+bs58
+====
+
+[![build status](https://travis-ci.org/cryptocoinjs/bs58.svg)](https://travis-ci.org/cryptocoinjs/bs58)
+
+JavaScript component to compute base 58 encoding. This encoding is typically used for crypto currencies such as Bitcoin.
+
+**Note:** If you're looking for **base 58 check** encoding, see: [https://github.com/bitcoinjs/bs58check](https://github.com/bitcoinjs/bs58check), which depends upon this library.
+
+
+Install
+-------
+
+    npm i --save bs58
+
+
+API
+---
+
+### encode(input)
+
+`input` must be a `Uint8Array`, `Buffer`, or an `Array`. It returns a `string`.
+
+**example**:
+
+```js
+const bs58 = require('bs58')
+
+const bytes = Uint8Array.from([
+    0, 60,  23, 110, 101, 155, 234,
+   15, 41, 163, 233, 191, 120, 128,
+  193, 18, 177, 179,  27,  77, 200,
+   38, 38, 129, 135
+])
+const address = bs58.encode(bytes)
+console.log(address)
+// => 16UjcYNBG9GTK4uq2f7yYEbuifqCzoLMGS
+```
+
+
+### decode(input)
+
+`input` must be a base 58 encoded string. Returns a Uint8Array.
+
+**example**:
+
+```js
+const bs58 = require('bs58')
+
+const address = '16UjcYNBG9GTK4uq2f7yYEbuifqCzoLMGS'
+const bytes = bs58.decode(address)
+// See uint8array-tools package for helpful hex encoding/decoding/compare tools
+console.log(Buffer.from(bytes).toString('hex'))
+// => 003c176e659bea0f29a3e9bf7880c112b1b31b4dc826268187
+```
+
+Browser
+-----------
+You can use this module in the browser. Install Browserify:
+
+```bash
+npm install -g browserify
+```
+
+then run:
+
+```bash
+browserify node_modules/bs58/index.js -o bs58.bundle.js --standalone bs58
+```
+
+Hack / Test

+# Changelog
+
+All notable changes to this project will be documented in this file. See [standard-version](https://github.com/conventional-changelog/standard-version) for commit guidelines.
+
+## [9.0.0](https://github.com/uuidjs/uuid/compare/v8.3.2...v9.0.0) (2022-09-05)
+
+### ⚠ BREAKING CHANGES
+
+- Drop Node.js 10.x support. This library always aims at supporting one EOLed LTS release which by this time now is 12.x which has reached EOL 30 Apr 2022.
+
+- Remove the minified UMD build from the package.
+
+  Minified code is hard to audit and since this is a widely used library it seems more appropriate nowadays to optimize for auditability than to ship a legacy module format that, at best, serves educational purposes nowadays.
+
+  For production browser use cases, users should be using a bundler. For educational purposes, today's online sandboxes like replit.com offer convenient ways to load npm modules, so the use case for UMD through repos like UNPKG or jsDelivr has largely vanished.
+
+- Drop IE 11 and Safari 10 support. Drop support for browsers that don't correctly implement const/let and default arguments, and no longer transpile the browser build to ES2015.
+
+  This also removes the fallback on msCrypto instead of the crypto API.
+
+  Browser tests are run in the first supported version of each supported browser and in the latest (as of this commit) version available on Browserstack.
+

+## [8.0.0](https://github.com/uuidjs/uuid/compare/v7.0.3...v8.0.0) (2020-04-29)
+
+### ⚠ BREAKING CHANGES
+
+- For native ECMAScript Module (ESM) usage in Node.js only named exports are exposed, there is no more default export.
+
+  ```diff
+  -import uuid from 'uuid';
+  -console.log(uuid.v4()); // -> 'cd6c3b08-0adc-4f4b-a6ef-36087a1c9869'
+  +import { v4 as uuidv4 } from 'uuid';
+  +uuidv4(); // ⇨ '9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d'
+  ```
+
+- Deep requiring specific algorithms of this library like `require('uuid/v4')`, which has been deprecated in `uuid@7`, is no longer supported.
+
+  Instead use the named exports that this module exports.
