Key Generator
=============

[](#key-generator)

Generates RSA key pairs for Keboola services — currently used for Snowflake key-pair authentication of Connection workspaces (see [`keboola/staging-provider`](../staging-provider)).

Requires `ext-openssl`.

Installation
------------

[](#installation)

```
composer require keboola/key-generator
```

Usage
-----

[](#usage)

```
use Keboola\KeyGenerator\PemKeyCertificateGenerator;

$generator = new PemKeyCertificateGenerator();

// Unencrypted private key
$pair = $generator->createPemKeyCertificate(null);

// Private key encrypted with a passphrase
$pair = $generator->createPemKeyCertificate('my-passphrase');

$pair->privateKey; // PEM-encoded 2048-bit RSA private key
$pair->publicKey;  // PEM-encoded public key
```

`createPemKeyCertificate()` returns a `PemKeyCertificatePair` with exactly two values — despite the name, **no certificate is returned**. Internally it also builds a certificate signing request from `CertificateSigningRequest::createDefault()` (hard-coded Keboola company details) and self-signs it, but that certificate is currently discarded. Exposing it would require changing the return type and making the CSR subject caller-supplied.

The generated key pair is not persisted anywhere; storing it is the caller's responsibility. `PemKeyCertificatePair::$privateKey` and the `$password` argument are marked `#[SensitiveParameter]` so they are redacted from stack traces.

Failures at any OpenSSL step throw a `RuntimeException`.

Development
-----------

[](#development)

Run everything through the library's Docker Compose service:

```
docker compose run --rm dev-key-generator composer install
docker compose run --rm dev-key-generator composer ci   # validate + phpcs + phpstan + tests
```

No environment variables are required.
