Digital Signatures
Digital signatures serve the same function for the processing of digital data as handwritten signatures do for paper documents.
You use digital signatures to sign digital documents. Digital signatures specifically identify the signer of a digital document and also protect the integrity of the document. Changes in signed documents are detected when verifying the digital signature.
Integration
You can use digital signatures in SAP systems either together with a security product or without. Security product, such as SAP Single Sign-On or an external security product, introduce features that are not directly available with the SAP system.
For more information, see the documentation for the area of the application that uses the digital signature.
