This proposal is about adding a flag to streaming that specifies the type of end-to-end encryption being used.
High-loaded apps can encounter a shortage of ElGamal/AES+SessionTags tags.
Add a new flag somewhere within the streaming protocol. If a packets comes with this flag it means payload is AES encrypted by key from private key and peer's public key. That would allow to eliminated garlic (ElGamal/AES) encryption and shortage of tags problem.
May be set per packet or per stream through SYN.
