Use
The digital signature is implemented in the SAP system by means of the Basis component Digital Signatures and Encryption and is based on Secure Store and Forward (SSF) mechanisms and public-key technology.
To use the digital signature, you must configure the SSF settings for the digital signature. These settings depend on the signature method you want to use.
The following signature methods are available:
- System signature
Authentification is done here using the SAP user master and the password of the signatory. This can be the user logged on to the system or another system user.
The SSF settings for the system signature are included in the standard system.
- User signature
Authentification is done here using a security product and not the SAP user master. You must integrate the security product in your SAP system with the aid of the component SSF.
Note that you should not store the users' Personal Security Environment (PSE) in the file system (hard disk) but rather, for example, on a smart card. The PSE software does not fulfill the regulatory requirements for digital signatures.
You decide which signature method you want to use in Customizing for the simple signature for each type of signature object or for the signature strategy.
Requirements
In addition to the Customizing activities, the digital signature (package DS in SAP_ABA) also provides a standardized programming interface with which you can integrate the digital signature in any application in an SAP system, such as ERP, APO, CRM. To be able to integrate the digital signature in an application, you must first make a series of settings and include the programming interface in your application. The settings are described in detail in the Implementation Guide Digital Signature Tool. You will find this guide in Note 700495. Only then can you execute the Customizing activities required for the digital signature.
Standard settings
Activities
SSF Settings for System Signature
If you want to use the system signature, you must check the default settings and change them if required. To do this, execute the following activities in Customizing under SAP NetWeaver -> Application Server -> System Administration -> Maintain the Public Key Information for the System:
SSF Settings for User Signature
If you want to use the user signature, you must execute the activity Maintaining Application-Dependent SSF Information in Customizing under SAP NetWeaver -> Application Server -> System Administration -> Maintain the Public Key Information for the System.