+
+  For ECMAScript Modules (ESM):
+
+  ```diff
+  -import uuidv4 from 'uuid/v4';
+  +import { v4 as uuidv4 } from 'uuid';
+  uuidv4();
+  ```
+
+  For CommonJS:
+
+  ```diff
+  -const uuidv4 = require('uuid/v4');
+  +const { v4: uuidv4 } = require('uuid');
+  uuidv4();
+  ```
+
+### Features
+
+- native Node.js ES Modules (wrapper approach) ([#423](https://github.com/uuidjs/uuid/issues/423)) ([2d9f590](https://github.com/uuidjs/uuid/commit/2d9f590ad9701d692625c07ed62f0a0f91227991)), closes [#245](https://github.com/uuidjs/uuid/issues/245) [#419](https://github.com/uuidjs/uuid/issues/419) [#342](https://github.com/uuidjs/uuid/issues/342)
+- remove deep requires ([#426](https://github.com/uuidjs/uuid/issues/426)) ([daf72b8](https://github.com/uuidjs/uuid/commit/daf72b84ceb20272a81bb5fbddb05dd95922cbba))
+
+### Bug Fixes
+

+## [7.0.0](https://github.com/uuidjs/uuid/compare/v3.4.0...v7.0.0) (2020-02-24)
+
+### ⚠ BREAKING CHANGES
+
+- The default export, which used to be the v4() method but which was already discouraged in v3.x of this library, has been removed.
+- Explicitly note that deep imports of the different uuid version functions are deprecated and no longer encouraged and that ECMAScript module named imports should be used instead. Emit a deprecation warning for people who deep-require the different algorithm variants.
+- Remove builtin support for insecure random number generators in the browser. Users who want that will have to supply their own random number generator function.
+- Remove support for generating v3 and v5 UUIDs in Node.js<4.x
+- Convert code base to ECMAScript Modules (ESM) and release CommonJS build for node and ESM build for browser bundlers.

+
+## API
+
+### uuid.NIL
+
+The nil UUID string (all zeros).
+
+Example:
+
+```javascript
+import { NIL as NIL_UUID } from 'uuid';
+
+NIL_UUID; // ⇨ '00000000-0000-0000-0000-000000000000'
+```
+
+### uuid.parse(str)
+
+Convert UUID string to array of bytes
+
+|           |                                          |
+| --------- | ---------------------------------------- |
+| `str`     | A valid UUID `String`                    |
+| _returns_ | `Uint8Array[16]`                         |
+| _throws_  | `TypeError` if `str` is not a valid UUID |
+
+Note: Ordering of values in the byte arrays used by `parse()` and `stringify()` follows the left &Rarr; right order of hex-pairs in UUID strings. As shown in the example below.
+
+Example:
+
+```javascript
+import { parse as uuidParse } from 'uuid';
+
+// Parse a UUID
+const bytes = uuidParse('6ec0bd7f-11c0-43da-975e-2a8ad9ebae0b');
+
+// Convert to hex strings to show byte order (for documentation purposes)
+[...bytes].map((v) => v.toString(16).padStart(2, '0')); // ⇨ 
+  // [
+  //   '6e', 'c0', 'bd', '7f',
+  //   '11', 'c0', '43', 'da',
+  //   '97', '5e', '2a', '8a',
+  //   'd9', 'eb', 'ae', '0b'
+  // ]
+```
+
+### uuid.stringify(arr[, offset])
+
+Convert array of bytes to UUID string
+
+|                |                                                                              |
+| -------------- | ---------------------------------------------------------------------------- |
+| `arr`          | `Array`-like collection of 16 values (starting from `offset`) between 0-255. |
+| [`offset` = 0] | `Number` Starting index in the Array                                         |
+| _returns_      | `String`                                                                     |
+| _throws_       | `TypeError` if a valid UUID string cannot be generated                       |
+
+Note: Ordering of values in the byte arrays used by `parse()` and `stringify()` follows the left &Rarr; right order of hex-pairs in UUID strings. As shown in the example below.
