+
+# Documentation
+
+## Requirements
+- PHP 7.4+
+  - `ext-mbstring`
+  - optional:
+    - `ext-json`, `ext-gd`
+    - `ext-imagick` with [ImageMagick](https://imagemagick.org) installed
+    - [`setasign/fpdf`](https://github.com/setasign/fpdf) for the PDF output module
+
+## Installation
+**requires [composer](https://getcomposer.org)**
+
+via terminal: `composer require chillerlan/php-qrcode`
+
+*composer.json*
+```json
+{
+	"require": {
+		"php": "^7.4 || ^8.0",
+		"chillerlan/php-qrcode": "v4.3.x-dev"
+	}
+}
+```
+
+Note: replace `v4.3.x-dev` with a [version constraint](https://getcomposer.org/doc/articles/versions.md#writing-version-constraints), e.g. `^4.3` - see [releases](https://github.com/chillerlan/php-qrcode/releases) for valid versions.
+For PHP version ...
+  - 7.4+ use `^4.3`
+  - 7.2+ use `^3.4.1` (v3.4.1 also supports PHP8)
+  - 7.0+ use `^2.0`
+  - 5.6+ use `^1.0` (please let PHP 5 die!)
+
+In case you want to keep using `v4.3.x-dev`, specify the hash of a commit to avoid running into unforseen issues like so: `v4.3.x-dev#c115f7bc51d466ccb24c544e88329804aad8c2a0`
+
+PSA: [PHP 7.0 - 7.3 are EOL](https://www.php.net/supported-versions.php) and therefore the respective `QRCode` versions are also no longer supported!
+
+## Quickstart
+We want to encode this URI for a mobile authenticator into a QRcode image:
+```php
+$data = 'otpauth://totp/test?secret=B3JX4VCVJDVNXNZ5&issuer=chillerlan.net';
+
+// quick and simple:
+echo '<img src="'.(new QRCode)->render($data).'" alt="QR Code" />';
+```
+
+<p align="center">
+	<img alt="QR codes are awesome!" src="https://raw.githubusercontent.com/chillerlan/php-qrcode/v4.3.x/examples/example_image.png">
+	<img alt="QR codes are awesome!" src="https://raw.githubusercontent.com/chillerlan/php-qrcode/v4.3.x/examples/example_svg.png">
+</p>
+
+Wait, what was that? Please again, slower!
+
+
+## Advanced usage
+
+Ok, step by step. First you'll need a `QRCode` instance, which can be optionally invoked with a `QROptions` (or a [`SettingsContainerInterface`](https://github.com/chillerlan/php-settings-container/blob/master/src/SettingsContainerInterface.php), respectively) object as the only parameter.
+
+```php
+$options = new QROptions([
+	'version'    => 5,
+	'outputType' => QRCode::OUTPUT_MARKUP_SVG,
+	'eccLevel'   => QRCode::ECC_L,
+]);
+
+// invoke a fresh QRCode instance
+$qrcode = new QRCode($options);
+
+// and dump the output
+$qrcode->render($data);
+
+// ...with additional cache file
+$qrcode->render($data, '/path/to/file.svg');
+```
+
+In case you just want the raw QR code matrix, call `QRCode::getMatrix()` - this method is also called internally from `QRCode::render()`. See also [[Custom output interface]].
+
+```php
+$matrix = $qrcode->getMatrix($data);
+
+foreach($matrix->matrix() as $y => $row){
+	foreach($row as $x => $module){
+
+		// get a module's value
+		$value = $module;
+
+		// or via the matrix's getter method
+		$value = $matrix->get($x, $y);
+
+		// boolean check a module
+		if($matrix->check($x, $y)){ // if($module >> 8 > 0)
+			// do stuff, the module is dark
+		}
+		else{
+			// do other stuff, the module is light
+		}
+
+	}
+}
+```
+
+Have a look [in the examples folder](https://github.com/chillerlan/php-qrcode/tree/main/examples) for some more usage examples.
+
+### Notes
+The QR encoder, especially the subroutines for mask pattern testing, can cause high CPU load on increased matrix size.
+You can avoid a part of this load by choosing a fast output module, like `OUTPUT_IMAGE_*` and maybe setting the mask pattern manually (which may result in unreadable QR Codes).
+Oh hey and don't forget to sanitize any user input!
