如果你想批量给文章加密的话网上有这方面的插件，就是批量加密已发布文章（ (#‵   ′ )凸这不废话嘛！）

如果想让博客发布日志时都自动加密的话得手动修改代码了，wp-admin/includes/meta-boxes.php 113行，

原始代码：

if ( 'private' == $post->post_status ) {
$post->post_password = '';
$visibility = 'private';
$visibility_trans = __('Private');
} elseif ( !empty( $post->post_password ) ) {
$visibility = 'password';
$visibility_trans = __('Password protected');
} elseif ( $post_type == 'post' && is_sticky( $post->ID ) ) {
$visibility = 'public';
$visibility_trans = __('Public, Sticky');
} else {
$visibility = 'public';
$visibility_trans = __('Public');
}

修改后代码：

if ( 'private' == $post->post_status ) {
$post->post_password = '';
$visibility = 'private';
$visibility_trans = __('Private');
} elseif ( !empty( $post->post_password ) ) {
$visibility = 'password';
$visibility_trans = __('Password protected');
} elseif ( $post_type == 'post' && is_sticky( $post->ID ) ) {
$visibility = 'public';
$visibility_trans = __('Public, Sticky');
} else {
$post->post_password = '123456';
$visibility = 'password';
$visibility_trans = __('Password protected');
}

这样，在发布文章的时候，默认选中的就是密码保护类型，并且已经填写了默认的密码“123456”，如果你需要自定义密码，那——

只好一篇一篇修改密码了！！！！
