__construct() public
Constructor
-
_configDelete() protected
Delete a single config key
-
_configRead() protected
Read a config variable
-
_configWrite() protected
Write a config variable
-
check() abstract public
Check hash. Generate hash from user provided password string or data array and check against existing hash.
-
config() public
Usage
-
configShallow() public
Merge provided config with existing config. Unlike
config()which does a recursive merge for nested keys, this method does a simple merge. -
hash() abstract public
Generates password hash.
-
needsRehash() public
Returns true if the password need to be rehashed, due to the password being created with anything else than the passwords generated by this class.

check() ¶ abstract public
check(string|array $password, string $hashedPassword): boolCheck hash. Generate hash from user provided password string or data array and check against existing hash.

Returns
boolconfig() ¶ public
config(string|array|null $key = null, mixed|null $value = null, bool $merge = true): mixedUsage
Reading the whole config:
$this->config();Reading a specific value:
$this->config('key');Reading a nested value:
$this->config('some.nested.key');Setting a specific value:
$this->config('key', $value);Setting a nested value:
$this->config('some.nested.key', $value);Updating multiple config settings at the same time:
$this->config(['one' => 'value', 'another' => 'value']);Parameters
-
string|array|null$key optional The key to get/set, or a complete array of configs.
-
mixed|null$value optional The value to set.
-
bool$merge optional Whether to recursively merge or overwrite existing config, defaults to true.
Returns
mixedThrows
Cake\Core\Exception\ExceptionWhen trying to set a key that is invalid.
configShallow() ¶ public
configShallow(string|array $key, mixed|null $value = null): $thisMerge provided config with existing config. Unlike config() which does
a recursive merge for nested keys, this method does a simple merge.
Setting a specific value:
$this->config('key', $value);Setting a nested value:
$this->config('some.nested.key', $value);Updating multiple config settings at the same time:
$this->config(['one' => 'value', 'another' => 'value']);Parameters
-
string|array$key The key to set, or a complete array of configs.
-
mixed|null$value optional The value to set.
Returns
$thishash() ¶ abstract public
hash(string|array $password): stringGenerates password hash.
Parameters
-
string|array$password Plain text password to hash or array of data required to generate password hash.
Returns
stringneedsRehash() ¶ public
needsRehash(string $password): boolReturns true if the password need to be rehashed, due to the password being created with anything else than the passwords generated by this class.
Returns true by default since the only implementation users should rely on is the one provided by default in php 5.5+ or any compatible library
Parameters
-
string$password The password to verify
Returns
bool
