How to Start With Digital Signature

[Former Member]

Hi Wolfgang,

I open this thread in reference of the discuss in thread

I copy the text:

Hi Wolfgang,

Thanks for your quick response...

I don't have very clear what I want to use or which is the best way...I'm still in researching stage...:-) and customer hasn't allready specified what he wants...

We want to research and learn as many as we can to offer to customer the best alternative...

All I know is that customer would need:

- Single sign-on to the system, including SAP systems and Portal

- Digital signing documents.

They work with a local CA called Izenpe (www.izenpe.com) and they give you a SmartCard with your key...

I've found program SSFSDEMO and it works ok: it calls 'izenpe's libraries and sign the document ok. But I find the problem that the moment I call SSFS_CALL_CONTROL function I lose program control... I would prefer customize SAP using SIGNO,SIGNA, ELSIG00, ELSIG01...transactions to allow SAP user to sign or not, but sign with my certificate...

I don't have any external security product to configure...as far as I know customer is against paying for an any other product...

I've tried to sign using SSF* functions but as I've read it only runs to sign in WAS, is it true? it is not possible to sign in local? I allways get signature with server certificate, but not with my own certificate... :-((

What do you think? How do I start? Which is the best way?

Thank you very much for your help!

Regards.

Hello Urtzi,

to build a solution that meets the customer requirements (single sign-on to the system, including SAP systems and Portal, and digital signing documents - all using digital certificates), the customer will need a certified 3rd-party solution. If you want to investigate, you should start with the SAP Software Solution Partner Catalog at [http://sspcatalog.sap.com/catalog/index.jsp], and search for SSO and digital signature.

Urtzi,

If you need digital signatures to sign documents you can do this using SAPCRYPTOLIB, which is included in SAP product, and therefore no need to purchase any 3rd party product for this.

Thanks,

Tim,

this is not correct, if the customer wants to use Smarcards, as stated above.

Peter,

Thanks for highlighting the smart card reference. It is also true that the customer has not specified what they want, and Urtzi is just trying to find out what options are available during his research.

Regards,

Tim
