But here is a slide show of the various types of block encryption:

To answer your question, you have to know which of the above types is used by the DRM you are interested in making random access too.
For that information, you'll have to go to some other source of information than MobileRead.
Sorry, we don't disturb other people's I.P. here.

You had better check your prior source(s) of information, that is most likely **bits** not **bytes** (block sizes are usually referred to by their **bit length** in cryptology but I don't have a clue what is the common practice in DRM methods). |
Interesting, so I don't necessarily need to decrypt anything. To put it more succinctly I want to use Amazon's location values to extract passages from a .mobi, then decode them into legible text. The DRM is something slightly different although I'm also interested in it.
Though maybe the existing anti-DRM solutions will render the above impossible due to loss of interstitial meta data.
