There are no central servers and all traffic is peer to peer by default (routed via Tor or I2P). -User IDs are simply Tor onion service/I2P host id + PGP fingerprint. -Clients consolidate feeds from peers into 1 “timeline” using RSS format. -Private messages are only accessible by the intended peer based on the PGP id. -Onionr is not intended to be a replacement for Ricochet, OnionShare, or Briar. -All traffic is over onion/I2P because if only some was, then that would make that traffic inherently suspicious. +User IDs are simply Tor onion service/I2P host id + Ed25519 key fingerprint. +Private blocks are only able to be read by the intended peer. +All traffic is over Tor/I2P, connecting only to Tor onion and I2P hidden services. + ## Goals: - • Selective sharing of information with friends & public + • Selective sharing of information • Secure & semi-anonymous direct messaging • Forward secrecy • Defense in depth - • Data should be secure for years to come, quantum safe (though not necessarily every “layer”) + • Data should be secure for years to come • Decentralization * Avoid browser-based exploits that plague similar software * Avoid timing attacks & unexpected metadata leaks -## Assumptions: - • Tor & I2P’s transport protocols & AES-256 are not broken, sha3-512 2nd preimage attacks will remain infeasible indefinitely - • All traffic is logged indefinitely by powerful adversaries + ## Protocol -Clients MUST use HTTP(s) to communicate with one another to maintain compatibility cross platform. HTTPS is recommended, but HTTP is acceptable because Tor & I2P provide transport layer security. + +Onionr nodes use HTTP (over Tor/I2P) to exchange keys, metadata, and blocks. Blocks are identified by their sha3_256 hash. Nodes sync a table of blocks hashes and attempt to download blocks they do not yet have from random peers. + +Blocks may be encrypted using Curve25519. + ## Connections - When a node first comes online, it attempts to bootstrap using a default list provided by a client. - When two peers connect, they exchange PGP public keys and then generate a shared AES-SHA3-512 HMAC token. These keys are stored in a peer database until expiry. - HMAC tokens are regenerated either every X many communications with a peer or every X minutes. Every 10MB or every 2 hours is a recommended default. - All valid requests with HMAC should be recorded until used HMAC's expiry to prevent replay attacks. - Peer Types - * Friends: - * Encrypted ‘friends only’ posts to one another - * Usually less strict rate & storage limits - * OPTIONALLY sign one another’s keys. Users may not want to do this in order to avoid exposing their entire friends list. - • Strangers: - * Used for storage of encrypted or public information - * Can only read public posts - * Usually stricter rate & storage limits -## Data Storage/Delivery - Posts (public or friends only) are stored across the network. - Private messages SHOULD be delivered directly if both peers are online, otherwise stored in the network. - Data SHOULD be stored in an entirely encrypted state when a client is offline, including metadata. Data SHOULD be stored in a minimal size with garbage data to ensure some level of plausible deniablity. - Data SHOULD be stored as long as the node’s user prefers and only erased once disk quota is reached due to new data. - Posts - Posts can contain text and images. All posts MUST be time stamped. - Images SHOULD not be displayed by non-friends by default, to prevent unwanted viewing of offensive material & to reduce attack surface. - All received posts must be verified to be stored and/or displayed to the user. +When a node first comes online, it attempts to bootstrap using a default list provided by a client. +When two peers connect, they exchange Ed25519 keys (if applicable) then Salsa20 keys. - All data being transfered MUST be encrypted to the end node receiving the data, then the data MUST be encrypted the node(s) transporting/storing the data, +Salsa20 keys are regenerated either every X many communications with a peer or every X minutes. - Posts have two settings: - • Friends only: - ◦ Posts MUST be encrypted to all trusted peers via AES256-HMAC-SHA256 and PGP signed (signed before encryption) and time stamped to prevent replaying.

A temporary EdDSA key for use in every message is exchanged every X many configured messages (or posts), for use in addition with PGP and the HMAC. - When both peers are online messages SHOULD be dispatched directly between peers. - All messages must be verified prior to being displayed. +All valid requests with HMAC should be recorded until used HMAC's expiry to prevent replay attacks. +Peer Types + * Friends: + * Encrypted ‘friends only’ posts to one another + * Usually less strict rate & storage limits + * Strangers: + * Used for storage of encrypted or public information + * Can only read public posts + * Usually stricter rate & storage limits - Clients SHOULD allow configurable message padding. ## Spam mitigation To send or receive data, a node can optionally request that the other node generate a hash that when in hexadecimal representation contains a random string at a random location in the string. Clients will configure what difficulty to request, and what difficulty is acceptable for themselves to perform. Difficulty should correlate with recent network & disk usage and data size. Friends can be configured to have less strict (to non existent) limits, separately from strangers.
