+
+<!-- /TOC -->
+
+## Getting Started
+
+This is the full setup guide for installing, configuring and customising
+your dependencies for the library.
+
+> Check out the [Quick Start Guide][docs-quick-start] instead for easier
+> setup especially if you do not need to use any custom base32 / crypto libraries.
+
+### Install the Package
+
+```bash
+npm install @otplib/core
+```
+
+### Choose Your Plugins
+
+#### Adding Crypto
+
+The crypto modules are used to generate the digest used to derive the OTP tokens from.
+By default, Node.js has inbuilt `crypto` functionality, but you might want to replace it
+for certain environments that do not support it.
+
+Currently there are a few crypto plugins available from this project.
+Install one of them. eg: `npm install @otplib/plugin-crypto`
+
+Refer to the [crypto plugins list][docs-plugins-crypto],
+or search for [otplib-plugin crypto][link-npm-search-crypto] on `npm`.
+
+#### Adding Base32
+
+If you're using `Google Authenticator`, you'll need a base32 module for
+encoding and decoding your secrets.
+
+Currently, there are a few base32 plugins available from this project.
+Install one of them. eg: `npm install @otplib/plugin-thirty-two`
+
+Refer to the [base32 plugin list][docs-plugins-base32],
+or search for [otplib-plugin base32][link-npm-search-base32] on `npm`.
+
+### Initialise your Instance
+
+#### Using Classes
+
+```js
+import { HOTP, TOTP, Authenticator } from '@otplib/core';
+
+import { keyDecoder, keyEncoder } from '@otplib/plugin-thirty-two'; // use your chosen base32 plugin
+import { createDigest, createRandomBytes } from '@otplib/plugin-crypto'; // use your chosen crypto plugin
+
+// Setup an OTP instance which you need
+const hotp = new HOTP({ createDigest });
+const totp = new TOTP({ createDigest });
+const authenticator = new Authenticator({
+  createDigest,
+  createRandomBytes,
+  keyDecoder,
+  keyEncoder
+});
+
+// Go forth and generate tokens
+const token = hotp.generate(YOUR_SECRET, 0);
+const token = totp.generate(YOUR_SECRET);
+const token = authenticator.generate(YOUR_SECRET);
+```
+
+#### Using Functions
+
+Alternatively, if you are using the functions directly instead of the classes,
+pass these as options into the functions.
+
+```js
+import {
+  hotpOptions,
+  hotpToken,
+  totpOptions,
+  totpToken,
+  authenticatorOptions,
+  authenticatorToken
+} from 'otplib/core';
+
+// As with classes, import your desired Base32 Plugin and Crypto Plugin.
+// import ...
+
+// Go forth and generate tokens
+const token = hotpToken(YOUR_SECRET, 0, hotpOptions({ createDigest }));
+const token = totpToken(YOUR_SECRET, totpOptions({ createDigest }));
+const token = authenticatorToken(
+  YOUR_SECRET,
+  authenticatorOptions({
+    createDigest,
+    createRandomBytes,
+    keyDecoder,
+    keyEncoder
+  })
+);
+```
+

+
+## About
+
+`otplib` is a JavaScript One Time Password (OTP) library for OTP generation and verification.
+
+It implements both [HOTP][rfc-4226-wiki] - [RFC 4226][rfc-4226]
+and [TOTP][rfc-6238-wiki] - [RFC 6238][rfc-6238],
+and are tested against the test vectors provided in their respective RFC specifications.
+These datasets can be found in the `tests/data` folder.
+
+- [RFC 4226 Dataset][rfc-4226-dataset]
+- [RFC 6238 Dataset][rfc-6238-dataset]
+
+This library is also compatible with [Google Authenticator](https://github.com/google/google-authenticator),
+and includes additional methods to allow you to work with Google Authenticator.
