  <p>Furthermore, as I said in a comment, DAISY books come in different
  formats, independently of DRM, depending on whether they contain

  <p>I still do not know how to remove the DRM technically, and, if I knew,

  <p>To know more , I unzipped the file, which I hope you did too. This

  <p>They explain that the program (for modern books, hence under

  <p>Some countries do have laws that make a copyright exception to the
  benefit of disabled people within the country. I am not sure whether
  that is the case in the USA, but it would be the simplest
  explanation. However it does not explain giving access to American
  citizens in other countries, since international treaties give the USA
  jurisdiction on copyright only within the USA.</p>
  
  <p>Now if your country of residence has a similar law (free access for
  disabled people) then it is possible that the National Library Service
  would accept to give you a key to be used from your country, since
  that would not raise any copyright infringement issue (though they might want to have an official agreement between countries). Maybe you
  can try to discuss that with the people at info@archive.org, or the people
  at NLS. And you shold check the copyright law in your own country
  regarding exceptions for disabled people.</p>
  
  <p>This is just my best understanding, and all the suggestions I can give to solve your problem, and I am not a lawyer.</p>

  general and harder to answer. My answer suggests that it might be

Answers.Text: Sorry, but I can't stand answers like this. The questioner did not express any intent (evil or otherwise) and so to presume such on he behalf is a waste of time. Yes, it is true that people steal, but answering that you won't explain how to get into a home by picking a lock because it could be a question asked by a thief actually cuts out a lot of important cases where people genuinely do need help. Removing the DRM was the question, and if for whatever reason you can't answer, then simply don't. People don't care why, but that you answer or do not. Thanks, but didn't need all the warnings.

Title: Is there any way to remove DRM from DAISY ebooks?
UserDisplayName: Keshav Srinivasan
ThreadText: # Is there any way to remove DRM from DAISY ebooks?
  
  (Asked by: username_0 on 2017-06-13)
  
  DAISY is a digital ebook format designed for blind and disabled people. There are two kinds of DAISY books, "open" books which can be freely read by anyone, and "protected" books which have DRM and can only be read if you have a device equipped with a key.
  
  My question is, is there any way to remove/decrypt DRM from DAISY ebooks, if you don't have the key? There are methods for removing/decrypting DRM from PDF and EPUB files, so there may be similar methods here.
  
  EDiT: If it helps, [here](https://archive.org/download/asdrivenleaf00stei/asdrivenleaf00stei_daisy.zip) is the DAISY ebook I'm interested in downloading. I'd like to read this book on a computer if possible.
  
  EDIT 2: I found the same book as a PDF with DRM, and managed to decrypt the DRM on that. So now my question is moot. But let me leave it up so other people who encounter DAISY ebooks can get help.

  I have no idea on how to solve the general problem of DRM
  removal. Depending on where you live, it may actually be very much
  against the law.
  
  Furthermore, as I said in a comment, DAISY books come in different
  formats, independently of DRM, depending on whether they contain
  speech, text to be speech synthesized or both. I think the most common
  standard is DAISY 2.02, which (from what I understand) contains only
  speech, but I am no expert on DAISY which I never heard of before.
  
  I would expect that the type of DRM used is dependent on the standard,
  and may also depend on the publisher, or on the brand of the
  reader. Thus there may be no universal answer to your question.
  
  For a specific book, it may be useful to know the standard used, and
  probably the kind of reader, or the kind of DRM.
  
  Now, you tell in a comment, which you should (probably) integrate to
  your question to better focus it, that you are interested in the book
  at
  <https://archive.org/download/asdrivenleaf00stei/asdrivenleaf00stei_daisy.zip>
  
  I still do not know how to remove the DRM technically, and, if I knew,
  answering you could get me into significant trouble. The archive.org
  site is a wonderful site (I mean that), which by its very purpose is probably not too friendly to
  DRM, but there is nothing they can do when a book is still under
  copyright custody.
  
  To know more , I unzipped the file, which I hope you did too. This
  gives you a bunch of files, including a file README\_encrypted.txt
  which says it uses a key from the National Library Service, and point
