A secure message is encrypted with a combination of three key 'parts': - A "database key" - to be saved in a database. - A "storage key" - to be stored on a disk/filesystem. - A "verification code" - this code should *not* be stored anywhere. This way, if an attacker has access to the database, it still has only access to a small part of the complete key. The same goes if an attacker has access to the file storage. Even if an attacker has access to the database *and* the file storage, a part of the complete key is still missing. The verification code can be sent (securely) to the receiver of the secure message and with this code, it can decrypt the message and read it. Requirements ------------ [](#requirements) This package requires at least PHP 7.3 with the [sodium](https://www.php.net/manual/en/sodium.installation.php) extension enabled. Install ------- [](#install) Via Composer ``` $ composer require exonet/securemessage ``` Usage ----- [](#usage) ``` // Create the factory. $secureMessageFactory = new Exonet\SecureMessage\Factory(); // Set the (application wide) meta key. $secureMessageFactory->setMetaKey('A_10_random_characters_long_key.'); // Create a new SecureMessage. Note: it is not encrypted yet! $secureMessage = $secureMessageFactory->make('Hello, world!'); // Encrypt the Secure Message. $encryptedMessage = $secureMessage->encrypt(); ``` Please see the `/docs` folder for complete documentation and additional examples.
