# Parsec Tool

This repository contains a tool to communicate with the [Parsec
service](https://github.com/parallaxsecond/parsec) on the command-line.

## Getting started

To compile and list the available commands:

```
$ cargo build
$ cargo run
```

Ping the service:

```
$ cargo run -- ping
```

## Modifying Parsec service endpoint

For demos and to test the Parsec service, you might want to change the Parsec endpoint location. For
that, set the `PARSEC_SERVICE_ENDPOINT` environment variable to correction endpoint.

To set a Unix Domain Socket Listener endpoint at `/tmp/parsec.sock`:

```
$ export PARSEC_SERVICE_ENDPOINT=unix:/tmp/parsec.sock
```

## Modifying logging output

You can set the `RUST_LOG` environment variable to modify the logging outpout. See [the
documentation](https://docs.rs/env_logger/0.8.3/env_logger/index.html) for more information.

## Data format

Unless specified otherwise below, the data format expected by the commands is the same as describe
in the [Parsec
Book](https://parallaxsecond.github.io/parsec-book/parsec_client/operations/index.html). The
`--help` option of commands might give more information about the expected format.

- ECDSA signatures are formatted using the ASN.1 representation `Ecdsa-Sig-Value` described in [RFC
   3279](https://tools.ietf.org/html/rfc3279#section-2.2.3).
- Plaintext data is expected/shown as a UTF-8 string (input data of `sign`, output data of
   `decrypt`).
- Ciphertext data is expected/shown as base 64 (output data of `sign`, input data of `decrypt`).
- Exported public keys are encoded in PEM. By default PKCS#8 format
  is used for RSA [RFC 3279](https://datatracker.ietf.org/doc/html/rfc3279#section-2.3.1)
  and ECC [RFC 5480](https://datatracker.ietf.org/doc/html/rfc5480#section-2)
  public keys. With `--pkcs1` parameter RSA keys exported in PKCS#1 format
  [RFC 2313](https://datatracker.ietf.org/doc/html/rfc2313#section-7.1).

## SPIFFE based authenticator

To be able to authenticate with the [JWT-SVID
authenticator](https://parallaxsecond.github.io/parsec-book/parsec_service/authenticators.html#jwt-spiffe-verifiable-identity-document-authenticator),
compile this crate with the `spiffe-auth` feature.

# Demo
