Syntax Error: Invalid encryption key length

[Pierre Rudloff]

I am trying to open a password protected PDF from my university and Evince says that the password is wrong:
pierre@pierre-MacBook:~/Bureau$ evince Samuels_and_Witmer_and_Schaffner_2012_chap2.pdf
Syntax Error: Invalid encryption key length
Command Line Error: Incorrect password
Syntax Error: Invalid encryption key length
Command Line Error: Incorrect password

I know the password is correct because I can open it in Adobe Reader 11 on Windows.

For legal reasons I will just link to the pdf document without mentioning a password:
http://www6.rz.ruhr-uni-bochum.de:8205/ls-riesenhuber/lehrveranstaltungen/BGBII.html
Direct link.
http://www6.rz.ruhr-uni-bochum.de:8205/imperia/md/content/riesenhuber/veranstaltungen/01_sat_im_bgb.pdf

When trying to open the document with the newest evince/poppler combination I get the error message:

thomas@pluto ~ $ evince 01\ SAT\ im\ BGB.pdf
Syntax Error: Invalid encryption key length
Command Line Error: Incorrect password

And even after entering the password I get the same message again.

[Thomas (maxmusterm)]

Just to be precise I tested it with following combinations:
poppler 20.3 and evince 3.4
and
poppler git 20121020 rev and evince 3.4

If we don't have the password how do you expect us to fix the problem?

[Thomas (maxmusterm)]

I thought you can reproduce the problem and maybe fix it by just trying to open the file as well or is it impossible to see encryption details without actually encrypting it?I'm sorry I'm not sure I can give you the password.

[Albert Astals Cid (aacid)]

An encrypted file can't be opened without the password, that's the point. Without the password we can not check if we have fixed the bug or not, so i'm closing the bug since there is no way we can fix it.

Sorry about that but we don't do impossibles.

[Thomas (maxmusterm)]

The password is Medicus

[Albert Astals Cid (aacid)]

Wait, are you complaining of the error message only? Because the file is opened just fine here

[Thomas (maxmusterm)]

No Im unable Tod open the document.I used the standard archlinux package and compiled previously mentioned gibt Revision by Hand.It didn't work for me

[Albert Astals Cid (aacid)]

Confusing, it works just fine here, are you on 64 or 32 bits?

[Thomas (maxmusterm)]

I'm working on a 64bit system

[Jose-aliste-m (jose-aliste-m)]

I can open it in Fedora 17 64 bits both using distributed versions (evince 3.4 and poppler 0.18) and using compiled versions from git master.

I do get a different error on console though.
Syntax Error (95): Illegal character '}'

and an invalid password message, which is there because poppler always tries to open the file with the empty password first.

Not reproducible in Trusty.

[Albert Astals Cid (aacid)]

Thomas did you ever get a new poppler version? Is this fixed?
