The standard comprises three block ciphers, AES-128, AES-192 and AES-256, adopted from a larger collection originally published as Rijndael. Each of these ciphers has a 128-bit block size, with key sizes of 128, 192 and 256 bits, respectively. The AES ciphers have been analyzed extensively and are now used worldwide, as was the case with its predecessor, the Data Encryption Standard (DES). </textarea> <tr><td id="cipherinfo">  <tr><td> <select id="cipheralg"> <option>AES-128</option> </select> <input size="40" id="password" value="qwerty"></input> <input type="button" value="Encrypt" onclick="ed.encrypt()"></input> <input type="button" value="Decrypt" onclick="ed.decrypt()"></input> <tr><td> <textarea cols="60" rows="10" id="cipher"></textarea> </table> <div class="footnote">AES implementation for Habrahabr</div> </body> </html>
