+## Options

+### `minStrength`
+
+type: `string` default: `medium`
+
+Sets the minimum strength of the password in entropy bits.
+The entropy is calculated using the formula [here](https://www.pleacher.com/mp/mlessons/algebra/entropy.html).
+
+Available options are:
+
+- `weak` entropy between `64` and `79` bits.
+- `medium` entropy between `80` and `95` bits.
+- `strong` entropy between `96` and `127` bits.
+- `very-strong` entropy greater than `128` bits.

+### `message`

+
+Message that will be shown when the password is not strong enough.

+> An `UnexpectedValueException` will be thrown when the input value is not a `string` or an object implementing `\Stringable`.
+
+## Options
+
+### `pattern`
+
+type: `string` `required`
+
+Regular expression pattern to be matched against.
+
+### `match`
+
+type: `bool` default: `true`
+
+- `true` the validation will pass if the given input value matches the regular expression pattern.
+- `false` the validation will pass if the given input value *does not* match the regular expression pattern. 
+
+### `normalizer`
+
+type: `callable` default: `null`
+
+Allows to define a `callable` that will be applied to the value before checking if it is valid.
+
+For example, use `trim`, or pass your own function, to not evaluate whitespaces at the end of a string:
+
+```php
+// allow all chars except whitespaces
+Validator::length(pattern: '/^\S*$/')->validate('abc '); // false
+
+Validator::length(pattern: '/^\S*$/', normalizer: 'trim')->validate('abc '); // true
+Validator::length(pattern: '/^\S*$/', normalizer: fn($value) => trim($value))->validate('abc '); // true
+```
+
+### `message`
+
+type: `?string` default: `The {{ name }} value is not valid.`
+
+Message that will be shown when the input value does not match the regular expression pattern.
+
+The following parameters are available:
