# whspbrd

Simple end-to-end encrypted terminal chat with a relay server.

## Build

```bash
go build -o whspbrd
```

## Server

```bash
./whspbrd --mode server --listen :9090
```

## Client

First run once to print your identity (share with others):

```bash
./whspbrd --mode client --show-identity
```

Then connect (you need the peer fingerprint and base64 public key):

```bash
./whspbrd --mode client --connect 127.0.0.1:9090 --peer <peer-fingerprint> --peer-key <base64-pubkey>

## TUI

```bash
./whspbrd --mode client --tui --connect 127.0.0.1:9090
```

TUI commands:

- `/add <name> <pubkey>` add a contact.
- `/rename <name|fingerprint> <new-name>` rename contact.
- `/remove <name|fingerprint>` remove contact.
- `/trust <pubkey>` trust a peer key.
- `/sendfile <path>` send a file.
- `/whoami` show your fingerprint.
- `/pubkey` show your public key.
- `/help` list commands.

TUI navigation:

- `Tab` switch focus between Users and Input.
- `Enter` send message.
- `Up/Down` select contact in Users.
- `PgUp/PgDn` scroll chat history.
- `Ctrl+U` / `Ctrl+D` page up/down.
- `Home` / `End` jump to top/bottom of chat.

## Self-test

```bash
./whspbrd --selftest
```
```

During chat, commands:

- `/whoami` shows your fingerprint.
- `/pubkey` shows your base64 public key.
- `/trust <base64-pubkey>` stores a peer key (TOFU).
- `/sendfile <path>` sends a file (images supported).
- `/quit` exits.
- `/list` shows last 50 messages (stored locally).
