README

The goal of this module is to create a simple password encryption and verification system.
This module works with two types of algorithms: Bcrypt (default) and ARGON2I/ARGON2ID.

Bcrypt

The Bcrypt algorithm is a hashing algorithm that is widely used and recommended by the security community to store user passwords in a secure way

Bcrypt truncates Input > 72 bytes

The input string of the bcrypt algorithm is limited to 72 bytes. If you use a string with a length more than this limit, bcrypt will consider only the first 72 bytes.

We use a class SamuelPouzet\Crypt\Crypt

Constructor :

$crypt = new Crypt(iterable $options = [], string $algorithm =PASSWORD_DEFAULT)

options :

Bcrypt : cost (number between 4 and 31)

Argon : memory_cost(number), time_cost (number), threads (number)`

**Encode :**

$crypt->hash(string $plaintext): string

**Verify**

$crypt->verify(string $password, string $hash): bool
