# Getting started

Panda RPKI v0.1.0 is a Linux command-line application. You can use Docker without
installing Rust, or build a native binary. It requires outbound HTTPS to RPKI
repositories, a writable state directory, and enough disk space for repository
objects and outputs. Resource use depends on the selected trust anchors.

## Prepare trust anchors

A trust anchor defines what you trust. Obtain its TAL from the responsible RIR
and obtain the current DER certificate from a certificate URI in that TAL.
Panda RPKI checks that the certificate matches the TAL public key. It takes
both files as explicit inputs; it does not refresh the supplied TA file for you.

For example, the [RIPE NCC trust-anchor page](https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/ripe-ncc-rpki-trust-anchor-structure/)
publishes the RIPE NCC TAL. From the project root:

```bash
mkdir -p input
curl --fail --location --proto '=https' --proto-redir '=https' \
  --connect-timeout 15 --max-time 120 \
  https://tal.rpki.ripe.net/ripe-ncc.tal -o input/anchor.tal
curl --fail --location --proto '=https' --proto-redir '=https' \
  --connect-timeout 15 --max-time 120 \
  https://rpki.ripe.net/ta/ripe-ncc-ta.cer -o input/anchor.cer
```

Check the TAL's current certificate URI before downloading. The
[RIR trust-anchor directory](https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rir-trust-anchor-statistics/)
links the other regional anchors. Use their official TALs and corresponding
certificate locations when preparing a multiple-anchor deployment. Store inputs
outside version control, keep TA certificates current, and retain local policy
files alongside the appropriate TALs. For all five RIRs, use the complete
[five-RIR input guide](trust-anchors.md), including official sources, download
commands, input checks, and the filenames used by Compose.

## Docker first run

Follow the [README Quick start](../README.md#quick-start). It creates
`output/summary.json`, `output/vrps.csv` and `output/result.ccr`. State is retained
under `state/repository-db/`. View warnings in the terminal and inspect the
summary to distinguish rejected objects from successful repository updates.

## Build from source

Install Rust 1.92 or newer. On Debian/Ubuntu, native build dependencies include:

```bash
sudo apt-get update
sudo apt-get install --no-install-recommends build-essential clang libclang-dev \
  pkg-config ca-certificates rsync time
cargo build --locked --release
target/release/panda-rpki --help
```

Run with the same inputs:

```bash
target/release/panda-rpki validate \
  --tal input/anchor.tal --ta input/anchor.cer \
  --rrdp-state-dir state --out output/native \
  --ccr-out output/native/result.ccr
```

For tests, install `python3-cryptography` and `openssl`. See
[Development](development.md) and [Usage](usage.md) for next steps.
