SDO seal and customer signature
To seal signed documents (SDOs) and to enable merchant signing for customer using Bank ID, a certificate will be created for the purpose. This certificate will be issued from a Nets internal utility CA and will be added during customer on-boarding.
To use the merchant signing feature with this certificate for some or all of your documents, add the below to your sign order:
Handling of SSN
The SSN will be incorporated as the subject serial number in the signing certificate and included as a part of the SDO if this has been a part of the authentication response. This may however differ from bank to bank. It also requires that the customer are allowed to get SSN in return.
How to find the SSN?
The SSN of a signer can be fetched from E-Signing using the
GetSignature call. This requires that the SignerID was set in the sign order. The SSN is returned in the SignerID / IDValue element of the response.
Use the GetSDODetails function to inspect the content of the SDO and return the SSN. For Bank ID this can be found in the UniqueId element in SDOSignature / SignerCertificateInfo.
See the SDOSignatures element.