+
+## Features
+
+- Typescript support
+- [Class][link-mdn-classes] interfaces
+- [Function][link-mdn-functions] interfaces
+- [Async][link-mdn-async] interfaces
+- Pluggable modules (crypto / base32)
+  - `crypto (node)`
+  - `crypto-js`
+  - `@ronomon/crypto-async`
+  - `thirty-two`
+  - `base32-encode` + `base32-decode`
+- Presets provided
+  - `browser`
+  - `default (node)`
+  - `default-async (same as default, but with async methods)`
+  - `v11 (adapter for previous version)`
+
+## Quick Start
+
+> If you need to customise your base32 or crypto libraries,
+> check out the [In-Depth Guide][docs-in-depth] and [Available Packages][docs-available-packages]
+
+### In Node.js
+
+```bash
+npm install otplib --save
+```
+
+```js
+import { authenticator } from 'otplib';
+
+const secret = 'KVKFKRCPNZQUYMLXOVYDSQKJKZDTSRLD';
+// Alternative:
+// const secret = authenticator.generateSecret();
+// Note: .generateSecret() is only available for authenticator and not totp/hotp
+
+const token = authenticator.generate(secret);
+
+try {
+  const isValid = authenticator.check(token, secret);
+  // or
+  const isValid = authenticator.verify({ token, secret });
+} catch (err) {
+  // Possible errors
+  // - options validation
+  // - "Invalid input - it is not base32 encoded string" (if thiry-two is used)
+  console.error(err);
+}
+```
+
+Please replace "authenticator" with "totp" or "hotp" depending on your requirements.
+
+```js
+// For TOTP
+import { totp } from 'otplib';
+const token = totp.generate(secret);
+const isValid = totp.check(token, secret);
+const isValid = totp.verify({ token, secret });
+
+// For HOTP
+import { hotp } from 'otplib';
+const token = hotp.generate(secret, counter);
+const isValid = hotp.check(token, secret, counter);
+const isValid = hotp.verify({ token, secret, counter });
+```
+
+For all available APIs, please refer to [API Documentation][project-v-api].
+
+### In Browser
+
+The browser preset is a self-contained `umd` module, and it is provided in a separate bundle.
+
+```bash
+npm install @otplib/preset-browser --save
+```
+
+The following is an example, where we are using the scripts hosted by `unpkg.com`.
+
+```html
+<script src="https://unpkg.com/@otplib/preset-browser@^12.0.0/buffer.js"></script>
+<script src="https://unpkg.com/@otplib/preset-browser@^12.0.0/index.js"></script>
+
+<script type="text/javascript">
+  // window.otplib.authenticator
+  // window.otplib.hotp
+  // window.otplib.totp
+</script>
+```
+
+For more details, please refer to the [@otplib/preset-browser documentation][docs-preset-browser].

+### Versioning
+
+This library follows `semver`. As such, major version bumps usually mean API changes or behavior changes.
+Please check [upgrade notes](https://github.com/yeojz/otplib/wiki/upgrade-notes) for more information,
+especially before making any major upgrades.
+
+To simplify releases, all packages within this repository have their versions synced.
+Therefore, if there are any releases or updates to a package, we will bump all packages.
+
+Check out the release notes associated with each tagged versions
+in the [releases](https://github.com/yeojz/otplib/releases) page.
+
+| Release Type      | Version Pattern | Command                   |                                       |

+
+### Migrating from v11.x
+
+> v12.x is a huge architectural and language rewrite. Please check out the docs if you are migrating.
+> A preset adapter is available to provide methods that behave like `v11.x` of `otplib`.
+
+```js
+// Update
+import { authenticator } from 'otplib'; // v11.x
+// to
+import { authenticator } from '@otplib/preset-v11';
+
+// There should be no changes to your current code.
+// However, deprecated or modified class methods will have console.warn.
+```
+
+### Available Options
+
+All instantiated classes will have their options inherited from their respective options
+generator. i.e. HOTP from `hotpOptions`, TOTP from `totpOptions`
+and Authenticator from `authenticatorOptions`.
+
+All OTP classes have an object setter and getter method to override these default options.
+
+For example,
+
+```js
+import { authenticator, totp, hotp } from 'otplib';
+
+// setting
+authenticator.options = { digits: 6 };
+totp.options = { digits: 6 };
+hotp.options = { digits: 6 };
+
+// getting
+const opts = authenticator.options;
+const opts = totp.options;
+const opts = hotp.options;
+
+// reset to default
+authenticator.resetOptions();
+totp.resetOptions();
+hotp.resetOptions();
+
+// getting all options, with validation
+// and backfilled with library defaults
+const opts = authenticator.allOptions();
+const opts = totp.allOptions();
+const opts = hotp.allOptions();
+```
+

+
+## Appendix
+
+### Type Definitions
+
+`TypeScript` support was introduced in `v10.0.0`, which added type definitions over `.js` files.
+
+As of `v12.0.0`, the library has been re-written in Typescript from the ground up.
+
+### Async Support
+
+`async` support was introduced in `v12.0.0` as an additional core library.
