ADE expiration date - where can I find it

[nhedgehog]

I'm looking for a way to view the ADE expiration date of an EPUB in the EPUB itself.
Afaik the only unencrypted files in a protected EPUB are:
mimetype
content.opf
and some files in \META-INF\
but not encryption.xml and rights.xml
Is there a metadata tag somewhere containing the expiration date?

Ups, I found it myself:
\META-INF\right.xml

- <permissions>
- <display>
<until>2015-08-01T22:00:00Z</until>
</display>
- <play>
<until>2015-08-01T22:00:00Z</until>
</play>
</permissions>

How interesting! Thanks for posting.

surely you just launch ADE - when I do that I see my current library loan epub books as thumbnails with a days-remaining slash banner superimposed on each
this is using the library view of all that's in the ADE local folder.
it changes to say "expired", if I've not returned & deleted before then

I wasn't probably clear enough.
I was searching those infos in the EPUB itself not in ADE.
To avoid further confusion I changed the first post accordingly.

technically you can't search the (original) epubs, they are encrypted.
if you search them post DRM removal, you can't know for sure what else may have been removed / altered. but best leave it there, this is not a forum for discussion of DRM mechanics

FYI My digital editions/manifest - has an xml per book with date & time therein. if may be in other locations also. I would guess that the manifest data feeds the library view screen.

e.g. for one of my current loans, the matching xml contains
<expirationTime xmlns="http://ns.adobe.com/digitaleditions">2017-03-07T19:27:14Z</expirationTime>

First, let me clarify:
I'm not attempting to discuss DRM removal here. I'm trying to collect infos I'm supposed to have (my expiration date), to show them on my devices.

Second:
No the epub is not encrypted, it is rather a container for some encrypted files and some not encrypted files.

i stand corrected on the encryption point.

so you are saying that if still had my old sony reader and I put a library loan onto it, I would not see the expiry date on the reader? ( I don't have one now so I cannot test & cannot remember - hence the question)
or likewise with the latest Kobo if I were to buy one and master the simple? steps to get a loaned book onto that ?

Frankly, I dont know. I was brainstorming to decide, whether it is worth the effort to include this into Selector. Still not sure about it.

The epub is not encrypted. Some of the files inside the .zip container are encrypted. In this case, opening a random selection of encrypted epubs with 7Zip and extracting the rights.xml showed none of instances were encrypted.

Hmmm... my library books borrowed on device using Overdrive show an "Expires in x days". I seem to remember that library books transferred via ADE showed the same.