+
+Example:
+
+```javascript
+import { stringify as uuidStringify } from 'uuid';
+
+const uuidBytes = [
+  0x6e, 0xc0, 0xbd, 0x7f, 0x11, 0xc0, 0x43, 0xda, 0x97, 0x5e, 0x2a, 0x8a, 0xd9, 0xeb, 0xae, 0x0b,
+];
+
+uuidStringify(uuidBytes); // ⇨ '6ec0bd7f-11c0-43da-975e-2a8ad9ebae0b'
+```
+
+### uuid.v1([options[, buffer[, offset]]])
+
+Create an RFC version 1 (timestamp) UUID
+
+|  |  |
+| --- | --- |
+| [`options`] | `Object` with one or more of the following properties: |
+| [`options.node` ] | RFC "node" field as an `Array[6]` of byte values (per 4.1.6) |
+| [`options.clockseq`] | RFC "clock sequence" as a `Number` between 0 - 0x3fff |
+| [`options.msecs`] | RFC "timestamp" field (`Number` of milliseconds, unix epoch) |
+| [`options.nsecs`] | RFC "timestamp" field (`Number` of nanseconds to add to `msecs`, should be 0-10,000) |
+| [`options.random`] | `Array` of 16 random bytes (0-255) |
+| [`options.rng`] | Alternative to `options.random`, a `Function` that returns an `Array` of 16 random bytes (0-255) |
+| [`buffer`] | `Array \| Buffer` If specified, uuid will be written here in byte-form, starting at `offset` |
+| [`offset` = 0] | `Number` Index to start writing UUID bytes in `buffer` |
+| _returns_ | UUID `String` if no `buffer` is specified, otherwise returns `buffer` |
+| _throws_ | `Error` if more than 10M UUIDs/sec are requested |
+
+Note: The default [node id](https://tools.ietf.org/html/rfc4122#section-4.1.6) (the last 12 digits in the UUID) is generated once, randomly, on process startup, and then remains unchanged for the duration of the process.
+
+Note: `options.random` and `options.rng` are only meaningful on the very first call to `v1()`, where they may be passed to initialize the internal `node` and `clockseq` fields.
+
+Example:
+
+```javascript
+import { v1 as uuidv1 } from 'uuid';
+
+uuidv1(); // ⇨ '2c5ea4c0-4067-11e9-8bad-9b1deb4d3b7d'
+```
+
+Example using `options`:
+
+```javascript
+import { v1 as uuidv1 } from 'uuid';
+
+const v1options = {
+  node: [0x01, 0x23, 0x45, 0x67, 0x89, 0xab],
+  clockseq: 0x1234,
+  msecs: new Date('2011-11-01').getTime(),
+  nsecs: 5678,
+};
+uuidv1(v1options); // ⇨ '710b962e-041c-11e1-9234-0123456789ab'
+```
+
+### uuid.v3(name, namespace[, buffer[, offset]])
+
+Create an RFC version 3 (namespace w/ MD5) UUID
+
+API is identical to `v5()`, but uses "v3" instead.
+
+&#x26a0;&#xfe0f; Note: Per the RFC, "_If backward compatibility is not an issue, SHA-1 [Version 5] is preferred_."
+
+### uuid.v4([options[, buffer[, offset]]])
+
+Create an RFC version 4 (random) UUID
+
+|  |  |
+| --- | --- |
+| [`options`] | `Object` with one or more of the following properties: |
+| [`options.random`] | `Array` of 16 random bytes (0-255) |
+| [`options.rng`] | Alternative to `options.random`, a `Function` that returns an `Array` of 16 random bytes (0-255) |
+| [`buffer`] | `Array \| Buffer` If specified, uuid will be written here in byte-form, starting at `offset` |
+| [`offset` = 0] | `Number` Index to start writing UUID bytes in `buffer` |
+| _returns_ | UUID `String` if no `buffer` is specified, otherwise returns `buffer` |
+
+Example:
+
+```javascript
+import { v4 as uuidv4 } from 'uuid';
+
+uuidv4(); // ⇨ '1b9d6bcd-bbfd-4b2d-9b5d-ab8dfbbd4bed'
+```
+
+Example using predefined `random` values:
+
+```javascript
+import { v4 as uuidv4 } from 'uuid';
+
+const v4options = {
+  random: [
+    0x10, 0x91, 0x56, 0xbe, 0xc4, 0xfb, 0xc1, 0xea, 0x71, 0xb4, 0xef, 0xe1, 0x67, 0x1c, 0x58, 0x36,
+  ],
+};
+uuidv4(v4options); // ⇨ '109156be-c4fb-41ea-b1b4-efe1671c5836'
+```
+
+### uuid.v5(name, namespace[, buffer[, offset]])
+
+Create an RFC version 5 (namespace w/ SHA-1) UUID
+
+|  |  |
+| --- | --- |
+| `name` | `String \| Array` |
+| `namespace` | `String \| Array[16]` Namespace UUID |
+| [`buffer`] | `Array \| Buffer` If specified, uuid will be written here in byte-form, starting at `offset` |
+| [`offset` = 0] | `Number` Index to start writing UUID bytes in `buffer` |
+| _returns_ | UUID `String` if no `buffer` is specified, otherwise returns `buffer` |
+
+Note: The RFC `DNS` and `URL` namespaces are available as `v5.DNS` and `v5.URL`.