+
+This was added as some libraries like [expo.io][link-expo-crypto] or even
+the browser API ([window.Crypto.subtle][link-mdn-subtlecrypto]) started providing
+only async methods.
+
+You to find more details in the [core-async][docs-core-async] folder.
+
+### Browser Compatiblity
+
+`@otplib/preset-browser` is a `umd` bundle with some node modules replaced to reduce the browser size.
+
+The approximate size for the **optimised, minified + gzipped** bundle is **9.53KB**.
+Paired with the gzipped browser `buffer.js` module, it would be about `7.65KB + 9.53KB = 17.18KB`.
+
+For more details, please refer to the [@otplib/preset-browser documentation][docs-preset-browser].
+
+### Length of Secrets
+
+In [RFC 6238][rfc-6238], the secret / seed length for different algorithms are predefined:
+
+```txt
+HMAC-SHA1 - 20 bytes
+HMAC-SHA256 - 32 bytes
+HMAC-SHA512 - 64 bytes
+```
+
+As such, the length of the secret provided (after any decoding) will be padded and sliced
+according to the expected length for respective algorithms.
+
+### Google Authenticator
+
+#### Difference between Authenticator and TOTP
+
+The default encoding option has been set to `hex` (Authenticator) instead of `ascii` (TOTP).
+
+#### RFC3548 Base32
+
+> Note: [RFC4648][rfc-4648] obseletes [RFC 3548][rfc-3548].
+> Any encoders following the newer specifications will work.
+
+Google Authenticator requires keys to be base32 encoded.
+It also requires the base32 encoder to be [RFC 3548][rfc-3548] compliant.
+
+OTP calculation will still work should you want to use
+other base32 encoding methods (like Crockford's Base32)
+but it will NOT be compatible with Google Authenticator.
+
+```js
+const secret = authenticator.generateSecret(); // base32 encoded hex secret key
+const token = authenticator.generate(secret);
+```
+
+#### Displaying a QR code
+
+You may want to generate and display a QR Code so that users can scan
+instead of manually entering the secret. Google Authenticator and similar apps
+take in a QR code that holds a URL with the protocol `otpauth://`,
+which you get from `authenticator.keyuri`.
+
+Google Authenticator will ignore the `algorithm`, `digits`, and `step` options.
+See the [keyuri documentation](https://github.com/google/google-authenticator/wiki/Key-Uri-Format)
+for more information.
+
+If you are using a different authenticator app, check the documentation
+for that app to see if any options are ignored, which will result in invalid tokens.
+
+While this library provides the "otpauth" uri, you'll need a library to
+generate the QR Code image.
+
+An example is shown below:
+
+```js
+// npm install qrcode
+import qrcode from 'qrcode';
+import { authenticator } from '@otplib/preset-default';
+
+const user = 'A user name, possibly an email';
+const service = 'A service name';
+
+// v11.x and above
+const otpauth = authenticator.keyuri(user, service, secret);
+
+// v10.x and below
+const otpauth = authenticator.keyuri(
+  encodeURIComponent(user),
+  encodeURIComponent(service),
+  secret
+);
+
+qrcode.toDataURL(otpauth, (err, imageUrl) => {
+  if (err) {
+    console.log('Error with QR');
+    return;
+  }
+  console.log(imageUrl);
+});
+```
+
+> **Note**: For versions `v10.x` and below, `keyuri` does not URI encode
+> `user` and `service`. You'll need to do so before passing in the parameteres.
+
+### Getting Time Remaining / Time Used
+
+Helper methods for getting the remaining time and used time within a validity period
+of a `totp` or `authenticator` token were introduced in `v10.0.0`.
+
+```js
+authenticator.timeUsed(); // or totp.timeUsed();
+authenticator.timeRemaining(); // or totp.timeRemaining();
+
+// The start of a new token would be when:
+// - timeUsed() === 0
+// - timeRemaining() === step
+```
+
+### Using with Expo
+
+[Expo][link-expo-io] contains modified crypto implmentations targeted at the platform.
+While `otplib` does not provide an `expo` specified package, with the re-architecture
+of `otplib`, you can now provide an expo native `createDigest` to the library.
+
+Alternatively, you can make use of crypto provided by `@otplib/plugin-crypto-js` or
+the bundled browser umd module `@otplib/preset-browser`.
+
+Pull Requests are much welcomed for a native expo implementation as well.
