Abstract
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.
