# ETSI GS QKD 014 client command-line program and library for Rust and C

[![DOI](https://data.4tu.nl/v3/datasets/3618fc0a-6b89-46c3-8199-5cf5bdb46a29/doi-badge.svg)](https://doi.org/10.4121/3618fc0a-6b89-46c3-8199-5cf5bdb46a29)

Quantum Key Distribution (QKD) hardware provides cryptographic keys that can be used to secure confidential data. This software allows to request keys exchanged using QKD from QKD hardware or a Key Management System by following the ETSI GS QKD 014 standard. It is then up to the user of this library to use these keys to encrypt data. There are 3 ways to use the client: as a command-line program, as a Rust crate or as a C library.

## Dependencies

Install [Rust](https://www.rust-lang.org/tools/install).
Then install libsodium:

```bash
sudo apt install libsodium-dev
```

## Command-line program

### Installation

```bash
cd binary
cargo install --path .
```

### Usage

Retrieving KME status:

```bash
$ etsi014-cli --host kms.example.org --port 443 --key client-1.key --cert client-1.crt --server-ca server-ca.crt --target-sae-id client-2 status
source_KME_ID=kms-1.example.org
target_KME_ID=kms-2.example.org
source_SAE_ID=client-1
target_SAE_ID=client-2
key_size=256
...
```

Requesting new keys:

```
$ etsi014-cli --host kms.example.org --port 443 --key client-1.key --cert client-1.crt --server-ca /usr/share/ca-certificates/mozilla/ISRG_Root_X1.crt --target-sae-id client-2 get-keys --amount 3 --key-size 256

```

Requesting keys by UUID:

```bash
$ etsi014-cli --host kms.example.org --port 443 --key client-2.key --cert client-2.crt --server-ca /usr/share/ca-certificates/mozilla/ISRG_Root_X1.crt --target-sae-id client-1 get-keys-by-ids --ids=851884a2-57c3-4b83-876e-6de27882d003,16771d3f-994b-4850-aa5e-86138544a4a6,b81bfeec-c35f-45e1-a394-361da46f3dcb