+
+Example with custom namespace:
+
+```javascript
+import { v5 as uuidv5 } from 'uuid';
+
+// Define a custom namespace.  Readers, create your own using something like
+// https://www.uuidgenerator.net/
+const MY_NAMESPACE = '1b671a64-40d5-491e-99b0-da01ff1f3341';
+
+uuidv5('Hello, World!', MY_NAMESPACE); // ⇨ '630eb68f-e0fa-5ecc-887a-7c7a62614681'
+```
+
+Example with RFC `URL` namespace:
+
+```javascript
+import { v5 as uuidv5 } from 'uuid';
+
+uuidv5('https://www.w3.org/', uuidv5.URL); // ⇨ 'c106a26a-21bb-5538-8bf2-57095d1976c1'
+```
+
+### uuid.validate(str)
+
+Test a string to see if it is a valid UUID
+
+|           |                                                     |
+| --------- | --------------------------------------------------- |
+| `str`     | `String` to validate                                |
+| _returns_ | `true` if string is a valid UUID, `false` otherwise |
+
+Example:
+
+```javascript
+import { validate as uuidValidate } from 'uuid';
+
+uuidValidate('not a UUID'); // ⇨ false
+uuidValidate('6ec0bd7f-11c0-43da-975e-2a8ad9ebae0b'); // ⇨ true
+```
+
+Using `validate` and `version` together it is possible to do per-version validation, e.g. validate for only v4 UUIds.
+
+```javascript
+import { version as uuidVersion } from 'uuid';
+import { validate as uuidValidate } from 'uuid';
+
+function uuidValidateV4(uuid) {
+  return uuidValidate(uuid) && uuidVersion(uuid) === 4;
+}
+
+const v1Uuid = 'd9428888-122b-11e1-b85c-61cd3cbb3210';
+const v4Uuid = '109156be-c4fb-41ea-b1b4-efe1671c5836';
+
+uuidValidateV4(v4Uuid); // ⇨ true
+uuidValidateV4(v1Uuid); // ⇨ false
+```
+
+### uuid.version(str)
+
+Detect RFC version of a UUID
+
+|           |                                          |
+| --------- | ---------------------------------------- |
+| `str`     | A valid UUID `String`                    |
+| _returns_ | `Number` The RFC version of the UUID     |
+| _throws_  | `TypeError` if `str` is not a valid UUID |
+
+Example:
+
+```javascript
+import { version as uuidVersion } from 'uuid';
+
+uuidVersion('45637ec4-c85f-11ea-87d0-0242ac130003'); // ⇨ 1
+uuidVersion('6ec0bd7f-11c0-43da-975e-2a8ad9ebae0b'); // ⇨ 4
+```
+
+## Command Line
+
+UUIDs can be generated from the command line using `uuid`.
+
+```shell
+$ npx uuid
+ddeb27fb-d9a0-4624-be4d-4615062daed4
+```
+
+The default is to generate version 4 UUIDS, however the other versions are supported. Type `uuid --help` for details:
+
+```shell
+$ npx uuid --help
+
+Usage:
+  uuid
+  uuid v1
+  uuid v3 <name> <namespace uuid>
+  uuid v4
+  uuid v5 <name> <namespace uuid>
+  uuid --help
+
+Note: <namespace uuid> may be "URL" or "DNS" to use the corresponding UUIDs
+defined by RFC4122
+```
+
+## ECMAScript Modules
+
+This library comes with [ECMAScript Modules](https://www.ecma-international.org/ecma-262/6.0/#sec-modules) (ESM) support for Node.js versions that support it ([example](./examples/node-esmodules/)) as well as bundlers like [rollup.js](https://rollupjs.org/guide/en/#tree-shaking) ([example](./examples/browser-rollup/)) and [webpack](https://webpack.js.org/guides/tree-shaking/) ([example](./examples/browser-webpack/)) (targeting both, Node.js and browser environments).
+
+```javascript
+import { v4 as uuidv4 } from 'uuid';
+uuidv4(); // ⇨ '1b9d6bcd-bbfd-4b2d-9b5d-ab8dfbbd4bed'
+```
+
+To run the examples you must first create a dist build of this library in the module root:
+
+```shell
+npm run build
+```
+
+## CDN Builds
+
+### ECMAScript Modules
+
+To load this module directly into modern browsers that [support loading ECMAScript Modules](https://caniuse.com/#feat=es6-module) you can make use of [jspm](https://jspm.org/):
+
+```html
+<script type="module">
+  import { v4 as uuidv4 } from 'https://jspm.dev/uuid';
+  console.log(uuidv4()); // ⇨ '1b9d6bcd-bbfd-4b2d-9b5d-ab8dfbbd4bed'
+</script>
+```
+
+### UMD
+
+As of `uuid@9` [UMD (Universal Module Definition)](https://github.com/umdjs/umd) builds are no longer shipped with this library.
