Multi-party messaging is disclosed. A plurality of public keys is requested by a first device from a server, wherein the plurality of public keys is associated with a plurality of recipients. A message containing one or more components is encrypted using a symmetric key. The symmetric key is encrypted, using each of the respective public keys, resulting in a plurality of encrypted symmetric keys. The encrypted message and the encrypted symmetric keys are encapsulated in an encapsulation. The encapsulation is transmitted to the server.
