Abstract
An end-to-end mechanism is disclosed herein for transporting encrypted messages over hypertext transport protocol (HTTP) sent to a group of recipients. In particular, the disclosed mechanism receives a message (e.g., as an input from a user) and encrypts that message using an encryption mechanism with a key unique to a particular user and to the message (e.g., different messages are encrypted using different keys). The encrypted message is then stored in a generated object along with other metadata needed for message processing. Once the object is generated, it is signed and encoded into a binary representation that is then sent to a server. The server system receives the binary representation and decodes it back into the object. The metadata of the object is then used to route the message to the correct recipient applications for decryption.
