content to a server to be accessed by the second user. When the shared secret is derived between the private key of the first user and a public key of a second user, transmitting the secondary encryption key to the second user. The second user uses the secondary encryption key to decrypt the encrypted protected content on the server.

Accelerated encryption and decryption of files with shared secret and method therefor

A non-transitory computer-readable medium comprising a black zone and a plurality of other electronic components for protecting a data exchange from a malicious attack on the data, that when executed on a processor, perform the steps comprising receiving a client hello message from a client, transmitting a server hello message, receiving a pre-master secret message encrypted with a server public key, storing the pre-master secret, protecting the black zone from malicious attacks on data by isolating hardware of the black zone from the plurality of other electronic components, calculating a master secret in the black zone, storing the master secret as a black key in the black zone, receiving a changed cipher specification and finished message encrypted with a session key, and transmitting a finished message encrypted with a symmetric key. The server hello message comprises a certificate.
