[21] Fix | Delete

* $des->setKey('abcdefgh');

[22] Fix | Delete

*

[23] Fix | Delete

* $size = 10 * 1024;

[24] Fix | Delete

* $plaintext = '';

[25] Fix | Delete

* for ($i = 0; $i < $size; $i++) {

[26] Fix | Delete

* $plaintext.= 'a';

[27] Fix | Delete

* }

[28] Fix | Delete

*

[29] Fix | Delete
