Claim:
1. A computer-implemented method performed in a system comprising a first endpoint, the first endpoint comprising at least one central processing unit, a memory, a storage system and a network interface unit, the system being accessible by a user, the method comprising: a. Generating a message at the first endpoint for sending to a second endpoint, the message comprising a human-readable message body and a message metadata, the message metadata being separate and distinct from the message body, the message metadata comprising a secure channel invitation for the second endpoint to securely communicate with the first endpoint, the secure channel invitation being hidden within the message metadata and does not comprise an instruction to download a communication software; b. Communicating the message from the first endpoint to the second endpoint; c. Receiving a response message, at a first endpoint, from the second endpoint; and d. Establishing the secure communication channel between the first endpoint and the second endpoint based on the received response message, wherein the establishing of the secure communication channel between the first endpoint and the second endpoint comprises performing an encryption key exchange between the first endpoint and the second endpoint, wherein the encryption key exchange between the first endpoint and the second endpoint comprises generating a second message from the first endpoint to the second endpoint, the second message being formatted in accordance with Diffie-Hellman key exchange protocol and sending the second message from the first endpoint to the second endpoint, wherein the encryption key exchange between the first endpoint and the second endpoint is an asymmetric key exchange and wherein the establishing of the secure communication channel between the first endpoint and the second endpoint comprises performing a security association negotiation between the first endpoint and the second endpoint.
