To install the SwissSigner Software follow the above instructions of the installation of the SuisseID Software. When this has been completed successfully, you can install the SwissSigner directly from the SwissSign Repository using the package manager of your Linux distribution:

Debian / Ubuntu

Graphical version: use the Software Center (Gnome) or Add/Remove programs (KDE)

command line: apt-get install swisssigner

SuSe

Graphical version: use YaST

command line: zypper in swisssigner

Redhat

Graphical version: PackageKit

To use SuisseID with SwissSigner please ensure the following:

 

  • The once-only initialisation of your SuisseID has been successfully carried out
  • The certificate carrier (USB reader, SwissStick or Card) is actively connected to the computer
  • The SuisseID software and the SwissSigner software have been installed

 

Two main goals are pursued with the digital signature/certification:

1. Integrity (inalterability)
The digital signature of documents guarantees that a document has not been changed since the time the signature was attached. If there are subsequent changes the signature will be displayed as «invalid» on the document.

2. Statement of will (legally binding)
A digital signature can also be used for a (legally binding) statement of will (content commitment). The «legal quality» of the digital signature varies according to which signature certificate is used (advanced, qualified) and in the case of qualified certificates is on a par with the manual signature according to the Swiss Signature Act ZertES.

The meaning and purpose of “certification” are described at the end of these instructions.

  • cleaned of active contents
  • provided with a digital signature

Instructions: SwissSigner multiple signatures

Put as many signature fields as you need (analogous to the single signature), put your signature in one of the fields.

Now the document can be signed by other persons (Fig. 9).

Instructions: SwissSigner signatures - special case certification

A PDF document can be visibly or non-visibly certified after completion. This means the author has no content commitment for the document but ensures that the content is not changed after he has worked on it.

In some cases the author of a document is not the person releasing the document who signs it. Examples:

 

  • Assistant draws up a contract for her supervisor
  • Web forms which have to be filled in – and otherwise remain unchanged – are made available on the homepage.

 

With the visible or non-visible certification only the form and signature fields can be filled in by third parties. The document is still displayed as “unchanged”.

For certification please proceed as follows:

Variant 1
Please click on Sign / Special / Multi-signature (Fig. 10):

anl ssigner 10

The next step is to place a field for the certification and another field for the countersignature.

Then click «certify » (Fig. 11)

For the other steps proceed according to the «Instructions: SwissSigner single signature».