+
+### Exploring with local-repl
+
+If you'll like to explore the library with `local-repl` you can do so as well.
+
+```bash
+# after cloning the repo:
+npm run setup
+npm run build
+npx local-repl
+# You should see something like:
+# Node v8.9.4, local-repl 4.0.0
+# otplib 10.0.0
+# Context: otplib
+# [otplib] >
+
+[otplib] > secret = 'KVKFKRCPNZQUYMLXOVYDSQKJKZDTSRLD'
+[otplib] > otplib.authenticator.generate(secret)
+```
+
+### OTP Backup Codes
+
+It is common for services to also provide a set of backup codes to authenticate
+and bypass the OTP step in the event that you are not able to access your 2FA
+device or have misplaced the device.
+
+As this process is separate from the specifications for OTP, this library does not
+provide any backup code related verification logic, and thus would have to be
+implemented separately.

+
+# Tests
+
+Tested using [PNG Suite](http://www.schaik.com/pngsuite/). We read every file into pngjs, output it in standard 8bit colour, synchronously and asynchronously, then compare the original with the newly saved images.
+
+To run the tests, fetch the repo (tests are not distributed via npm) and install with `npm i`, run `npm test`.
+
+The only thing not converted is gamma correction - this is because multiple vendors will do gamma correction differently, so the tests will have different results on different browsers.
+
+In addition we use a tolerance of 3 for 16 bit images in PhantomJS because PhantomJS seems to have non-compliant rules for downscaling 16 bit images.
+
+# Installation
+
+```
+$ npm install pngjs  --save
+```
+
+# Browser
+
+The package has been build with a [Browserify](browserify.org) version (`npm run browserify`) and you can use the browser version by including in your code:
+
+```
+import { PNG } from 'pngjs/browser';
+```
+
+# Example
+
+```js
+var fs = require("fs"),
+  PNG = require("pngjs").PNG;
+
+fs.createReadStream("in.png")
+  .pipe(
+    new PNG({
+      filterType: 4,
+    })
+  )
+  .on("parsed", function () {
+    for (var y = 0; y < this.height; y++) {
+      for (var x = 0; x < this.width; x++) {
+        var idx = (this.width * y + x) << 2;
+
+        // invert color
+        this.data[idx] = 255 - this.data[idx];
+        this.data[idx + 1] = 255 - this.data[idx + 1];
+        this.data[idx + 2] = 255 - this.data[idx + 2];
+
+        // and reduce opacity
+        this.data[idx + 3] = this.data[idx + 3] >> 1;
+      }
+    }
+
+    this.pack().pipe(fs.createWriteStream("out.png"));
+  });
+```
+
+For more examples see `examples` folder.
+
+# Async API
+
+As input any color type is accepted (grayscale, rgb, palette, grayscale with alpha, rgb with alpha) but 8 bit per sample (channel) is the only supported bit depth. Interlaced mode is not supported.
+
+## Class: PNG
+
+`PNG` is readable and writable `Stream`.
+
+### Options
+
+- `width` - use this with `height` if you want to create png from scratch
+- `height` - as above
+- `checkCRC` - whether parser should be strict about checksums in source stream (default: `true`)
+- `deflateChunkSize` - chunk size used for deflating data chunks, this should be power of 2 and must not be less than 256 and more than 32\*1024 (default: 32 kB)
+- `deflateLevel` - compression level for deflate (default: 9)
+- `deflateStrategy` - compression strategy for deflate (default: 3)
+- `deflateFactory` - deflate stream factory (default: `zlib.createDeflate`)
+- `filterType` - png filtering method for scanlines (default: -1 => auto, accepts array of numbers 0-4)
+- `colorType` - the output colorType - see constants. 0 = grayscale, no alpha, 2 = color, no alpha, 4 = grayscale & alpha, 6 = color & alpha. Default currently 6, but in the future may calculate best mode.
+- `inputColorType` - the input colorType - see constants. Default is 6 (RGBA)
+- `bitDepth` - the bitDepth of the output, 8 or 16 bits. Input data is expected to have this bit depth.
+  16 bit data is expected in the system endianness (Default: 8)
+- `inputHasAlpha` - whether the input bitmap has 4 bytes per pixel (rgb and alpha) or 3 (rgb - no alpha).
