Hash and encrypt, PHP examples
==============================

Example of an encrypted password hash storage in PHP, uses bcrypt for hashing and AES-128 in CBC mode for encryption. It uses [defuse/php-encryption](https://github.com/defuse/php-encryption) package for crypto operations.
**Do not** encrypt just the passwords, encrypt only password hashes for extra security.

## Usage

- Install [defuse/php-encryption](https://github.com/defuse/php-encryption) via [Composer](https://packagist.org/packages/defuse/php-encryption) first, or at least copy the `Crypto.php` file to your project
- Don't write your own encryption functions

## Key
Generate 128-bit key (in PHP hexdec-chars string) using

- `echo preg_replace('/(..)/', '\x$1', bin2hex(openssl_random_pseudo_bytes(16)));`
- or by running `openssl rand -hex 16 | sed s/\\$..\\$/\\\\x\\1/g` in `bash`

The key should be stored in the following format: `"\xf3\x49\xf9\x4a\x0a\xb2 ..."`. Do NOT encode the `$key` with `bin2hex()` or `base64_encode()` or similar, they may leak the key to the attacker through side channels.
