Generate new randomness r for payload, distinct from amount #179

Open Slixe opened 6 months ago

Slixe commented 6 months ago

Description

This PR is made to fix the privacy issue which allow to brute force and de-anonymize a TX.

What I'm doing is:

Generate a new randomness named R
Encrypt it using public keys from sender & receiver, and include it as overhead in the payload
Generate a shared key from RG (r * G)
Encrypt / Decrypt using the shared key
Define a new RPC Type to handle it
add test for encrypt/decrypt using new method
support new format in daemon_communication.go

Fixes # (issue) Fix the issue #178
