E-Signing validator

​The E-Signing validator can validate SDOs either manually by browsing for files or the customer can call the validator using HTTP POST to force validation of a specific SDO. The E-Signing validator is available at https://www.sign.nets.eu/validator/index.html.

General functionality​

The validator validates SDOs (Signed data object) and it offers this functionality:

  • Statement of the document validity
  • View the document
  • List of the signers
  • Document title
  • Information about the seal of the SDO

When the validator is used manually by browsing for a file, the document must be stored on disk with the file ending .sdo.
