Abstract
Embodiments herein provide, for example, a method that includes generating a deniability key; downloading an encrypted blob from a server, where the encrypted blob includes a server-stored symmetric key and is encrypted with a user password; and decrypted the encrypted blob with a locally-stored symmetric key and the user password, where the sever-stored symmetric key: encrypts a message before transmitting the message to an intended recipient, and decrypts a received message, where the deniability key encrypts a deniable message before transmitting the message to an intended recipient, and where the message and the deniable message are transmitted in a random order to the intended recipient.
