A cryptography API wrapping the Sodium library, providing a simple object interface for symmetrical and asymmetrical encryption, decryption, digital signing and message authentication.

The `Encryption` class is able to generate secrets and keypairs, encrypt and decrypt data, sign and verify data, and generate and verify digital signatures.

Encrypted messages are returned base64 encoded, while keys and secrets are returned as hexadecimal strings.

The transformation of these to and from binary data makes use of the `sodium_*` timing-safe functions.

All underlying cryptography is performed using the [Sodium](https://www.php.net/manual/en/book.sodium.php) library.

This library requires PHP 7.2 or higher with `libsodium` installed (this is bundled with PHP 7.2 or above, so you probably already have it).

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

Install via Composer

```
composer require dwgebler/encryption
```

Usage
-----
