+title: Кодирование и декодирование в формате Base64
+slug: Web/API/WindowBase64/Base64_encoding_and_decoding
+translation_of: Glossary/Base64
+---
+<p><strong>Base64</strong> - это группа cхожих <a href="https://en.wikipedia.org/wiki/Binary-to-text_encoding">binary-to-text encoding</a> схем, которые представляют двоичные данные в ASCII-формате методом перевода в radix-64 представление. Термин <em>Base64</em> происходит от a specific <a href="https://en.wikipedia.org/wiki/MIME#Content-Transfer-Encoding">MIME content transfer encoding</a>.</p>
+
+<p>Кодирование Base64 широко используется в случаях, когда требуется перекодировать двоичные данные для передачи по каналу приспособленному для передачи текстовых данных. Это делается с целью защиты двоичных данных от любых возможных повреждений при передаче. Base64 широко используется во многих приложениях, включая электронную почту (<a href="https://en.wikipedia.org/wiki/MIME">MIME</a>), и при сохранении больших объёмов данных в <a href="/en-US/docs/XML">XML</a>.</p>
+
+<p>В языке JavaScript существуют две функции, для кодирования и декодирования данных в/из формат Base64 соответственно:</p>
+
+<ul>
+ <li>{{domxref("WindowBase64.btoa","btoa()")}}</li>
+ <li>{{domxref("WindowBase64.atob","atob()")}}</li>
+</ul>
+
+<p><code><font face="Arial, x-locale-body, sans-serif"><span style="background-color: #ffffff;">Функция </span></font>atob()</code> декодирует Base64-кодированную строку. В противоположность ей, функция <code>btoa()</code> создаёт Base64 кодированную ASCII строку из "строки" бинарных данных.</p>
+
+<p>Обе функции <code>atob()</code> и <code>btoa()</code> работают со строками. Если вам необходимо работать с <a href="/en-US/docs/Web/API/ArrayBuffer"><code>ArrayBuffers</code></a>, обратитесь к <a href="#">этому параграфу</a>.</p>

+<h2 id="The_Unicode_Problem">The "Unicode Problem"</h2>
+
+<p>Since <a href="/en-US/docs/Web/API/DOMString" title="/en-US/docs/Web/API/DOMString"><code>DOMString</code></a>s are 16-bit-encoded strings, in most browsers calling <code>window.btoa</code> on a Unicode string will cause a <code>Character Out Of Range</code> exception if a character exceeds the range of a 8-bit byte (0x00~0xFF). There are two possible methods to solve this problem:</p>
+
+<ul>
+ <li>the first one is to escape the whole string (with UTF-8, see {{jsxref("encodeURIComponent")}}) and then encode it;</li>
+ <li>the second one is to convert the UTF-16 <a href="/en-US/docs/Web/API/DOMString" title="/en-US/docs/Web/API/DOMString"><code>DOMString</code></a> to an UTF-8 array of characters and then encode it.</li>
+</ul>
+
+<p>Here are the two possible methods.</p>
+
+<h3 id="Solution_1_–_escaping_the_string_before_encoding_it">Solution #1 – escaping the string before encoding it</h3>
+
+<pre class="brush:js">function b64EncodeUnicode(str) {
+    // first we use encodeURIComponent to get percent-encoded UTF-8,
+    // then we convert the percent encodings into raw bytes which
+    // can be fed into btoa.
+    return btoa(encodeURIComponent(str).replace(/%([0-9A-F]{2})/g,
+        function toSolidBytes(match, p1) {
+            return String.fromCharCode('0x' + p1);
+    }));
+}
+
+b64EncodeUnicode('✓ à la mode'); // "4pyTIMOgIGxhIG1vZGU="
+b64EncodeUnicode('\n'); // "Cg=="
+</pre>
+
+<p>To decode the Base64-encoded value back into a String:</p>
+
+<pre class="brush: js">function b64DecodeUnicode(str) {
+    // Going backwards: from bytestream, to percent-encoding, to original string.
+    return decodeURIComponent(atob(str).split('').map(function(c) {
+        return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2);
+    }).join(''));
+}
+
+b64DecodeUnicode('4pyTIMOgIGxhIG1vZGU='); // "✓ à la mode"
+b64DecodeUnicode('Cg=='); // "\n"
+</pre>
+
+<p><a href="https://github.com/coolaj86/unibabel-js">Unibabel</a> implements common conversions using this strategy.</p>
+
+<h3 id="Solution_2_–_rewrite_the_DOMs_atob_and_btoa_using_JavaScripts_TypedArrays_and_UTF-8">Solution #2 – rewrite the DOMs <code>atob()</code> and <code>btoa()</code> using JavaScript's <code>TypedArray</code>s and UTF-8</h3>
+
+<p>Use a <a href="/en-US/docs/Web/API/TextEncoder">TextEncoder</a> polyfill such as <a href="https://github.com/inexorabletash/text-encoding">TextEncoding</a> (also includes legacy windows, mac, and ISO encodings), <a href="https://github.com/coolaj86/TextEncoderLite">TextEncoderLite</a>, combined with a <a href="https://github.com/feross/buffer">Buffer</a> and a Base64 implementation such as <a href="https://github.com/beatgammit/base64-js">base64-js</a>.</p>
+
+<p>When a native <code>TextEncoder</code> implementation is not available, the most light-weight solution would be to use <a href="https://github.com/coolaj86/TextEncoderLite">TextEncoderLite</a> with <a href="https://github.com/beatgammit/base64-js">base64-js</a>. Use the browser implementation when you can.</p>
+
+<p>The following function implements such a strategy. It assumes base64-js imported as <code>&lt;script type="text/javascript" src="base64js.min.js"/&gt;</code>. Note that TextEncoderLite only works with UTF-8.</p>
+
+<pre class="brush: js">function Base64Encode(str, encoding = 'utf-8') {
+    var bytes = new (TextEncoder || TextEncoderLite)(encoding).encode(str);
+    return base64js.fromByteArray(bytes);
+}
+
+function Base64Decode(str, encoding = 'utf-8') {
+    var bytes = base64js.toByteArray(str);
+    return new (TextDecoder || TextDecoderLite)(encoding).decode(bytes);
+}
+</pre>

+
+<p>Вы можете воспользоваться этим способом, чтобы избежать проблем при передаче данных через сетевое соединение. Для этого нужно перекодировать данные в base64 и отправить их, и на другой стороне с помощью метода <code>{{domxref("WindowBase64.atob","window.atob()")}}</code> декодировать полученные данные в исходный вид. Например, вы можете перекодировать управляющие символы ASCII с 0 до 31.</p>
+
+<p><code>btoa()</code> также доступна для XPCOM компонентов реализованных в JavaScript, даже если <a href="/en-US/docs/DOM/window" title="DOM/window"><code>window</code></a> не является глобальным объектом в компонентах.</p>
