US Patent 11784793 Applications in connection with secure encryption

An encryption box device has a memory and a processor coupled to the memory. A first clipboard runs on the processor and downloads a plaintext stream. An encryption engine runs on the processor and receives the plaintext stream and encrypts the plaintext stream to produce an encrypted stream. A digitizer runs on the processor and digitizes the encrypted stream to produce a digitized encrypted stream. A second clipboard runs on the processor and uploads the digitized encrypted stream. The encryption engine may also decrypt the encrypted stream to produce the plaintext stream and upload the plaintext stream to the first clipboard.
