Api Documentation

Stefna\SecretsManager\Manager

Stefna\SecretsManager\Manager->__construct(ProviderInterface $provider)

Pass in your desired provider.

<?php
use Stefna\SecretsManager\Manager;
use Stefna\SecretsManager\Provider\ArrayProvider;

$manager = new Manager(
	ArrayProvider::fromArray([
		'key' => 'value',
		'key2' => new \Stefna\SecretsManager\Values\Secret('key2', ['mixed' => 'value'], ['stage' => 'dev'])
	])
);

You can also chain providers

<?php
use Stefna\SecretsManager\Manager;
use Stefna\SecretsManager\Provider\ArrayProvider;
use Stefna\SecretsManager\Provider\ChainProvider;
use Stefna\SecretsManager\Provider\JsonProvider\JsonProvider;

$defaultSecretsProvider = ArrayProvider::fromArray([
	'key' => 'value',
	'key2' => new \Stefna\SecretsManager\Values\Secret('key2', ['mixed' => 'value'], ['stage' => 'dev'])
]); 

$manager = new Manager(
    new ChainProvider(
        new JsonProvider('secrets.json'),
        $defaultSecretsProvider // if secrets are missing in JsonProvider will fallback to defaultProvider
    )
);

Stefna\SecretsManager\Manager->getSecret(string $key, ?array $options): Secret

Fetches a secret from the configured provider, $key is the name of the secret (or path) you are trying to get.

This will throw a Stefna\SecretsManager\SecretNotFoundException if secret is not found

use Stefna\SecretsManager\Manager;
use Stefna\SecretsManager\Provider\ArrayProvider;
$manager = new Manager(ArrayProvider::fromArray([
	'databases/redis/dsn' => 'redis://localhost:6379',
])); 

$secret = $manager->getSecret('databases/redis/dsn');

$secret->getValue() === 'redis://localhost:6379';

Stefna\SecretsManager\Manager->putSecret(string $key, string|array $value, ?array $options): void

Puts a secret with the given $value, into the storage engine, under the given $key.

If the current adapter doesn't support arrays, and you pass one it, it will throw a Stefna\SecretsManager\ValueNotSupportedException.

Again, some adapters allow passing in custom options to send along with the request.

$manager->putSecret('database/redis', 'postgres://localhost:5432');

And for adapters that support a key/value map as a value:

$manager->putSecret('database/redis', ['dsn' => 'redis://localhost:6379', 'password' => 'my_super_strong_password']);

Stefna\SecretsManager\Manager->deleteSecret(Secret $secret, ?array $options): void

Deletes a secret from the provider using the given $secret.

use Stefna\SecretsManager\Manager;
use Stefna\SecretsManager\Provider\ArrayProvider;
$manager = new Manager(ArrayProvider::fromArray([
	'databases/redis/dsn' => 'redis://localhost:6379',
])); 

$secret = $manager->getSecret('databases/redis/dsn');

$manager->deleteSecret($secret);

Stefna\SecretsManager\Manager->getProvider(): ProviderInterface

Will return provider currently in use

Stefna\SecretsManager\Secret

Secrets are immutable and will throw exception if you try to modify it.

The class implements ArrayAccess to allow ease of reading secrets stored in assoc array.

Stefna\SecretsManager\Secret->getKey(): string

Returns the key for the secret

use Stefna\SecretsManager\Manager;

$manager = new Manager($provider);
$secret = $manager->getSecret('database/redis');

$secret->getKey() === 'database/redis';

Stefna\SecretsManager\Secret->getValue(): string|array<string, mixed>

Returns the value for the secret. If the secret is a key/value map it can be used as an array

use Stefna\SecretsManager\Manager;
use Stefna\SecretsManager\Provider\ArrayProvider;
$manager = new Manager(ArrayProvider::fromArray([
	'databases/redis/dsn' => 'redis://localhost:6379',
])); 
$secret = $manager->getSecret('dabase/redis/dsn');

$secret->getValue() === 'redis://localhost:6379';

Array like access

use Stefna\SecretsManager\Manager;
use Stefna\SecretsManager\Provider\ArrayProvider;
$manager = new Manager(ArrayProvider::fromArray([
	'database' => new \Stefna\SecretsManager\Values\Secret('database', [
		'user' => 'test',
		'name' => 'testDb',
	]),
]));

$secret = $manager->getSecret('database');
$secret['user'] === 'test';