+
+
+## Custom output interface
+
+Instead of bloating your code you can simply create your own output interface by creating a `QROutputInterface` (i.e. extending `QROutputAbstract`).
+
+```php
+class MyCustomOutput extends QROutputAbstract{
+
+	// inherited from QROutputAbstract
+	protected QRMatrix $matrix;   // QRMatrix
+	protected int $moduleCount;   // modules QRMatrix::size()
+	protected QROptions $options; // MyCustomOptions or QROptions
+	protected int $scale;         // scale factor from options
+	protected int $length;        // length of the matrix ($moduleCount * $scale)
+
+	// ...check/set default module values (abstract method, called by the constructor)
+	protected function setModuleValues():void{
+		// $this->moduleValues = ...
+	}
+
+	// QROutputInterface::dump()
+	public function dump(string $file = null):string{
+		$output = '';
+
+		for($row = 0; $row < $this->moduleCount; $row++){
+			for($col = 0; $col < $this->moduleCount; $col++){
+				$output .= (int)$this->matrix->check($col, $row);
+			}
+		}
+
+		return $output;
+	}
+
+}
+```
+For more examples, have a look at the [built-in output modules](https://github.com/chillerlan/php-qrcode/tree/main/src/Output).
+
+In case you need additional settings for your output module, just extend `QROptions`...
+```
+class MyCustomOptions extends QROptions{
+	protected string $myParam = 'defaultValue';
+
+	// ...
+}
+```
+...or use the [`SettingsContainerInterface`](https://github.com/chillerlan/php-settings-container/blob/main/src/SettingsContainerInterface.php), which is the more flexible approach.
+
+```php
+trait MyCustomOptionsTrait{
+	protected string $myParam = 'defaultValue';
+
+	// ...
+}
+```
+set the options:
+```php
+$myOptions = [
+	'version'         => 5,
+	'eccLevel'        => QRCode::ECC_L,
+	'outputType'      => QRCode::OUTPUT_CUSTOM,
+	'outputInterface' => MyCustomOutput::class,
+	// your custom settings
+	'myParam'         => 'whatever value',
+ ];
+
+// extends QROptions
+$myCustomOptions = new MyCustomOptions($myOptions);
+
+// using the SettingsContainerInterface
+$myCustomOptions = new class($myOptions) extends SettingsContainerAbstract{
+	use QROptionsTrait, MyCustomOptionsTrait;
+};
+
+```
+
+You can then call `QRCode` with the custom modules...
+```php
+(new QRCode($myCustomOptions))->render($data);
+```
+...or invoke the `QROutputInterface` manually.
+```php
+$qrOutputInterface = new MyCustomOutput($myCustomOptions, (new QRCode($myCustomOptions))->getMatrix($data));
+
+//dump the output, which is equivalent to QRCode::render()
+$qrOutputInterface->dump();
+```
+
+### Custom module values
+
+You can distinguish between different parts of the matrix, namely the several required patterns from the QR Code specification, and use them in different ways, i.e. to assign different colors for each part of the matrix (see the [image example](https://github.com/chillerlan/php-qrcode/blob/main/examples/image.php)).
+The dark value is the module value (light) shifted by 8 bits to the left: `$value = $M_TYPE << ($bool ? 8 : 0);`, where `$M_TYPE` is one of the `QRMatrix::M_*` constants.
+You can check the value for a type explicitly like...
+```php
+// for true (dark)
+($value >> 8) === $M_TYPE;
+
+// for false (light)
+$value === $M_TYPE;
+```
+...or you can perform a loose check, ignoring the module value
+```php
+// for true
+($value >> 8) > 0;
+
+// for false
+($value >> 8) === 0;
+```
+
+See also `QRMatrix::set()`, `QRMatrix::check()` and [`QRMatrix` constants](#qrmatrix-constants).
+
+To map the values and properly render the modules for the given `QROutputInterface`, it's necessary to overwrite the default values:
+```php
+$options = new QROptions;
+
+// for HTML, SVG and ImageMagick
+$options->moduleValues = [
+	// finder
+	1536 => '#A71111', // dark (true)
+	6    => '#FFBFBF', // light (false)
+	// alignment
+	2560 => '#A70364',
+	10   => '#FFC9C9',
+	// timing
+	3072 => '#98005D',
+	12   => '#FFB8E9',
+	// format
+	3584 => '#003804',
+	14   => '#00FB12',
+	// version
+	4096 => '#650098',
+	16   => '#E0B8FF',
+	// data
+	1024 => '#4A6000',
+	4    => '#ECF9BE',
+	// darkmodule
+	512  => '#080063',
+	// separator
+	8    => '#AFBFBF',
+	// quietzone
+	18   => '#FFFFFF',
+];
+
+// for the image output types
+$options->moduleValues = [
+	512  => [0, 0, 0],
+	// ...
