We would like to open an encrypted email (paystub) but we get the following message and epdfview won't accept the password (works in Windoz). Message:
Quote:
You now require Adobe Acrobat Reader 9.0 or greater to open your MAILSTUB.PDF attachment


Adobe is upgraded per last post (checked using page https://www.mozilla.org/en-US/plugincheck/ per an earlier suggestion)

The popup says:

Quote:
Encrpyted Document: This document is encrpyted and can't be accessed. Please enter the document's password.


Which just returns to the same message.

Looks like the problem is with epdfview not Flashplayer????

Most likely nothing to do with Flash, yes.

I'd imagine epdfview is just a 'basic' viewer and probably doesn't have much support for things like encryption. If you're wanting to view PDFs like that, you might have to install Adobe Reader for Linux (assuming it has the necessary features... Embarassed (You'd think they would (or should), though).)

Adobe flash player is not necessary for Adobe (PDF) reader to function.

Foxit PDF reader works on Puppy and can display encrypted PDFs, (128-bit encryption, dunno about 256-bit) ...

adobe.com wrote:
Compatibility
Sets the type of encryption for opening a password-protected document. If you choose Acrobat 3.0 And Later (PDF 1.3) option, a low-encryption-level security (40-bit RC4) is used. If you choose Acrobat 5.0 And Later (PDF 1.4) or Acrobat 6.0 And Later (PDF 1.5), a high encryption level (128‑bit RC4) is used. Choosing Acrobat 7.0 And Later (PDF 1.6) encrypts the document using the AES encryption algorithm with a 128-bit key size. Acrobat X And Later (PDF 1.7) encrypts the document using 256-bit AES.

Thanks Barkin, Makoto for clarifying what's what.

I see the Puppy Package Manager (under 'utility') can install Acrobat Reader 9.3.3, which should meet the above criteria, however, it will occupy too much space on my system (149kb, 28kb left!) The Foxit reader didn't appear to qualify and seemed too complicated (unless there's a .pet) for my noobiness so I'll probably park this project for awhile until I figure out which way to resolve this, but at least I know what has to be done.

Thanks again.

There appear to be online ways to decrypt a pdf with 256-bit encryption ...

Decrypt PDF online wrote:
Do not need Adobe Acrobat installed in a computer.
No installation, no registration, its free and easy to use.
Platform independce. No matter which system you use now, Windows XP, Windows 7, Linux, Mac OS X, IOS or Android.
Support up to Adobe Acrobat X, Standard RC4 40-bit, 128-bit, AES128(128-bit AES/AESV2) and AES256(256-bit AES/AESV3) encryption.
http://witwall.com/pdfdecrypt

but having this type of site decrypt your pdf could allow people to read its contents when it was decrypted or when the decrypted version was sent back to you, (via eavesdropping).

Semme good that you keep us informed on the dev of Flash.

My HP/Compaq Desktop has 64 bit
but the cool thing is that I did download
the 32 bit latest and that worked too.

so now I tested the 64 bit version and that worked too Smile

I presently have version 10.3.183.23 installed [and functioning well] on "Precise-5.6.1" [Linux 3.2.44 (32-bit)], browser = Nightly 16.0.1 [Mozilla Firefox].

I downloaded file "install_flash_player_11_linux.i386.tar.gz".
What should I do now?
