The SAP System supports the following signature methods:

• System signature with authorization by user ID and password

Here, you do not need an external security product. Users identify themselves by entering their user IDs and passwords just like when logging on to the system. The SAP System then executes the digital signature, with the name and user ID being part of the signed document.

• User signature with verification

Here, you need an external security product. Users execute digital signatures themselves using their private keys. The signature created by the security product is automatically checked for authenticity.

• User signature without verification

If you use an external security product, you can use this signature method for test purposes but not in a live system. The user executes a signature as described above but automatic verification is switched off.