+- `bgColor` - an object containing red, green, and blue values between 0 and 255
+  that is used when packing a PNG if alpha is not to be included (default: 255,255,255)
+
+### Event "metadata"
+
+`function(metadata) { }`
+Image's header has been parsed, metadata contains this information:
+
+- `width` image size in pixels
+- `height` image size in pixels
+- `palette` image is paletted
+- `color` image is not grayscale
+- `alpha` image contains alpha channel
+- `interlace` image is interlaced
+
+### Event: "parsed"
+
+`function(data) { }`
+Input image has been completely parsed, `data` is complete and ready for modification.
+
+### Event: "error"
+
+`function(error) { }`
+
+### png.parse(data, [callback])
+
+Parses PNG file data. Can be `String` or `Buffer`. Alternatively you can stream data to instance of PNG.
+
+Optional `callback` is once called on `error` or `parsed`. The callback gets
+two arguments `(err, data)`.
+
+Returns `this` for method chaining.
+
+#### Example
+
+```js
+new PNG({ filterType: 4 }).parse(imageData, function (error, data) {
+  console.log(error, data);
+});
+```
+
+### png.pack()
+
+Starts converting data to PNG file Stream.
+
+Returns `this` for method chaining.
+
+### png.bitblt(dst, sx, sy, w, h, dx, dy)
+
+Helper for image manipulation, copies a rectangle of pixels from current (i.e. the source) image (`sx`, `sy`, `w`, `h`) to `dst` image (at `dx`, `dy`).
+
+Returns `this` for method chaining.
+
+For example, the following code copies the top-left 100x50 px of `in.png` into dst and writes it to `out.png`:
+
+```js
+var dst = new PNG({ width: 100, height: 50 });
+fs.createReadStream("in.png")
+  .pipe(new PNG())
+  .on("parsed", function () {
+    this.bitblt(dst, 0, 0, 100, 50, 0, 0);
+    dst.pack().pipe(fs.createWriteStream("out.png"));
+  });
+```
+
+### Property: adjustGamma()
+
+Helper that takes data and adjusts it to be gamma corrected. Note that it is not 100% reliable with transparent colours because that requires knowing the background colour the bitmap is rendered on to.
+
+In tests against PNG suite it compared 100% with chrome on all 8 bit and below images. On IE there were some differences.
+
+The following example reads a file, adjusts the gamma (which sets the gamma to 0) and writes it out again, effectively removing any gamma correction from the image.
+
+```js
+fs.createReadStream("in.png")
+  .pipe(new PNG())
+  .on("parsed", function () {
+    this.adjustGamma();
+    this.pack().pipe(fs.createWriteStream("out.png"));
+  });
+```
+
+### Property: width
+
+Width of image in pixels
+
+### Property: height
+
+Height of image in pixels
+
+### Property: data
+
+Buffer of image pixel data. Every pixel consists 4 bytes: R, G, B, A (opacity).
+
+### Property: gamma
+
+Gamma of image (0 if not specified)
+
+## Packing a PNG and removing alpha (RGBA to RGB)
+
+When removing the alpha channel from an image, there needs to be a background color to correctly
+convert each pixel's transparency to the appropriate RGB value. By default, pngjs will flatten
+the image against a white background. You can override this in the options:
+
+```js
+var fs = require("fs"),
+  PNG = require("pngjs").PNG;
+
+fs.createReadStream("in.png")
+  .pipe(
+    new PNG({
+      colorType: 2,
+      bgColor: {
+        red: 0,
+        green: 255,
+        blue: 0,
+      },
+    })
+  )
+  .on("parsed", function () {
+    this.pack().pipe(fs.createWriteStream("out.png"));
+  });
+```
+
+# Sync API
+
+## PNG.sync
+
+### PNG.sync.read(buffer)
+
+Take a buffer and returns a PNG image. The properties on the image include the meta data and `data` as per the async API above.
+
+```
+var data = fs.readFileSync('in.png');
+var png = PNG.sync.read(data);
+```
+
+### PNG.sync.write(png)
+
+Take a PNG image and returns a buffer. The properties on the image include the meta data and `data` as per the async API above.
+
+```
+var data = fs.readFileSync('in.png');
+var png = PNG.sync.read(data);
+var options = { colorType: 6 };
+var buffer = PNG.sync.write(png, options);
+fs.writeFileSync('out.png', buffer);
+```
+
+### PNG.adjustGamma(src)
+
+Adjusts the gamma of a sync image. See the async adjustGamma.
+
+```
+var data = fs.readFileSync('in.png');
+var png = PNG.sync.read(data);
+PNG.adjustGamma(png);
+```
