Abstract
A person-to-person secure file transfer system includes an originating computer that receives a public key of a recipient from a cloud computing system. The originating computer encrypts a file using a message key, and encrypts the message key using the public key of the recipient. The encrypted file is stored in the cloud computing system. In response to a request from a receiving computer, the cloud computing system decrypts the encrypted message key using a private key of the recipient, decrypts the encrypted file using the message key, and provides the now decrypted file to the receiving computer. In another example, the cloud computing system provides the private key of the recipient and the encrypted file to the receiving computer, which decrypts the encrypted message key using the private key of the recipient and decrypts the encrypted file using the message key.