+];
+
+// for string/text output
+$options->moduleValues = [
+	512  => '#',
+	// ...
+];
+```

+## Documentation
+
+### Installation
+**requires [composer](https://getcomposer.org)**
+
+*composer.json* (note: replace `dev-main` with a [version constraint](https://getcomposer.org/doc/articles/versions.md#writing-version-constraints), e.g. `^2.1` - see [releases](https://github.com/chillerlan/php-settings-container/releases) for valid versions)
+```json
+{
+	"require": {
+		"php": "^7.4 || ^8.0",
+		"chillerlan/php-settings-container": "dev-main"
+	}
+}
+```
+
+Profit!
+
+## Usage
+
+The `SettingsContainerInterface` (wrapped in`SettingsContainerAbstract` ) provides plug-in functionality for immutable object properties and adds some fancy, like loading/saving JSON, arrays etc. 
+It takes an `iterable` as the only constructor argument and calls a method with the trait's name on invocation (`MyTrait::MyTrait()`) for each used trait.
+
+### Simple usage
+```php
+class MyContainer extends SettingsContainerAbstract{
+	protected $foo;
+	protected $bar;
+}
+```
+Typed properties in PHP 7.4+:
+```php
+class MyContainer extends SettingsContainerAbstract{
+	protected string $foo;
+	protected string $bar;
+}
+```
+
+```php
+// use it just like a \stdClass
+$container = new MyContainer;
+$container->foo = 'what';
+$container->bar = 'foo';
+
+// which is equivalent to 
+$container = new MyContainer(['bar' => 'foo', 'foo' => 'what']);
+// ...or try
+$container->fromJSON('{"foo": "what", "bar": "foo"}');
+
+
+// fetch all properties as array
+$container->toArray(); // -> ['foo' => 'what', 'bar' => 'foo']
+// or JSON
+$container->toJSON(); // -> {"foo": "what", "bar": "foo"}
+// JSON via JsonSerializable
+$json = json_encode($container); // -> {"foo": "what", "bar": "foo"}
+
+//non-existing properties will be ignored:
+$container->nope = 'what';
+
+var_dump($container->nope); // -> null
+```
+
+### Advanced usage
+```php
+trait SomeOptions{
+	protected $foo;
+	protected $what;
+	
+	// this method will be called in SettingsContainerAbstract::construct()
+	// after the properties have been set
+	protected function SomeOptions(){
+		// just some constructor stuff...
+		$this->foo = strtoupper($this->foo);
+	}
+	
+	// this method will be called from __set() when property $what is set
+	protected function set_what(string $value){
+		$this->what = md5($value);
+	}
+}
+
+trait MoreOptions{
+	protected $bar = 'whatever'; // provide default values
+}
+```
+
+```php
+$commonOptions = [
+	// SomeOptions
+	'foo' => 'whatever', 
+	// MoreOptions
+	'bar' => 'nothing',
+];
+
+// now plug the several library options together to a single object 
+$container = new class ($commonOptions) extends SettingsContainerAbstract{
+	use SomeOptions, MoreOptions;
+};
+
+var_dump($container->foo); // -> WHATEVER (constructor ran strtoupper on the value)
+var_dump($container->bar); // -> nothing
+
+$container->what = 'some value';
+var_dump($container->what); // -> md5 hash of "some value"
+```
+
+### API
+
+#### [`SettingsContainerAbstract`](https://github.com/chillerlan/php-settings-container/blob/main/src/SettingsContainerAbstract.php)
+
+method | return  | info
+-------- | ----  | -----------
+`__construct(iterable $properties = null)` | - | calls `construct()` internally after the properties have been set
+(protected) `construct()` | void | calls a method with trait name as replacement constructor for each used trait
+`__get(string $property)` | mixed | calls `$this->{'get_'.$property}()` if such a method exists
+`__set(string $property, $value)` | void | calls `$this->{'set_'.$property}($value)` if such a method exists
+`__isset(string $property)` | bool | 
+`__unset(string $property)` | void | 
+`__toString()` | string | a JSON string
+`toArray()` | array | 
+`fromIterable(iterable $properties)` | `SettingsContainerInterface` | 
+`toJSON(int $jsonOptions = null)` | string | accepts [JSON options constants](http://php.net/manual/json.constants.php)
+`fromJSON(string $json)` | `SettingsContainerInterface` | 
+`jsonSerialize()` | mixed | implements the [`JsonSerializable`](https://www.php.net/manual/en/jsonserializable.jsonserialize.php) interface
+
+## Disclaimer
+This might be either an utterly genius or completely stupid idea - you decide. However, i like it and it works.
