# The Manual

## Architecture

* gui
* four internal mircoservers (auth, contact, market and message)
* core code module and lmdb
* one external i2p hidden service
* jwt for internal auth, jwp for external

### JWP (JSON Web Proof)

* utilizes some external blockchain (neveko uses monero) for authorization of auth tokens
* 32 byte random signing keys generated on app start-up
* `Hmac<Sha384>` internal, `Hmac<Sha512>` external (jwp)
* see [proof.rs](../neveko-core/src/proof.rs)

* contents be decoded by 3rd parties but only the owner of the signing key can finalize the validation
* should be kept secret

## Getting started

### Adding a contact

* go to `AddressBook` in the gui
* enter .b32.i2p address of contact and click add
* if all goes well you will have imported their public neveko gpg app key
* dont reuse the app gpg keys anywhere else!
* don't forget to trust the contact with `sign key` in the `check status` window

### Create JWP

![create_jwp](../assets/create_jwp.png)

* getting started the app will automatically generate an account and associated monero PRIMARY address. Only use it here to maintain privacy
* deposit some stagenet monero in your xmr account (address in Wallet tab under `Show QR`)
* once unlocked neveko xmr balance will display
* click `check status` and `Create JWP`
* when authorizing to send to contact an invoice will be generated
* authorize payment and tx proof generation in the prompt
* this tx proof will be used to create an encrypted json web proof of payment with each contact
* think of it as a reusable, unforgeable coupon or ticket
* the invoice shows payment per blocks (time)
* default is 1 piconero per day
* the jwp is cached by the client until block time expiration at which time you will be required to authorize another payment

## Sending a message

* the `check status` button will show current jwp for each contact
* `clear stale jwp` will purge data in case of timeout issues
* don't keep large amounts in neveko just enough for fees and jwps
* once a valid jwp is created (takes a few minutes) the `compose` button will be visible
* you need to click `check status` on contacts before sending to refresh jwp expiration check
* draft a plain text message, dont be shy
* verify recipient (.b32.i2p address) and press `send`
* plain text messages never leave your machine
* you can click `Refresh` button in the Mailbox to check for new messages
* messages must be decrypted by clicking `decrypt`

### fts (failed-to-send)

* messages are automatically rebroadcasted every minute until either the contact
  comes back online or the JWP expires.
* If contacts don't come back online before JWP expiration the message must be drafted again
* It is primarily meant for handling connectivity issues or the edge case where a contact is
  is online during the `check status` but goes offline while the message is being drafted
