Now I can read that epub without DRM trouble. That means DRM is useless. Isn't it? How can I secure it more? |

Now if I have the epub file, I can rename test.peub to test.zip and then extract it and delete the META-INF/encryption.xml and again zip it and rename to sth.epub.
Now I can read that epub without DRM trouble. That means DRM is useless. Isn't it? How can I secure it more? |

All that means is that none of the content was actually encrypted.

Note that there are two different things that can have DRM applied. The book and the font and these are independent. Not that that changes anything but I thought it was worth mentioning.
