Description mrx23 2022-07-06 08:29:28 UTC

I try to extract text from these epubs, all of them fail.

zipped: https://drive.google.com/file/d/1AtZbc9V7E0IVDDBWw-Eo7DQzQbV9QQA9/view?usp=sharing

(please ignore mobi file)

But files itself open correctly in SumatraPDF reader.
Lib could parse other epubs, just not these.
Seems to me this lib is to strict to the standard or something.

Oh yeah "Tor.." named also worked with the lib.

I renamed "Pandora.." and "The Bear" to .zip and could easily read xml text by hand.
So if I can do it by hand why can't the lib?

    Bug 705640: Don't always fail early on encrypted EPUB files.
    
    Check individual parts of the file for encryption by parsing out the
    encryption.xml file and storing the CipherReference URIs in a list.
    
    For now, we just throw an error whenever we try to open an encrypted
    entry in the EPUB. Eventually this can be extended to support decrypting
    the data, given access to the appropriate DRM keys.
