Subject: Groups - Add X3DH and Double Ratchet mechanisms to PKCS#11 uploaded


Document Name: Add X3DH and Double Ratchet mechanisms to PKCS#11

Description
Extended Triple DH[1], the key-exchange of the Signal protocol, it depends
on XEDDSA since it uses the peers long-term identity keys to both sign and
DH in this protocol.

The Double Ratchet[2] also part of the Signal protocol, this derives keys
at every send/receiving of messages, providing self-healing and forward
secrecy.

i guess i also have to add the footnotes from table 10, to the attributes
of the double ratchet secret key attribute table. but i'm a bit unsure
about all this.
