// serverRequest provides functions to create and read server requests
// These are MessagePack encoded requests sent to Seekia hosts

package serverRequest

// Each encrypted request has a RequestTime and a RequestIdentifier
// RequestTime ensures an attacker cannot replay a request and compare the response size to gain information
// The host will reject any requests with a requestTime that is too old

// RequestIdentifier is random for each request and ensures that the response is intended for the specific request
// Otherwise, a man-in-the-middle attacker could replay old requests created during the same connection, to trick the requestor
// For example, the requestor could make a GetProfilesInfo request, get a response A, and later make a different GetProfilesInfo request
// The attacker could replay response A, and the requestor would wrongly designate the host as malicious (for providing invalid information)
// Request Identifiers prevent this attack

// Acceptable versions is a []int that describes the acceptable versions of profiles/messages/reviews/reports that the requestor can read
// As new versions are created, different hosts and clients will only be able to read certain versions of content
// This list allows hosts and clients who have not upgraded to newer versions to continue serving/downloading content on the network

// See a description of each request and its purpose in Specification.md

//TODO: Add GetFundedStatuses
//	Will be used to get the identity/profile IsFunded statuses from hosts
//	This will lessen the load on the credit account servers
//	We don't need this for messages, because we will always retrieve their fundedStatuses directly from the credits servers
//	Retrieving them from hosts is a privacy risk, and will take too long to retrieve individually
