Accepted Answer

Can't afford Adobe Sign? Get KeepSolid Sign for less | ZDNet [ http://www.zdnet.com/article/cant-afford-adobe-sign-get-keepsolid-sign-for-less/ ]

In KeepSolid Sign [ https://www.keepsolid.com/sign/ ], a big attention developers pay for the user’s data safety.

That is why the main security features are:

1. Peer-to-peer. Using powerful protocols, so all data is stored and transmitted in encrypted form and is decrypted strictly after authorization on the user's device. Accordingly, only users are aware of the decrypted files, and no third party can invade and decrypt the data.
2. Data is transmitted over a secure https channel. We transfer data only through reliable and authorized sources, therefore bringing to nothing possibilities of man-in-the-middle attacks.
3. Multi-level data protection. We generate strong random keys and use the AES+RSA encryption combination. In such a way, we provide an additional layer of protection to our users regardless of their password strength.
4. Data distribution. The encrypted user data is not stored in one place, but distributed over several servers without the possibility of its partial full or even full interpretation. When some parties intercept your data, they will not be able to restore, decrypt, and aggregate it.
So, using the app, you may be calm for the data safety.

Question 5

For businesses adopting electronic invoicing, is there a preference between digitally signed PDF invoices and non-signed EDI inv

Accepted Answer

In my experience, I've seen a huge preference for EDI invoices over PDF for electronic invoicing.
 
About 15 years ago, I worked as a developer for a software consulting company, and I created a couple custom EDI interfaces.  I don't recall PDFs ever being mentioned.  A few years later, I switched to a different department that designs and maintains application software (which later became a separate company).  Because customer demand for EDI capability was high, one of the first things I did was rewrite the EDI interface so it was more flexible and easier to use.
 
I don't work with that stuff directly these days, but the department that handles that continues to grow.  We don't technically use the EDI format directly now though.  WalMart was the last holdout that I recall, where for a time we ended up doing the translation ourselves because they forced our customers to dial in (yeah, really) directly to them.
 
Now, when our customers have trading partners that require EDI, we'll send XML through a third party we have a business relationship with, and they'll handle the specifics.  Otherwise we use either XML or whatever special format the other side is requesting and typically send it directly to cut down the expense (especially if both sides are using our software).

I followed up on this with the person who handles this now in our company, and digitally signed PDFs aren't on our radar.  He mentioned a few additional authentication steps (I don't recall the specifics) that some companies require, but it wasn't signed PDF.

Question 6

How can I digitally sign a PDF document with a GNU Linux distribution?

Accepted Answer

To digitally sign a PDF the first thing you’ll need is a Certificate Manager or Certificate Management Tool like Kleopatra [ https://kde.org/applications/utilities/kleopatra/ ], EJBCA [ http://www.ejbca.org/ ], XCA [ http://sourceforge.net/projects/xca/ ], or OpenCA [ http://www.openca.org/ ]. Once you create your certificates you can then use LibreOffice [ https://www.libreoffice.org/ ] (Writer, Draw, Base, Calc, Impress) to sign a PDF.

The above menu is under File.

Question 7

How do I add amendments to a digitally signed contract in PDF format?

Accepted Answer

If you are simply *adding* the changes using digital signature aware PDF tools (such as Adobe Acrobat), then the signature will remain valid - for the portion of the file that it applies to. Of course, the PDF will show as modified since signing (since that is what you did), but that’s OK.
