xlProtocol_go
The Go language protocol library for XLattice. The library includes
- tlv16, code supporting the classic Type-Length-Value fields found in many network protocols.
- chunks, a protocol used for intermixing large blocks of raw data with Protocol Buffer messages
- aes_cnx, a protocol for establishing AES communications sessions
aes_cnx
This protocol is used by XLattice nodes for setting up communications sessions with Peers or other XLattice Nodes where the initiating Node knows the public RSA key associated with an address.
- the initiator selects a temporary 256-bit/32-byte AES session key, encrypts it using the respondent’s RSA public key and RSA OAEP, and sends the result to the Peer
- the server chooses the actual 32-byte AES session key, encrypts that using the temporary AES key, and sends this back to the initiator
- the initiator uses the temporary AES key to decrypt the response, and extracts the real AES session key
- the session continues with both sides using the real session key
The Nodes involved, the initiator and the respondent, may use any mutually agreeable protocol to continue the session. That may include a procedure for changing the session key, as is prudent in any longer-term session. It is probably prudent to change the session key at least once an hour if there are significant levels of traffic on the link.
Chunks
Chunks is a message protocol designed to be intermixed with Protobuf (Google’s Protocol Buffer) messages. For more information click here
Project Status
The tlv16, aes_cnx, and chunks packages are stable and well-tested.
The aes_cnx package has been in use since mid-2014 in its present form.
chunks has not yet been used in production.