+Also, this is not a dependency injection container. Stop using DI containers FFS.

+# Constant-Time Encoding
+
+[![Build Status](https://github.com/paragonie/constant_time_encoding/actions/workflows/ci.yml/badge.svg)](https://github.com/paragonie/constant_time_encoding/actions)
+[![Latest Stable Version](https://poser.pugx.org/paragonie/constant_time_encoding/v/stable)](https://packagist.org/packages/paragonie/constant_time_encoding)
+[![Latest Unstable Version](https://poser.pugx.org/paragonie/constant_time_encoding/v/unstable)](https://packagist.org/packages/paragonie/constant_time_encoding)
+[![License](https://poser.pugx.org/paragonie/constant_time_encoding/license)](https://packagist.org/packages/paragonie/constant_time_encoding)
+[![Downloads](https://img.shields.io/packagist/dt/paragonie/constant_time_encoding.svg)](https://packagist.org/packages/paragonie/constant_time_encoding)
+
+Based on the [constant-time base64 implementation made by Steve "Sc00bz" Thomas](https://github.com/Sc00bz/ConstTimeEncoding),
+this library aims to offer character encoding functions that do not leak
+information about what you are encoding/decoding via processor cache 
+misses. Further reading on [cache-timing attacks](http://blog.ircmaxell.com/2014/11/its-all-about-time.html).
+
+Our fork offers the following enchancements:
+
+* `mbstring.func_overload` resistance
+* Unit tests
+* Composer- and Packagist-ready
+* Base16 encoding
+* Base32 encoding
+* Uses `pack()` and `unpack()` instead of `chr()` and `ord()`
+
+## PHP Version Requirements
+
+Version 2 of this library should work on **PHP 7** or newer. For PHP 5
+support, see [the v1.x branch](https://github.com/paragonie/constant_time_encoding/tree/v1.x).
+
+If you are adding this as a dependency to a project intended to work on both PHP 5 and PHP 7, please set the required version to `^1|^2` instead of just `^1` or `^2`.
+
+## How to Install
+
+```sh
+composer require paragonie/constant_time_encoding
+```
+
+## How to Use
+
+```php
+use ParagonIE\ConstantTime\Encoding;
+
+// possibly (if applicable): 
+// require 'vendor/autoload.php';
+
+$data = random_bytes(32);
+echo Encoding::base64Encode($data), "\n";
+echo Encoding::base32EncodeUpper($data), "\n";
+echo Encoding::base32Encode($data), "\n";
+echo Encoding::hexEncode($data), "\n";
+echo Encoding::hexEncodeUpper($data), "\n";
+```
+
+Example output:
+ 
+```
+1VilPkeVqirlPifk5scbzcTTbMT2clp+Zkyv9VFFasE=
+2VMKKPSHSWVCVZJ6E7SONRY3ZXCNG3GE6ZZFU7TGJSX7KUKFNLAQ====

+D558A53E4795AA2AE53E27E4E6C71BDCC4D36CC4F6725A7E664CAFF551456AC1
+```
+
+If you only need a particular variant, you can just reference the 
+required class like so:
+
+```php
+use ParagonIE\ConstantTime\Base64;
+use ParagonIE\ConstantTime\Base32;
+
+$data = random_bytes(32);
+echo Base64::encode($data), "\n";
+echo Base32::encode($data), "\n";
+```
+
+Example output:
+
+```

+2vmkkpshswvcvzj6e7sonry3zxcng3ge6zzfu7tgjsx7kukfnlaq====
+```
+
+## Support Contracts
+
+If your company uses this library in their products or services, you may be
+interested in [purchasing a support contract from Paragon Initiative Enterprises](https://paragonie.com/enterprise).
