 * Created:  10.01.2009
 *
 * Description:  Modified auth system based on redux_auth with extensive customization. This is basically what Redux Auth 2 should be.
 * Original Author name has been kept but that does not mean that the method has not been modified.
 *
 * Requirements: PHP5.6 or above

| Hash Method (bcrypt or argon2)
| -------------------------------------------------------------------------
| Bcrypt is available in PHP 5.3+
| Argon2 is available in PHP 7.2
|
| Argon2 is recommended by expert (it is actually the winner of the Password Hashing Competition
| for more information see https://password-hashing.net). So if you can (PHP 7.2), go for it.
|
| Bcrypt specific:
| 		bcrypt_default_cost settings:  This defines how strong the encryption will be.
| 		However, higher the cost, longer it will take to hash (CPU usage) So adjust
| 		this based on your server hardware.
|
| 		You can (and should!) benchmark your server. This can be done easily with this little script:
| 		https://gist.github.com/Indigo744/24062e07477e937a279bc97b378c3402
|
| 		With bcrypt, an example hash of "password" is:
| 		$2y$08$200Z6ZZbp3RAEXoaWcMA6uJOFicwNZaqk4oDhqTUiFXFe63MG.Daa
|
|		A specific parameter bcrypt_admin_cost is available for user in admin group.
|		It is recommended to have a stronger hashing for administrators.
|
| Argon2 specific:
| 		argon2_default_params settings:  This is an array containing the options for the Argon2 algorithm.
| 		You can define 3 differents keys:
| 			memory_cost (default 4096 kB)
|				Maximum memory (in kBytes) that may be used to compute the Argon2 hash
|				The spec recommends setting the memory cost to a power of 2.
| 			time_cost (default 2)
|				Number of iterations (used to tune the running time independently of the memory size).
			This defines how strong the encryption will be.
| 			threads (default 2)
|				Number of threads to use for computing the Argon2 hash
|				The spec recommends setting the number of threads to a power of 2.
|
| 		You can (and should!) benchmark your server. This can be done easily with this little script:
| 		https://gist.github.com/Indigo744/e92356282eb808b94d08d9cc6e37884c
|
| 		With argon2, an example hash of "password" is:
| 		$argon2i$v=19$m=1024,t=2,p=2$VEFSSU4wSzh3cllVdE1JZQ$PDeks/7JoKekQrJa9HlfkXIk8dAeZXOzUxLBwNFbZ44
|
|		A specific parameter argon2_admin_params is available for user in admin group.
|		It is recommended to have a stronger hashing for administrators.
