Module sphinxcrypto::server

an excerpt from Sphinx Mix Network Cryptographic Packet Format Specification: """ An implementation of the server-side of Sphinx, packet processing. Mix nodes process incoming packets first by performing the Sphinx Packet Unwrap operation to authenticate and decrypt the packet, and if applicable prepare the packet to be forwarded to the next node.

If the Sphinx Packet Unwrap operation returns an error for any given packet, the packet MUST be discarded with no additional processing.

After a packet has been unwrapped successfully, a replay detection tag is checked to ensure that the packet has not been seen before. If the packet is a replay, the packet MUST be discarded with no additional processing.

The routing commands for the current hop are interpreted and executed, and finally the packet is forwarded to the next mix node over the network or presented to the application if the current node is the final recipient. """
