Installation

Using Composer

composer require fyre/encryption

In PHP:

use Fyre\Encryption\EncryptionManager;

Basic Usage

• $container is a Container.
• $config is a Config.

$encryptionManager = new EncryptionManager($container, $config);

Default configuration options will be resolved from the "Encryption" key in the Config.

Autoloading

It is recommended to bind the EncryptionManager to the Container as a singleton.

$container->singleton(EncryptionManager::class);

Any dependencies will be injected automatically when loading from the Container.

$encryptionManager = $container->use(EncryptionManager::class);

Methods

Build

Build an Encrypter.

• $options is an array containing configuration options.

$encrypter = $encryptionManager->build($options);

Encrypter dependencies will be resolved automatically from the Container.

Clear

Clear all instances and configs.

$encryptionManager->clear();

Get Config

Get an Encrypter config.

• $key is a string representing the Encrypter key.

$config = $encryptionManager->getConfig($key);

Alternatively, if the $key argument is omitted an array containing all configurations will be returned.

$config = $encryptionManager->getConfig();

Has Config

Determine whether an Encrypter config exists.

• $key is a string representing the Encrypter key, and will default to EncryptionManager::DEFAULT.

$hasConfig = $encryptionManager->hasConfig($key);

Is Loaded

Determine whether an Encrypter instance is loaded.

• $key is a string representing the Encrypter key, and will default to EncryptionManager::DEFAULT.

$isLoaded = $encryptionManager->isLoaded($key);

Set Config

Set the Encrypter config.

• $key is a string representing the Encrypter key.
• $options is an array containing configuration options.

$encryptionManager->setConfig($key, $options);

Unload

Unload an Encrypter.

• $key is a string representing the Encrypter key, and will default to EncryptionManager::DEFAULT.

$encryptionManager->unload($key);

Use

Load a shared Encrypter instance.

• $key is a string representing the Encrypter key, and will default to EncryptionManager::DEFAULT.

$encrypter = $encryptionManager->use($key);

Encrypter dependencies will be resolved automatically from the Container.

Encrypters

You can load a specific encrypter by specifying the className option of the $options variable above.

Custom encrypters can be created by extending \Fyre\Encryption\Encrypter, ensuring all below methods are implemented.

Decrypt

Decrypt data.

• $data is the encrypted data.
• $key is a string representing the encryption key.

$decrypted = $encrypter->decrypt($data, $key);

Encrypt

Encrypt data.

• $data is the data to encrypt.
• $key is a string representing the encryption key.

$encrypted = $encrypter->encrypt($data, $key);

Generate Key

Generate an encryption key.

$key = $encrypter->generateKey();

OpenSSL

The OpenSSL encrypter can be loaded using default configuration using the "openssl" key.

$encrypter = $encryptionManager->use('openssl');

You can also load the OpenSSL encrypter using custom configuration.

• $options is an array containing configuration options.
  • className must be set to \Fyre\Encryption\Handlers\OpenSSLEncrypter::class.
  • cipher is a string representing the cipher, and will default to "AES-256-CTR".
  • digest is a string representing the digest, and will default to "SHA512".

$container->use(Config::class)->set('Encryption.openssl', $options);

Sodium

The Sodium encrypter is the default handler.

$encrypter = $encryptionManager->use();

You can also load the Sodium encrypter using custom configuration.

• $options is an array containing configuration options.
  • className must be set to \Fyre\Encryption\Handlers\SodiumEncrypter::class.
  • blockSize is a number representing the block size, and will default to 16.
  • digest is a string representing the digest, and will default to "SHA512".

$container->use(Config::class)->set('Encryption.default', $options);