+
+If you need a UMD build of this library, use a bundler like Webpack or Rollup. Alternatively, refer to the documentation of [`uuid@8.3.2`](https://github.com/uuidjs/uuid/blob/v8.3.2/README.md#umd) which was the last version that shipped UMD builds.
+
+## Known issues
+
+### Duplicate UUIDs (Googlebot)
+
+This module may generate duplicate UUIDs when run in clients with _deterministic_ random number generators, such as [Googlebot crawlers](https://developers.google.com/search/docs/advanced/crawling/overview-google-crawlers). This can cause problems for apps that expect client-generated UUIDs to always be unique. Developers should be prepared for this and have a strategy for dealing with possible collisions, such as:
+
+- Check for duplicate UUIDs, fail gracefully
+- Disable write operations for Googlebot clients
+
+### "getRandomValues() not supported"
+
+This error occurs in environments where the standard [`crypto.getRandomValues()`](https://developer.mozilla.org/en-US/docs/Web/API/Crypto/getRandomValues) API is not supported. This issue can be resolved by adding an appropriate polyfill:
+
+### React Native / Expo
+
+1. Install [`react-native-get-random-values`](https://github.com/LinusU/react-native-get-random-values#readme)
+1. Import it _before_ `uuid`. Since `uuid` might also appear as a transitive dependency of some other imports it's safest to just import `react-native-get-random-values` as the very first thing in your entry point:
+
+```javascript
+import 'react-native-get-random-values';
+import { v4 as uuidv4 } from 'uuid';
+```
+
+Note: If you are using Expo, you must be using at least `react-native-get-random-values@1.5.0` and `expo@39.0.0`.
+
+### Web Workers / Service Workers (Edge <= 18)
+
+[In Edge <= 18, Web Crypto is not supported in Web Workers or Service Workers](https://caniuse.com/#feat=cryptography) and we are not aware of a polyfill (let us know if you find one, please).
+
+### IE 11 (Internet Explorer)
+
+Support for IE11 and other legacy browsers has been dropped as of `uuid@9`. If you need to support legacy browsers, you can always transpile the uuid module source yourself (e.g. using [Babel](https://babeljs.io/)).
+
+## Upgrading From `uuid@7`
+
+### Only Named Exports Supported When Using with Node.js ESM
+
+`uuid@7` did not come with native ECMAScript Module (ESM) support for Node.js. Importing it in Node.js ESM consequently imported the CommonJS source with a default export. This library now comes with true Node.js ESM support and only provides named exports.
+
+Instead of doing:
+
+```javascript
+import uuid from 'uuid';
+uuid.v4();
+```
+
+you will now have to use the named exports:
+
+```javascript
+import { v4 as uuidv4 } from 'uuid';
+uuidv4();
+```
+
+### Deep Requires No Longer Supported
+
+Deep requires like `require('uuid/v4')` [which have been deprecated in `uuid@7`](#deep-requires-now-deprecated) are no longer supported.
+
+## Upgrading From `uuid@3`
+
+"_Wait... what happened to `uuid@4` thru `uuid@6`?!?_"
+
+In order to avoid confusion with RFC [version 4](#uuidv4options-buffer-offset) and [version 5](#uuidv5name-namespace-buffer-offset) UUIDs, and a possible [version 6](http://gh.peabody.io/uuidv6/), releases 4 thru 6 of this module have been skipped.
+
+### Deep Requires Now Deprecated
+
+`uuid@3` encouraged the use of deep requires to minimize the bundle size of browser builds:
+
+```javascript
+const uuidv4 = require('uuid/v4'); // <== NOW DEPRECATED!
+uuidv4();
+```
+
+As of `uuid@7` this library now provides ECMAScript modules builds, which allow packagers like Webpack and Rollup to do "tree-shaking" to remove dead code. Instead, use the `import` syntax:
+
+```javascript
+import { v4 as uuidv4 } from 'uuid';
+uuidv4();
+```
+
+... or for CommonJS:
+
+```javascript
+const { v4: uuidv4 } = require('uuid');
+uuidv4();
+```
+
+### Default Export Removed
+
+`uuid@3` was exporting the Version 4 UUID method as a default export:
+
+```javascript
+const uuid = require('uuid'); // <== REMOVED!
+```
+
+This usage pattern was already discouraged in `uuid@3` and has been removed in `uuid@7`.
