A petite library of essential encryption functions for PHP 7.1+. For legacy PHP version support, look [here](https://github.com/mmeyer2k/dcrypt/blob/master/docs/LEGACY.md).

Install
=======

[](#install)

Add dcrypt to your composer.json file requirements. Don't worry, dcrypt does not have any dependencies of its own.

```
composer require "mmeyer2k/dcrypt:^13.2"
```

Block Ciphers
-------------

[](#block-ciphers)

The dcrypt library helps application developers avoid common mistakes in crypto implementations that leave data at risk.

[Specification document](https://github.com/mmeyer2k/dcrypt/blob/master/docs/CRYPTO.md)

### Keys

[](#keys)

Safe usage of dcrypt's block cipher functions requires the use of a high entropy 256 bit (minimum) key. Keys should be passed into dcrypt in *base64* encoded format. **You are responsible for the randomness of your key!**

Generate a new key on the linux CLI:

```
head -c 32 /dev/urandom | base64 -w 0 | xargs echo
```

Or with PHP...

```
